This catalog is the product of many dedicated biologists
and resource managers working along the Oregon
coast over the past century, and in particular the past
25 years. The first Oregon coast-wide seabird colony
survey was conducted by Robert L. Pitman, Michael
R. Graybill, and Daniel H. Varoujean in 1979. In 1988,
the second coast-wide survey was conducted by Roy
W. Lowe, Jon B. Anderson, and Daniel R. Matthews.
The 1979 and 1988 surveys were made possible with
funding, staff and logistic support provided by the U.S.
Fish and Wildlife Service, Western Oregon National
Wildlife Refuge Complex. Refuge Manager Palmer C.
Sekora was instrumental in insuring that both surveys
were accomplished. Since 1988, surveys have been
conducted by U.S. Fish and Wildlife Service staff of the
Oregon Coast National Wildlife Refuge Complex. Roy
W. Lowe coordinated seabird surveys from 1986 – 1999;
David S. Pitkin assisted with surveys from 1993 – 1999
and coordinated surveys from 2000 – 2006.
The 1979 and 1988 coast-wide surveys did not include
the Columbia River Estuary, but data were collected
for these estuary colonies by Jim B. Atkinson, Alan
C. Clark, Douglas A. Bell, and David A. Manuwal
during comparable time periods. Since 1997, U.S.
Geological Survey has been monitoring the seabirds
of the Columbia River estuary. Daniel D. Roby,
Kenneth D. Collis, and students and staff of the
Oregon Cooperative Wildlife Research Unit have
monitored populations of Caspian Terns, Double-crested
Cormorants, and other seabirds in the estuary.
Janet Hodder provided data on Pelagic Cormorants
from the monitoring project she and students of the
University of Oregon's Institute of Marine Biology
(OIMB) have conducted at the "OIMB Cormorant
Colony" continuously since 1973. Many other biologists
contributed data for specific species or colonies; a
complete list of contributors is in Appendix A.
The catalog was assembled by Maura B. Naughton,
David S. Pitkin, Khemarith J. So, Craig S. Strong and
Roy W. Lowe. The databases were compiled and vetted
by Craig S. Strong, Khemarith J. So, David S. Pitkin
and Maura B. Naughton. Text sections were drafted by
Craig S. Strong and Maura B. Naughton. Khemarith
J. So and Mariana Lincoln developed and rectified
the GIS colony location databases and Khemarith J.
So produced the final colony maps and tables. Mary
Anderson produced the maps for Figure 2. Laurie
Litman, InfoWright, did the layout and design of the
final catalog. Ramiel Papish created the artwork for the
cover and throughout this catalog. Funding to compile
this catalog was provided by the U.S. Fish and Wildlife
Service, Division of Migratory Birds and Habitat
Programs, Pacific Region, Portland, Oregon.
The rocky islands and rugged habitats of the outer
Oregon coast and the low flat islands of the Columbia
River estuary provide habitat for approximately 1.3
million nesting seabirds representing 15 species.
Current and historical information on colony locations
and estimates of breeding seabirds were compiled into
databases, for all known seabird colonies in Oregon.
A total of 393 colonies were identified, and maps
and data tables for each colony are presented in this
catalog. The data tables include counts of nests and
Abstract
birds, where available, and estimates of the number
of breeding birds for each species at a colony. Specific
information regarding date, observers, type of survey,
quality of the estimate, and source of the data are
provided for each record. The geographic scope of this
catalog encompasses seabird colonies in marine and
estuarine environments. Marbled Murrelets, which
nest solitarily in habitats distinctly different from the
rest of the seabird community, are not included in this
catalog.
Abstract
Catalog of Oregon Seabird Colonies
The waters off the Oregon coast are part of the
California Current System, one of the most productive
marine habitats in the world. The rugged coast
encompasses large expanses of rocky shorelines,
islands, and offshore sea stacks, which provide nesting
habitat for seabirds. This Catalog of Oregon Seabird
Colonies presents a detailed record of seabird nesting
sites along the Oregon coast. For each of the 393
sites identified in this catalog, the location, species
composition, and abundance of breeding birds are
presented. Survey data from 1901 to 2004 are included.
Approximately 1.3 million seabirds, representing
15 species, nest in the state (Table 1, Figure 1).
This represents approximately half of the seabirds
breeding along the west coast of the conterminous
United States, including two species (scientific names
are in Table 1) of storm-petrels (Leach’s and Fork-tailed),
three species of cormorants (Double-crested,
Brandt’s, and Pelagic), three species of gulls (Western,
Glaucous-winged, and Ring-billed), one tern species
(Caspian), and six species of alcids (Common Murre,
Pigeon Guillemot, Marbled Murrelet, Cassin’s Auklet,
Rhinoceros Auklet, and Tufted Puffin). One shorebird
species (Black Oystercatcher) is also included because
of its strong affiliation with marine habitats and the
high degree of overlap between seabird and Black
Oystercatcher nesting sites. Marbled Murrelets nest
solitarily in forest habitats distinctly different from
other Oregon seabirds, and are not included in this
catalog. Readers are referred to Ralph et al. (1995)
and McShane et al. (2004) for further information on
Marbled Murrelet abundance and nesting distribution
in Oregon.
This catalog it restricted to seabird species that
breed along the coast and in the lower estuaries
within Oregon state boundaries. It does not include
the millions of marine birds that breed elsewhere
and migrate to Oregon’s rich coastal waters, such as
albatrosses that nest in the central Pacific, shearwaters
from the southern hemisphere, and loons, grebes,
sea ducks, and gulls that breed in the arctic or
inland colonies. At-sea, these migrant species often
outnumber Oregon’s breeding seabirds and, although
they are not covered in this catalog, they represent a
significant component of Oregon’s marine community.
Along the Pacific coast, seabird colony catalogs have
been published for Alaska (Sowls et al. 1978), California
(Sowls et al. 1980), and Washington (Speich and Wahl
1989). Similar catalogs of colonies in British Columbia,
Canada have also been published (Drent and Guiguet
1961, Campbell et al. 1990). The first comprehensive
survey of Oregon seabird colonies was conducted in
1979 (Varoujean and Pitman 1980) and a draft catalog
was prepared (Pitman et al. 1985), but never published.
Another complete survey of Oregon colonies was
conducted in 1988. In addition to these comprehensive
surveys, numerous other surveys of specific species
at specific colonies have been completed, including,
since 1988, annual aerial photographic surveys of
Brandt’s and Double-crested cormorants and Common
Murres (all colonies have been photographed annually
and a subsample of the colonies have been counted;
see Methods), and a coast-wide survey of cormorant
colonies in 2003. This catalog provides a compilation of
current and historic seabird colony information.
This catalog was designed primarily to provide
biologists, resource managers, regulatory agencies,
and researchers with the best available data on the
size and location of Oregon seabird colonies, in a
standardized format. The information compiled here
serves as a baseline of recent and historic distribution
and abundance of breeding seabirds in the state.
In the event of an oil spill or other catastrophic
occurrence, this catalog can provide quick reference to
concentrations of breeding seabirds. The catalog will
also be useful to community planners and members
of the general public interested in increasing their
understanding of Oregon’s diverse seabird community.
Finally, future surveys and monitoring can be planned
with a better understanding of the dynamics of seabird
breeding biology and colony distribution.
Speich and Wahl (1989) noted in the introduction to the
Catalog of Washington Seabird Colonies that, from its
inception, the catalog was destined to be incomplete.
The same is true for all colony catalogs. New surveys
are continually underway and reports of historic
surveys are often incomplete.

Summary of Seabird Distribution and
Abundance in Oregon
The Columbia River demarcates Oregon’s border
with Washington and is the location of Oregon’s
northernmost seabird colonies. The low, sandy islands
in the Columbia River estuary support the largest
colonies of Caspian Terns (19,000 breeding birds) and
Double-crested Cormorants (26,000 breeding birds) in
North America, the largest Western/Glaucous-winged
gull colonies in the state (16,000 breeding birds), and
the only active breeding colonies of Ring-billed Gulls
(400 birds) along the Pacific coast (Figure 2). Loss and
changes to estuary islands and artificial habitats in
Washington, and movement of birds from outer coast
and inland colonies, have likely contributed to the rapid
increases in the Columbia River colonies over the past
decade.
Along the outer coast, the vast majority of Oregon’s
seabirds nest within the Oregon Coast National
Wildlife Refuge (NWR) Complex. The northern
Oregon coastline is composed of grand headlands
interspersed with sweeping beaches and estuaries.
Headland cliffs and offshore rocks support large
numbers of nesting seabirds. The largest colony in the
state occurs at Three Arch Rocks NWR, where over
225,000 seabirds of 10 species nest. Most of the state’s
Tufted Puffins nest on Finley Rock, a large vegetated
island within Three Arch Rocks NWR and on the two
northernmost Haystack Rocks within Oregon Islands
NWR.
The central Oregon coast is dominated by extensive
sandy beaches, many of which are within Oregon
Dunes National Recreation Area managed by the
Bureau of Land Management. Relatively few seabirds
nest along this stretch of coastline, and colonies are
largely limited to the rocky cliffs and nearshore islands
from Depoe Bay to Newport and at Heceta Head/Sea
Lion Caves (Figure 3). Some birds (primarily Western/
Glaucous-winged gulls, Double-crested Cormorants
and Pigeon Guillemots) nest opportunistically on
artificial structures within estuaries and Double-crested
Cormorants nest in trees in several locations
along the central coast.
Southern Oregon is particularly rich in offshore sea
stacks and rocky coastline, and more than half of the
colonies in the state (203 of 393) are located here. Most
of the state’s Leach’s Storm-Petrels nest on a few
southern Oregon islands with well established soil and
vegetation.
Numerically, Common Murres dominate the Oregon
seabird community (approximately 685,000 breeding
birds). Common Murres constitute more than half of
all seabirds nesting in Oregon and greater than 65% of
the breeding U. a. californica subspecies, rangewide
(Carter et al. 2001). Common Murres nest in extremely
dense colonies, typically on the top of islands and sea
stacks, and have proven to be important indicators of
marine productivity.
Leach’s Storm-Petrels are the second most abundant
breeding seabird in Oregon, with an estimated 480,000
birds nesting at 21 colonies. The overwhelming
majority of Leach’s Storm-Petrels nest on seven small
islands off the southern Oregon coast (Saddle Rock,
Crook Point Rock, Hunters Island, Goat Island, two
rocks off Whaleshead Cove, and an unnamed island
in Boardman State Park). Due to their small size,
nocturnal activity and burrow nesting habit, estimates
of both Leach’s and Fork-tailed storm-petrel colony
sizes are difficult to obtain, and estimates are often of
low reliability compared to other species.
Gulls are the most readily identified seabird by casual
visitors to the coast. Western Gulls are the dominant
nesting gull species throughout the outer coasts of
California and Oregon, and Glaucous-winged Gulls
are more common in Washington, but the two species
readily hybridize and intermix through central and
northern Oregon and along the Washington coast
(Scott 1971, Bell 1996). Clear distinction of species is
difficult in this area of overlap; therefore, large gulls
are listed as Western/Glaucous-winged gulls in this
catalog. The largest concentration of nesting gulls is in
the Columbia River estuary, where half of the state’s
32,300 Western/Glaucous-winged gulls breed. Ring-billed
Gulls also nest in the estuary. Coastal colonies,
such as the one at East Sand Island, are rare for Ring-billed
Gulls, which typically nests at inland locations.
They first colonized the Columbia River estuary in the
late 1990s. A list of active colonies for each species is
presented in Appendix B, including the most recent
accurate or representative estimate of the number of
breeding birds at each site.

Methods
The information compiled in this catalog comes from
five primary sources:
■ U.S. Fish and Wildlife Service (USFWS) surveys:
• 1989 – 2004, annual aerial photographic surveys
of Common Murre and Brandt’s Cormorant
colonies (all colonies photographed, with a subset
of 31 Common Murre and 25 Brandt’s Cormorant
colonies counted each year) (Carter et al. 2001,
USFWS unpublished data);
• 2003 coastwide survey of all Pelagic, Double-crested,
and Brandt’s cormorant colonies
(USFWS unpublished data);
• 1988 comprehensive coastwide survey of
all seabird species at all colonies (USFWS
unpublished data);
• 1979 comprehensive coastwide survey of all
seabird species at all colonies (Varoujean and
Pitman 1980, Pitman et al. 1985).
• 1966 – 1975, annual aerial surveys (visual
estimates) of major Common Murre and
Double-crested and Brandt’s cormorant colonies
(USFWS unpublished data).
■ U.S. Geological Survey (USGS) surveys of Caspian
Tern, Western/Glaucous-winged and Ring-billed
gull, and Double-crested Cormorant colonies in the
Columbia River estuary, 1998 – 2004 (Collis et al.
2002, USGS unpublished data).
■ Oregon Institute of Marine Biology (OIMB) annual
surveys of Pelagic Cormorants at “OIMB Cormorant
colony,” near Cape Arago, 1973 – 2004 (Jan Hodder,
OIMB unpublished data).
■ Historical records from published and unpublished
sources.
Survey methods vary by species, location, size of
colony, logistics, and personnel/organization conducting
the surveys. Surveys were conducted from boats,
aircraft, ground surveys from remote vantage points,
and ground surveys within the colony. In general, four
techniques have been employed: (1) counts of nests,
either directly or from aerial photographs; (2) counts
of adult birds on or around the colony, either directly
or from aerial photographs; (3) sampling to estimate
burrow density and occupancy rates, combined with
estimates of colony area; and, (4) crude estimates of
nests, birds, or burrows.
In this section, methods used during the 1979 and
1988 statewide surveys, and the methods employed
by USFWS from 1966 through 2004, are described.
Brief summaries of USGS methods employed in the
Columbia River estuary and OIMB methods at the
Cape Arago cormorant colony are also included. No
attempt is made here to provide detailed descriptions
of all methods employed to obtain the data presented
in this catalog. Readers are referred to the references
listed after each data entry in the tables for specific
methods.
Boat and Ground Surveys
During both coastwide surveys, boat and mainland
surveys were conducted of all rocks and mainland
colony sites from West Point (north of Tillamook
Head) to Florence, and Coos Bay to the California
border (Figure 4). The remaining sections of coast
are dominated by sandy beaches, with no offshore
rocks, and they were not surveyed by boat. During
boat surveys, larger rocks were circumnavigated and,
if conditions were favorable, surveyors landed and
occasionally camped overnight. Brief descriptions
of the rocks and islands were recorded, including
approximate height, soil, vegetation, and any other
salient features that might aid future workers in
accurately relocating the sites (Appendix C).
The majority of the 1979 survey was conducted from
a 4 meter (14 foot) inflatable boat (Zodiac) powered
by a 25-hp outboard motor. In 1988, surveys were
conducted from 4 – 6 meter (14 – 20 foot) inflatable
boats with 30-hp outboard motors. Two or three
biologists participated in all boat surveys, using 7 – 10
power binoculars. Data were recorded in notebooks
and later transcribed to data sheets and entered into
an electronic database.
Shore-based Surveys
Use of high power spotting telescopes from high,
stable vantage points afforded the best views of some
colonies. Counts of Tufted Puffins at Haystack Rock
(Clatsop County), Bandon rocks, and miscellaneous
observations of puffins at other sites were made from
shore. Annual colony counts of Pelagic Cormorants,
Western Gulls, and Pigeon Guillemots at Yaquina
Head were derived from a combination of shore and
boat-based surveys. The long-term monitoring of the
Pelagic Cormorant colony at Cape Arago by OIMB was
conducted from shore.

12 Catalog of Oregon Seabird Colonies
Aerial Surveys
The most significant changes in survey methods
over the past 40 years have been improvements and
refinements of aerial survey protocols. From 1966
to 1975, USFWS conducted annual aerial surveys of
Common Murre and cormorant (species not identified)
colonies along the entire Oregon coast using fixed-winged
aircraft. These surveys generally targeted only
the larger concentrations of Common Murres, and
Brandt’s and Double-crested cormorants, and were
not designed to be comprehensive. Visual estimates
of colony size were made by a single observer during
a one day survey of the entire coast. In 1979, several
aerial surveys were conducted (Pitman et al. 1985).
On 19 April, 1979, all major colony sites along the
coast were photographed from a single-engine Cessna
aircraft. Although too early in the season for maximum
seabird attendance at colonies, the flight served as
an orientation flight to identify colonies. Later in
the season four aerial surveys were made from U.S.
Coast Guard Sikorsky helicopters. All major colonies,
including nearly every Common Murre and Brandt's
Cormorant colony, were photographed on at least two
occasions. Photographs were taken using 35 mm SLR
cameras equipped with 200 mm and 300 mm focal
length lenses and ASA 64 and 400 color slide film.
Beginning in 1988, the timing of aerial photographic
surveys was standardized to facilitate comparison
between years (Carter et al. 2001). Small, quiet
helicopters (Hughes 500, models D & E) with the doors
removed were used to minimize disturbance to the
colonies and improve the quality of the photographs.
Colony photographs were taken by two photographers
using 35 mm cameras. Common Murres, Brandt’s
and Double-crested cormorants, and Western/
Glaucous-winged gulls have been counted from these
photographs.
Aerial photographic surveys of islands in the Columbia
River estuary have been conducted by USGS since
1997. See Collis et. al. (2002) for a detailed description
of survey methods at these colonies.
Methods of Estimation
Colony estimates based on direct nest counts provide
the most accurate information, and this method was
used whenever possible. Virtually all Double-crested,
Brandt’s, and Pelagic cormorant estimates were
obtained using this method. Western/Glaucous-winged
gull estimates (except in the Columbia River estuary)
were also derived from nest counts. These species build
conspicuous nests which are relatively easy to detect.
Direct nest counts were also employed whenever
possible to estimate Tufted Puffin breeding numbers,
but their burrow-nesting habit made the results less
reliable.
Estimates based on the total number of adults present
on the colony were used for those species whose
nests are difficult to find and for species that nest in
dense colonies, where it is difficult, or impossible, to
distinguish breeding from nonbreeding individuals.
Pigeon Guillemots and Black Oystercatchers are
often quite conspicuous around nesting colonies,
but their actual nest sites are difficult to locate.
Estimates presented in this catalog for these two
species represent the number of adult birds seen in
the vicinity of appropriate nesting habitat, unless
otherwise noted. Common Murres and Caspian Terns
nest in large, dense colonies. Estimates of colony size
for these species were based on counts of adult birds
on the colony (from aerial photographs), adjusted by
a correction factor, to account for breeding birds away
from the colony and non-breeding birds in attendance.
Burrow-nesting species were the most difficult to
estimate. When possible, colonies were directly
sampled to estimate burrow density and occupancy
rates. The total area of the colony was then estimated
in the field or from aerial photographs. Density of
active burrows was combined with estimates of colony
area to generate colony estimates.
Species-Specific Methods
Cormorants
Pelagic Cormorants typically nest in small colonies on
steep cliffs or artificial structures. Boat- or ground-based
surveys were the best means to survey these
colonies. The longest time series data set for Pelagic
Cormorants in Oregon is from the OIMB Cormorant
Colony at Cape Arago. Surveys of this colony have
been conducted from shore since 1973 by staff and
students from Oregon Institute of Marine Biology (J.
Hodder, pers. comm.).
Double-crested and Brandt’s cormorants typically
nest on broader cliff ledges or the tops of islands or
headlands where they can be effectively surveyed
using high quality aerial photography. Nests are
easily identified and counted from projected slides.
Double-crested Cormorants also nest in trees, channel
markers, bridges, and other structures where new or
small colonies can go undetected, especially during
aerial surveys. In some colonies (e.g., Three Arch
Rocks, Cape Lookout, and Island Rock), Double-crested
and Brandt’s cormorants intermix. Distinction
between species can be difficult at these colonies if
aerial photographs are not high quality. Combining
aerial surveys with ground or boat surveys is often
necessary to determine the species composition at
these sites.
From 1966 to 1975, USFWS conducted annual aerial
surveys of the major Brandt’s and Double-crested
cormorant colonies along the entire Oregon coast,
using fixed-winged aircraft. These surveys, conducted
in June or July, were completed in one day and the
visual estimates did not identify cormorants to species.
Beginning in 1979, aerial photographs were utilized in
conjunction with ground and boat-based surveys. Since
1988, timing of the surveys has been standardized to
coincide with the two-day aerial survey of Common
Murres flown annually in early June. (See Common
Murre methods for specifics regarding aircraft and
photography.)
Statewide surveys of all Double-crested, Brandt’s, and
Pelagic cormorant colonies were conducted in 1979,
1988, and 2003. Between 1988 and 2003 (except 1995),
almost all Brandt’s and Double-crested cormorant
colonies were photographed annually, and a sample
of 25 colonies was counted each year. Photographs of
the other colonies were labeled and archived, but not
counted.
Brandt’s and Double-crested cormorants exhibit
relatively low site fidelity. For surveys of the entire
coast, this was not an issue since all colonies were
counted and most movement between colonies was
captured. However, monitoring trends of single
colonies, or small groups of colonies, can lead to
erroneous conclusions if birds move between sampled
and un-sampled colonies.
Common Murre
In Oregon, Common Murres nest on the tops of islands
or on mainland cliffs in large, dense colonies. Common
Murres do not build nests, and colony estimates are
based on counts of adult birds on the colony. From
1966 to 1979, Common Murre colonies were surveyed
by visual estimates of breeding birds from a fixed
wing airplane. Given the high densities and large size
of Oregon Common Murre colonies, these estimates
were generally very poor quality. Counts from aerial
photographs were first used in 1979 (Pitman et al.
1985), however; biologists had limited control over the
timing of the surveys and many of the photographs
were taken too late in the season to accurately census
breeding murres.
Since 1988, single annual aerial photographic surveys
of all major Common Murre colonies in Oregon have
been conducted (except 1995) using standardized
techniques. Surveys were flown in early June to
coincide with late incubation and hatching (after
Takekawa et al. 1990), using a Hughes 500 helicopter
(models C, D and E) or a Bell helicopter at altitudes
of 260 – 330 m with side doors removed. Colony
photographs were taken by two photographers using
35-mm cameras with 100 – 400 or 300 mm lenses for
close-up photographs (front-seat photographer) using
ASA 400 color slide film and shutter speeds less than
1/1000 per second, and 55- or 70 – 210-mm lenses for
colony overviews (back-seat photographer) (Carter
et al. 2001). Overlapping colony slides were projected
onto large sheets of paper, simultaneously using
3 – 4 projectors, and individual birds were counted.
These data were transferred to data sheets and
computerized. A general k-correction factor of 1.67
(based on California data) was applied to all count data
to estimate the number of breeding adults at colonies
in Oregon (Carter et al. 2001). A specific k-correction
value for Oregon colonies has not been researched.
All Common Murre colonies were photographed
annually between 1988 and 2004, and a subsample of
31 colonies was counted annually. Photographs of the
other colonies were labeled and archived. In the data
tables of this catalog, the actual counts of Common
Murre adults and the estimated number of breeding
birds (bird count x 1.67) are both reported.
Pigeon Guillemot
Pigeon Guillemots nest in rock crevices and burrows,
and nests are extremely difficult to locate and count.
Pigeon Guillemots are social birds and they gather
on the rocks and in the water adjacent to nesting
areas early in the season. Repeated counts of Pigeon
Guillemots on the water during early morning or
evening in late April and May show little daily variation
and presumably represent an index of the nesting
population (Ainley et al. 1990). Counts generally
decrease by late morning and are lower through the
middle of the day (Carter et al. 1992). Counts also
tend to be lower later in the season, since one pair
member is incubating or both members are foraging
more actively during the chick-rearing period. Counts
presented in this catalog were not standardized for
time of season or time of day, so colony sizes were likely
underestimated. Counts of Pigeon Guillemots during
El Nino years might be higher than expected if few
birds are nesting and more are visible on the water
near the colony (Jaques and Strong 2001).
Tufted Puffin
Tufted Puffins can be counted outside nesting burrows
early in the season, particularly during the morning
hours. Unlike Pigeon Guillemots, Tufted Puffins
engage in frequent flights, entries and departures from
burrows, and exhibit variable activity levels through
the day, confounding any attempt to get an index of
the breeding population based on a count of adults.
Estimates were typically derived from a ground count
of appropriately sized burrows (often obtained after
Methods 13
14 Catalog of Oregon Seabird Colonies
the nesting season on islands with nesting Common
Murres). At some colonies, the presence of Tufted
Puffins was noted and a rough estimate was generated
based on the number of sightings and the amount of
suitable nesting habitat.
Small Nocturnal Burrow-Nesting Species
Fork-tailed and Leach’s storm-petrels, and Rhinoceros
and Cassin’s auklets are nocturnal burrow nesters,
and estimates of colony size are particularly difficult
to obtain. Estimates of colony size are of poor quality;
far less precise than for surface nesters, and may
only be accurate within an order of magnitude except
where intensive surveys were conducted. Only a few
Oregon islands have soil of sufficient depth to support
burrow nesting. Observations from a remote vantage
point are not possible, even for Rhinoceros Auklets
that are active at dusk. The rugged nature of Oregon’s
islands and the presence of breeding murres at many
sites precludes ground surveys of most of the islands.
Estimates of Cassin's and Rhinoceros auklet colonies
were based on observations of birds close to the colony
(often "staging" at dusk) or the availability of suitable
nesting habitat. Only a few estimates were based on
visits to the colonies during the nesting season.
In 1979 and 1988, estimates of Leach's Storm-Petrel
numbers at Goat Island, Hunters Island, and Saddle
Rock were derived from density estimates of burrows
in specific nesting habitat types, coupled with an
estimate of the total area of each habitat type. In 1979,
rough estimates of breeding Leach’s Storm-Petrels
were also generated for islands where breeding was
known to occur, but which were surveyed only briefly
or not at all. At these islands, the area of potential
nesting habitat was visually estimated and density
estimates from Goat Island (2.4 breeding birds/m2)
were applied to calculate a rough estimate of the
potential Leach's Storm-Petrel breeding population.
In 1988, presence or absence of Leach’s Storm-Petrels
was noted for colonies that could not be surveyed
on the ground, but numerical estimates of colony
size were not made for these colonies. Thousands of
Leach’s Storm-Petrels have been banded at Saddle
Rock in southern Oregon between 1979 and 2004, and
mark-recapture techniques are being investigated as a
monitoring tool at this colony.
Western and Glaucous-winged Gulls and Hybrids
Western/Glaucous-winged gulls are opportunistic in
selection of nesting substrate and habitats. They nest
on a variety of structures (roof tops, pilings, bridges,
islets) and small colonies can be missed. A combination
of boat, ground, and aerial surveys were used to count
Western/Glaucous-winged gull nests at various sites
during the two statewide surveys. Annual aerial
photographic surveys were conducted by USGS at the
East Sand Island colony in the Columbia River in 1997
and 1998 (Collis et al. 2002). Since 1999, aerial
photographs have been taken and archived (D. Roby,
pers. comm.). Counts of nests were the basis for colony
estimates at all sites except colonies in the Columbia
River estuary, where adults were counted from aerial
photographs. A specific k-correction factor has not
been researched for the estuary colonies (the largest
concentration of nesting gulls in Oregon), so the
k-value of 1.4, calculated for Western Gulls in California
(Carter et al. 1992), was substituted. Both the actual
count of birds and the estimated number of breeding
birds at these colonies are presented in the data tables.
Oregon is in the zone of hybridization between Western
and Glaucous-winged gulls (Scott 1971, Hoffman 1978,
Bell 1996). While hybridization between these species
occurs as far south as central California, most nesting
gulls on the southern and central Oregon coast are
Western Gulls (Bell 1996, D. Pitkin, pers. comm.).
In 1989, Bell (1996) found that approximately half
of the gulls nesting in the Columbia River estuary
were Glaucous-winged or hybrids. These Columbia
River colonies have increased in size by an order of
magnitude since 1989, and the proportion of hybrids
appears to have increased also. Determination of
hybrid status is impossible from the air. All estimates
in this catalog are reported as Western/Glaucous-winged
gull, but the proportion of Western Gulls,
Glaucous-winged Gulls, and hybrids varies at each site.
Caspian Tern
Aerial photographic surveys of Caspian Tern colonies
in the Columbia River estuary have been conducted
annually by USGS since 1997 (Collis et al. 2002).
Intensive ground surveys of Caspian Tern plots were
conducted each year in conjunction with the aerial
surveys to generate k-correction factors which were
then applied to bird counts to estimate the number
of breeding birds. See Collis et al. (2002) for a more
detailed description of survey methods at these
colonies.
Maps and Data Tables
How to Use This Catalog
The following section consists of maps denoting the
location of each seabird colony and accompanying
tables with recent and historical estimates of the
number of breeding birds, for each species, at each
colony. Figure 5 presents an example of a data table
with an explanation of the columns and the codes.
Colony Numbers and Names
Oregon seabird colonies were assigned unique
identifying numbers during the 1988 statewide survey,
according to the numbering convention used for the
California and Washington seabird colony catalogs
(Sowls et al. 1980, Speich and Wahl 1989). The Oregon
coast was divided into five areas delineated by degree
of latitude and corresponding to USGS 1:250,000
topographic maps (Figure 6). These USGS maps
were sequentially numbered for the conterminous
United States as the basis for a standardized colony
numbering system for waterbirds (Spendelow and
Patton 1988). Within each map area, colonies were
numbered north to south with the first three digits
designating the map, and the next three digits
representing the site number, beginning with 001.
When new colonies were discovered following the initial
number designation in 1988, they were given a decimal
extension of the number of the nearest original colony.
For example, 219-001.1 was a colony discovered after
1988 adjacent to colony 219-001.
Colony names were derived from maps or charts
whenever possible. If a location did not have an
official name and a descriptive name was assigned
by a surveyor, then this name is reported in quotes
to indicate that it cannot be found on maps. All other
colonies were labeled “Unnamed Colony” and the
colony number is the identifier.
Most Recent or Representative Estimate
The data tables contain all of the recent and historic
estimates of colony size. The most recent, accurate
or representative (MRA) estimate for each species is
presented at the top of the table in a box. MRA data
were used to generate total statewide estimates for
each species.
For most species and most colonies, MRA data were
the most recent estimates. However, if the most recent
estimate was poor quality (e.g., non-quantitative
estimate such as “present”) and an earlier, quantitative
estimate of higher quality was available, then the
earlier estimate was presented in the MRA box at
the top of the table and the more recent estimates
were presented below. If the most recent data were
collected during an El Niño year, or were otherwise
not representative of the numbers of birds that
typically nest at a particular colony, then these data
were presented in the table but the most recent
“representative data” were presented in the MRA
box at the top of the table. (El Niño events affected
Oregon in 1993 and 1997 and estimates from these
years are not presented in the MRA box.) Another
situation where the most recent data were not the
most representative data involved Common Murre
and Double-crested and Brandt’s cormorant colonies
harassed by Bald Eagles (Haliaeetus leucocephalus).
Bald Eagles have increased along the Oregon coast,
and harassment of colonies, especially in the northern
section of the state, has resulted in nesting failure and
early abandonment of some colonies prior to early
June, when aerial surveys normally occur. In a few
instances, estimates from a previous year that were
more representative of the number of birds at a given
colony were presented in the MRA box at the top of the
table.

Data Quality (Q).—This code describes how accurately
the data reflects the actual number of breeding birds of
each species in the colony. Data quality can be affected
by many factors such as survey conditions, biology of
the species, and methods employed.
Code Description
1 A direct count of all nests in a colony
(onsite or aerial photograph) or a precise
estimate of the number of breeding birds.
Examples of data of this quality include
aerial photo surveys of cormorant nests
or counts of gull nests from boat or shore.
These data can be used to detect annual
change in colony size.
2 A direct count of adult birds at a colony
with quantification of the number of
nests (or breeding pairs) represented
by adults at the colony (a k-correction
factor), or repeated counts of birds using
standardized techniques. Examples
of quality data 2 include aerial photo
surveys of Caspian Terns and Double-crested
Cormorants at the Columbia
River colonies; aerial photo surveys
of Common Murre colonies; and,
repeated, standardized surveys of Pigeon
Guillemots. Changes in number of birds
and long-term trends can be detected
using data of this quality.
3 A count or estimate of adults birds at or
near a colony, where k-correction factors
are not available. Examples of data
quality 3 include single surveys of Pigeon
Guillemots or Tufted Puffins, or nest
counts where only a portion of the nests
are visible.
4 A rough estimate of colony size that
is only reliable within an order of
magnitude, at best. Examples of data
quality 4 include presence/absence
observations, or rough visual estimates
of colony size (e.g., ‘hundreds’, or
‘several thousand’), or most estimates of
nocturnal burrow-nesting species. These
data are of limited value and should only
be used to document extremely large

32 Catalog of Oregon Seabird Colonies
The map on the facing page is an index to the locations and relative sizes of seabird colonies within map 219,
Vancouver, located along the northern Oregon coast. To reduce the complexity of this index, adjacent colonies
are grouped together and the individual colonies in each group are indicated by the inclusive site numbers,
separated by an arrow. On the pages following this map, all colonies are listed sequentially and a detailed map of
each is provided.
Numbers of breeding seabirds will vary from year to year. Below are the most recent estimates of breeding
seabirds within this region:
Fork-tailed Storm-Petrel +

The first Oregon coast-wide seabird colony survey was conducted by Robert L. Pitman, Michael R. Graybill, and Daniel H. Varoujean in 1979. In 1988, the second coast-wide survey was conducted by Roy W. Lowe, Jon B. Anderson, and Daniel R. Matthews. The 1979 and 1988 surveys were made possible with funding, staff and logistic support provided by the U.S. Fish and Wildlife Service, Western Oregon National Wildlife Refuge Complex. Refuge Manager Palmer C. Sekora was instrumental in insuring that both surveys were accomplished. Since 1988, surveys have been conducted by U.S. Fish and Wildlife Service staff of the Oregon Coast National Wildlife Refuge Complex. Roy W. Lowe coordinated seabird surveys from 1986 – 1999; David S. Pitkin assisted with surveys from 1993 – 1999 and coordinated surveys from 2000 – 2006. The 1979 and 1988 coast-wide surveys did not include the Columbia River Estuary, but data were collected for these estuary colonies by Jim B. Atkinson, Alan C. Clark, Douglas A. Bell, and David A. Manuwal during comparable time periods. Since 1997, U.S. Geological Survey has been monitoring the seabirds of the Columbia River estuary. Daniel D. Roby, Kenneth D. Collis, and students and staff of the Oregon Cooperative Wildlife Research Unit have monitored populations of Caspian Terns, Double-crested Cormorants, and other seabirds in the estuary. Janet Hodder provided data on Pelagic Cormorants from the monitoring project she and students of the University of Oregon's Institute of Marine Biology (OIMB) have conducted at the "OIMB Cormorant Colony" continuously since 1973. Many other biologists contributed data for specific species or colonies; a complete list of contributors is in Appendix A. The catalog was assembled by Maura B. Naughton, David S. Pitkin, Khemarith J. So, Craig S. Strong and Roy W. Lowe. The databases were compiled and vetted by Craig S. Strong, Khemarith J. So, David S. Pitkin and Maura B. Naughton. Text sections were drafted by Craig S. Strong and Maura B. Naughton. Khemarith J. So and Mariana Lincoln developed and rectified the GIS colony location databases and Khemarith J. So produced the final colony maps and tables. Mary Anderson produced the maps for Figure 2. Laurie Litman, InfoWright, did the layout and design of the final catalog. Ramiel Papish created the artwork for the cover and throughout this catalog. Funding to compile this catalog was provided by the U.S. Fish and Wildlife Service, Division of Migratory Birds and Habitat Programs, Pacific Region, Portland, Oregon. The rocky islands and rugged habitats of the outer Oregon coast and the low flat islands of the Columbia River estuary provide habitat for approximately 1.3 million nesting seabirds representing 15 species. Current and historical information on colony locations and estimates of breeding seabirds were compiled into databases, for all known seabird colonies in Oregon. A total of 393 colonies were identified, and maps and data tables for each colony are presented in this catalog. The data tables include counts of nests and Abstract birds, where available, and estimates of the number of breeding birds for each species at a colony. Specific information regarding date, observers, type of survey, quality of the estimate, and source of the data are provided for each record. The geographic scope of this catalog encompasses seabird colonies in marine and estuarine environments. Marbled Murrelets, which nest solitarily in habitats distinctly different from the rest of the seabird community, are not included in this catalog. Abstract Catalog of Oregon Seabird Colonies The waters off the Oregon coast are part of the California Current System, one of the most productive marine habitats in the world. The rugged coast encompasses large expanses of rocky shorelines, islands, and offshore sea stacks, which provide nesting habitat for seabirds. This Catalog of Oregon Seabird Colonies presents a detailed record of seabird nesting sites along the Oregon coast. For each of the 393 sites identified in this catalog, the location, species composition, and abundance of breeding birds are presented. Survey data from 1901 to 2004 are included. Approximately 1.3 million seabirds, representing 15 species, nest in the state (Table 1, Figure 1). This represents approximately half of the seabirds breeding along the west coast of the conterminous United States, including two species (scientific names are in Table 1) of storm-petrels (Leach’s and Fork-tailed), three species of cormorants (Double-crested, Brandt’s, and Pelagic), three species of gulls (Western, Glaucous-winged, and Ring-billed), one tern species (Caspian), and six species of alcids (Common Murre, Pigeon Guillemot, Marbled Murrelet, Cassin’s Auklet, Rhinoceros Auklet, and Tufted Puffin). One shorebird species (Black Oystercatcher) is also included because of its strong affiliation with marine habitats and the high degree of overlap between seabird and Black Oystercatcher nesting sites. Marbled Murrelets nest solitarily in forest habitats distinctly different from other Oregon seabirds, and are not included in this catalog. Readers are referred to Ralph et al. (1995) and McShane et al. (2004) for further information on Marbled Murrelet abundance and nesting distribution in Oregon. This catalog it restricted to seabird species that breed along the coast and in the lower estuaries within Oregon state boundaries. It does not include the millions of marine birds that breed elsewhere and migrate to Oregon’s rich coastal waters, such as albatrosses that nest in the central Pacific, shearwaters from the southern hemisphere, and loons, grebes, sea ducks, and gulls that breed in the arctic or inland colonies. At-sea, these migrant species often outnumber Oregon’s breeding seabirds and, although they are not covered in this catalog, they represent a significant component of Oregon’s marine community. Along the Pacific coast, seabird colony catalogs have been published for Alaska (Sowls et al. 1978), California (Sowls et al. 1980), and Washington (Speich and Wahl 1989). Similar catalogs of colonies in British Columbia, Canada have also been published (Drent and Guiguet 1961, Campbell et al. 1990). The first comprehensive survey of Oregon seabird colonies was conducted in 1979 (Varoujean and Pitman 1980) and a draft catalog was prepared (Pitman et al. 1985), but never published. Another complete survey of Oregon colonies was conducted in 1988. In addition to these comprehensive surveys, numerous other surveys of specific species at specific colonies have been completed, including, since 1988, annual aerial photographic surveys of Brandt’s and Double-crested cormorants and Common Murres (all colonies have been photographed annually and a subsample of the colonies have been counted; see Methods), and a coast-wide survey of cormorant colonies in 2003. This catalog provides a compilation of current and historic seabird colony information. This catalog was designed primarily to provide biologists, resource managers, regulatory agencies, and researchers with the best available data on the size and location of Oregon seabird colonies, in a standardized format. The information compiled here serves as a baseline of recent and historic distribution and abundance of breeding seabirds in the state. In the event of an oil spill or other catastrophic occurrence, this catalog can provide quick reference to concentrations of breeding seabirds. The catalog will also be useful to community planners and members of the general public interested in increasing their understanding of Oregon’s diverse seabird community. Finally, future surveys and monitoring can be planned with a better understanding of the dynamics of seabird breeding biology and colony distribution. Speich and Wahl (1989) noted in the introduction to the Catalog of Washington Seabird Colonies that, from its inception, the catalog was destined to be incomplete. The same is true for all colony catalogs. New surveys are continually underway and reports of historic surveys are often incomplete. Introduction Table 1. Seabirds Breeding Along the Coast of Oregon.

The low, sandy islands in the Columbia River estuary support the largest colonies of Caspian Terns (19,000 breeding birds) and Double-crested Cormorants (26,000 breeding birds) in North America, the largest Western/Glaucous-winged gull colonies in the state (16,000 breeding birds), and the only active breeding colonies of Ring-billed Gulls (400 birds) along the Pacific coast (Figure 2). Loss and changes to estuary islands and artificial habitats in Washington, and movement of birds from outer coast and inland colonies, have likely contributed to the rapid increases in the Columbia River colonies over the past decade. Along the outer coast, the vast majority of Oregon’s seabirds nest within the Oregon Coast National Wildlife Refuge (NWR) Complex. The northern Oregon coastline is composed of grand headlands interspersed with sweeping beaches and estuaries. Headland cliffs and offshore rocks support large numbers of nesting seabirds. The largest colony in the state occurs at Three Arch Rocks NWR, where over 225,000 seabirds of 10 species nest. Most of the state’s Tufted Puffins nest on Finley Rock, a large vegetated island within Three Arch Rocks NWR and on the two northernmost Haystack Rocks within Oregon Islands NWR. The central Oregon coast is dominated by extensive sandy beaches, many of which are within Oregon Dunes National Recreation Area managed by the Bureau of Land Management. Relatively few seabirds nest along this stretch of coastline, and colonies are largely limited to the rocky cliffs and nearshore islands from Depoe Bay to Newport and at Heceta Head/Sea Lion Caves (Figure 3). Some birds (primarily Western/ Glaucous-winged gulls, Double-crested Cormorants and Pigeon Guillemots) nest opportunistically on artificial structures within estuaries and Double-crested Cormorants nest in trees in several locations along the central coast. Southern Oregon is particularly rich in offshore sea stacks and rocky coastline, and more than half of the colonies in the state (203 of 393) are located here. Most of the state’s Leach’s Storm-Petrels nest on a few southern Oregon islands with well established soil and vegetation. Numerically, Common Murres dominate the Oregon seabird community (approximately 685,000 breeding birds). Common Murres constitute more than half of all seabirds nesting in Oregon and greater than 65% of the breeding U. a. californica subspecies, rangewide (Carter et al. 2001). Common Murres nest in extremely dense colonies, typically on the top of islands and sea stacks, and have proven to be important indicators of marine productivity. Leach’s Storm-Petrels are the second most abundant breeding seabird in Oregon, with an estimated 480,000 birds nesting at 21 colonies. The overwhelming majority of Leach’s Storm-Petrels nest on seven small islands off the southern Oregon coast (Saddle Rock, Crook Point Rock, Hunters Island, Goat Island, two rocks off Whaleshead Cove, and an unnamed island in Boardman State Park). Due to their small size, nocturnal activity and burrow nesting habit, estimates of both Leach’s and Fork-tailed storm-petrel colony sizes are difficult to obtain, and estimates are often of low reliability compared to other species. Gulls are the most readily identified seabird by casual visitors to the coast. Western Gulls are the dominant nesting gull species throughout the outer coasts of California and Oregon, and Glaucous-winged Gulls are more common in Washington, but the two species readily hybridize and intermix through central and northern Oregon and along the Washington coast (Scott 1971, Bell 1996). Clear distinction of species is difficult in this area of overlap; therefore, large gulls are listed as Western/Glaucous-winged gulls in this catalog. The largest concentration of nesting gulls is in the Columbia River estuary, where half of the state’s 32,300 Western/Glaucous-winged gulls breed. Ring-billed Gulls also nest in the estuary. Coastal colonies, such as the one at East Sand Island, are rare for Ring-billed Gulls, which typically nests at inland locations. They first colonized the Columbia River estuary in the late 1990s. A list of active colonies for each species is presented in Appendix B, including the most recent accurate or representative estimate of the number of breeding birds at each site.

U.S. Geological Survey (USGS) surveys of Caspian Tern, Western/Glaucous-winged and Ring-billed gull, and Double-crested Cormorant colonies in the Columbia River estuary, 1998 – 2004 (Collis et al. 2002, USGS unpublished data). Oregon Institute of Marine Biology (OIMB) annual surveys of Pelagic Cormorants at “OIMB Cormorant colony,” near Cape Arago, 1973 – 2004 (Jan Hodder, OIMB unpublished data). Historical records from published and unpublished sources. Survey methods vary by species, location, size of colony, logistics, and personnel/organization conducting the surveys. Surveys were conducted from boats, aircraft, ground surveys from remote vantage points, and ground surveys within the colony. In general, four techniques have been employed: (1) counts of nests, either directly or from aerial photographs; (2) counts of adult birds on or around the colony, either directly or from aerial photographs; (3) sampling to estimate burrow density and occupancy rates, combined with estimates of colony area; and, (4) crude estimates of nests, birds, or burrows. In this section, methods used during the 1979 and 1988 statewide surveys, and the methods employed by USFWS from 1966 through 2004, are described. Brief summaries of USGS methods employed in the Columbia River estuary and OIMB methods at the Cape Arago cormorant colony are also included. No attempt is made here to provide detailed descriptions of all methods employed to obtain the data presented in this catalog. Readers are referred to the references listed after each data entry in the tables for specific methods. Boat and Ground Surveys During both coastwide surveys, boat and mainland surveys were conducted of all rocks and mainland colony sites from West Point (north of Tillamook Head) to Florence, and Coos Bay to the California border (Figure 4). The remaining sections of coast are dominated by sandy beaches, with no offshore rocks, and they were not surveyed by boat. During boat surveys, larger rocks were circumnavigated and, if conditions were favorable, surveyors landed and occasionally camped overnight. Brief descriptions of the rocks and islands were recorded, including approximate height, soil, vegetation, and any other salient features that might aid future workers in accurately relocating the sites (Appendix C). The majority of the 1979 survey was conducted from a 4 meter (14 foot) inflatable boat (Zodiac) powered by a 25-hp outboard motor. In 1988, surveys were conducted from 4 – 6 meter (14 – 20 foot) inflatable boats with 30-hp outboard motors. Two or three biologists participated in all boat surveys, using 7 – 10 power binoculars. Data were recorded in notebooks and later transcribed to data sheets and entered into an electronic database. Shore-based Surveys Use of high power spotting telescopes from high, stable vantage points afforded the best views of some colonies. Counts of Tufted Puffins at Haystack Rock (Clatsop County), Bandon rocks, and miscellaneous observations of puffins at other sites were made from shore. Annual colony counts of Pelagic Cormorants, Western Gulls, and Pigeon Guillemots at Yaquina Head were derived from a combination of shore and boat-based surveys. The long-term monitoring of the Pelagic Cormorant colony at Cape Arago by OIMB was conducted from shore. Figure 4. Map of Areas Surveyed by Boat During the 1979 and 1988 Coastwide Seabird Surveys.

From 1966 to 1975, USFWS conducted annual aerial surveys of Common Murre and cormorant (species not identified) colonies along the entire Oregon coast using fixed-winged aircraft. These surveys generally targeted only the larger concentrations of Common Murres, and Brandt’s and Double-crested cormorants, and were not designed to be comprehensive. Visual estimates of colony size were made by a single observer during a one day survey of the entire coast. In 1979, several aerial surveys were conducted (Pitman et al. 1985). On 19 April, 1979, all major colony sites along the coast were photographed from a single-engine Cessna aircraft. Although too early in the season for maximum seabird attendance at colonies, the flight served as an orientation flight to identify colonies. Later in the season four aerial surveys were made from U.S. Coast Guard Sikorsky helicopters. All major colonies, including nearly every Common Murre and Brandt's Cormorant colony, were photographed on at least two occasions. Photographs were taken using 35 mm SLR cameras equipped with 200 mm and 300 mm focal length lenses and ASA 64 and 400 color slide film. Beginning in 1988, the timing of aerial photographic surveys was standardized to facilitate comparison between years (Carter et al. 2001). Small, quiet helicopters (Hughes 500, models D & E) with the doors removed were used to minimize disturbance to the colonies and improve the quality of the photographs. Colony photographs were taken by two photographers using 35 mm cameras. Common Murres, Brandt’s and Double-crested cormorants, and Western/ Glaucous-winged gulls have been counted from these photographs. Aerial photographic surveys of islands in the Columbia River estuary have been conducted by USGS since 1997. See Collis et. al. (2002) for a detailed description of survey methods at these colonies. Methods of Estimation Colony estimates based on direct nest counts provide the most accurate information, and this method was used whenever possible. Virtually all Double-crested, Brandt’s, and Pelagic cormorant estimates were obtained using this method. Western/Glaucous-winged gull estimates (except in the Columbia River estuary) were also derived from nest counts. These species build conspicuous nests which are relatively easy to detect. Direct nest counts were also employed whenever possible to estimate Tufted Puffin breeding numbers, but their burrow-nesting habit made the results less reliable. Estimates based on the total number of adults present on the colony were used for those species whose nests are difficult to find and for species that nest in dense colonies, where it is difficult, or impossible, to distinguish breeding from nonbreeding individuals. Pigeon Guillemots and Black Oystercatchers are often quite conspicuous around nesting colonies, but their actual nest sites are difficult to locate. Estimates presented in this catalog for these two species represent the number of adult birds seen in the vicinity of appropriate nesting habitat, unless otherwise noted. Common Murres and Caspian Terns nest in large, dense colonies. Estimates of colony size for these species were based on counts of adult birds on the colony (from aerial photographs), adjusted by a correction factor, to account for breeding birds away from the colony and non-breeding birds in attendance. Burrow-nesting species were the most difficult to estimate. When possible, colonies were directly sampled to estimate burrow density and occupancy rates. The total area of the colony was then estimated in the field or from aerial photographs. Density of active burrows was combined with estimates of colony area to generate colony estimates. Species-Specific Methods Cormorants Pelagic Cormorants typically nest in small colonies on steep cliffs or artificial structures. Boat- or ground-based surveys were the best means to survey these colonies. The longest time series data set for Pelagic Cormorants in Oregon is from the OIMB Cormorant Colony at Cape Arago. Surveys of this colony have been conducted from shore since 1973 by staff and students from Oregon Institute of Marine Biology (J. Hodder, pers. comm.). Double-crested and Brandt’s cormorants typically nest on broader cliff ledges or the tops of islands or headlands where they can be effectively surveyed using high quality aerial photography. Nests are easily identified and counted from projected slides. Double-crested Cormorants also nest in trees, channel markers, bridges, and other structures where new or small colonies can go undetected, especially during aerial surveys. In some colonies (e.g., Three Arch Rocks, Cape Lookout, and Island Rock), Double-crested and Brandt’s cormorants intermix. Distinction between species can be difficult at these colonies if aerial photographs are not high quality. Combining aerial surveys with ground or boat surveys is often necessary to determine the species composition at these sites. From 1966 to 1975, USFWS conducted annual aerial surveys of the major Brandt’s and Double-crested cormorant colonies along the entire Oregon coast, using fixed-winged aircraft. These surveys, conducted in June or July, were completed in one day and the visual estimates did not identify cormorants to species. Beginning in 1979, aerial photographs were utilized in conjunction with ground and boat-based surveys. Since 1988, timing of the surveys has been standardized to coincide with the two-day aerial survey of Common Murres flown annually in early June. (See Common Murre methods for specifics regarding aircraft and photography.) Statewide surveys of all Double-crested, Brandt’s, and Pelagic cormorant colonies were conducted in 1979, 1988, and 2003. Between 1988 and 2003 (except 1995), almost all Brandt’s and Double-crested cormorant colonies were photographed annually, and a sample of 25 colonies was counted each year. Photographs of the other colonies were labeled and archived, but not counted. Brandt’s and Double-crested cormorants exhibit relatively low site fidelity. For surveys of the entire coast, this was not an issue since all colonies were counted and most movement between colonies was captured. However, monitoring trends of single colonies, or small groups of colonies, can lead to erroneous conclusions if birds move between sampled and un-sampled colonies. Common Murre In Oregon, Common Murres nest on the tops of islands or on mainland cliffs in large, dense colonies. Common Murres do not build nests, and colony estimates are based on counts of adult birds on the colony. From 1966 to 1979, Common Murre colonies were surveyed by visual estimates of breeding birds from a fixed wing airplane. Given the high densities and large size of Oregon Common Murre colonies, these estimates were generally very poor quality. Counts from aerial photographs were first used in 1979 (Pitman et al. 1985), however; biologists had limited control over the timing of the surveys and many of the photographs were taken too late in the season to accurately census breeding murres. Since 1988, single annual aerial photographic surveys of all major Common Murre colonies in Oregon have been conducted (except 1995) using standardized techniques. Surveys were flown in early June to coincide with late incubation and hatching (after Takekawa et al. 1990), using a Hughes 500 helicopter (models C, D and E) or a Bell helicopter at altitudes of 260 – 330 m with side doors removed. Colony photographs were taken by two photographers using 35-mm cameras with 100 – 400 or 300 mm lenses for close-up photographs (front-seat photographer) using ASA 400 color slide film and shutter speeds less than 1/1000 per second, and 55- or 70 – 210-mm lenses for colony overviews (back-seat photographer) (Carter et al. 2001). Overlapping colony slides were projected onto large sheets of paper, simultaneously using 3 – 4 projectors, and individual birds were counted. These data were transferred to data sheets and computerized. A general k-correction factor of 1.67 (based on California data) was applied to all count data to estimate the number of breeding adults at colonies in Oregon (Carter et al. 2001). A specific k-correction value for Oregon colonies has not been researched. All Common Murre colonies were photographed annually between 1988 and 2004, and a subsample of 31 colonies was counted annually. Photographs of the other colonies were labeled and archived. In the data tables of this catalog, the actual counts of Common Murre adults and the estimated number of breeding birds (bird count x 1.67) are both reported. Pigeon Guillemot Pigeon Guillemots nest in rock crevices and burrows, and nests are extremely difficult to locate and count. Pigeon Guillemots are social birds and they gather on the rocks and in the water adjacent to nesting areas early in the season. Repeated counts of Pigeon Guillemots on the water during early morning or evening in late April and May show little daily variation and presumably represent an index of the nesting population (Ainley et al. 1990). Counts generally decrease by late morning and are lower through the middle of the day (Carter et al. 1992). Counts also tend to be lower later in the season, since one pair member is incubating or both members are foraging more actively during the chick-rearing period. Counts presented in this catalog were not standardized for time of season or time of day, so colony sizes were likely underestimated. Counts of Pigeon Guillemots during El Nino years might be higher than expected if few birds are nesting and more are visible on the water near the colony (Jaques and Strong 2001). Tufted Puffin Tufted Puffins can be counted outside nesting burrows early in the season, particularly during the morning hours. Unlike Pigeon Guillemots, Tufted Puffins engage in frequent flights, entries and departures from burrows, and exhibit variable activity levels through the day, confounding any attempt to get an index of the breeding population based on a count of adults. Estimates were typically derived from a ground count of appropriately sized burrows (often obtained after Methods 13 14 Catalog of Oregon Seabird Colonies the nesting season on islands with nesting Common Murres). At some colonies, the presence of Tufted Puffins was noted and a rough estimate was generated based on the number of sightings and the amount of suitable nesting habitat. Small Nocturnal Burrow-Nesting Species Fork-tailed and Leach’s storm-petrels, and Rhinoceros and Cassin’s auklets are nocturnal burrow nesters, and estimates of colony size are particularly difficult to obtain. Estimates of colony size are of poor quality; far less precise than for surface nesters, and may only be accurate within an order of magnitude except where intensive surveys were conducted. Only a few Oregon islands have soil of sufficient depth to support burrow nesting. Observations from a remote vantage point are not possible, even for Rhinoceros Auklets that are active at dusk. The rugged nature of Oregon’s islands and the presence of breeding murres at many sites precludes ground surveys of most of the islands. Estimates of Cassin's and Rhinoceros auklet colonies were based on observations of birds close to the colony (often "staging" at dusk) or the availability of suitable nesting habitat. Only a few estimates were based on visits to the colonies during the nesting season. In 1979 and 1988, estimates of Leach's Storm-Petrel numbers at Goat Island, Hunters Island, and Saddle Rock were derived from density estimates of burrows in specific nesting habitat types, coupled with an estimate of the total area of each habitat type. In 1979, rough estimates of breeding Leach’s Storm-Petrels were also generated for islands where breeding was known to occur, but which were surveyed only briefly or not at all. At these islands, the area of potential nesting habitat was visually estimated and density estimates from Goat Island (2.4 breeding birds/m2) were applied to calculate a rough estimate of the potential Leach's Storm-Petrel breeding population. In 1988, presence or absence of Leach’s Storm-Petrels was noted for colonies that could not be surveyed on the ground, but numerical estimates of colony size were not made for these colonies. Thousands of Leach’s Storm-Petrels have been banded at Saddle Rock in southern Oregon between 1979 and 2004, and mark-recapture techniques are being investigated as a monitoring tool at this colony. Western and Glaucous-winged Gulls and Hybrids Western/Glaucous-winged gulls are opportunistic in selection of nesting substrate and habitats. They nest on a variety of structures (roof tops, pilings, bridges, islets) and small colonies can be missed. A combination of boat, ground, and aerial surveys were used to count Western/Glaucous-winged gull nests at various sites during the two statewide surveys. Annual aerial photographic surveys were conducted by USGS at the East Sand Island colony in the Columbia River in 1997 and 1998 (Collis et al. 2002). Since 1999, aerial photographs have been taken and archived (D. Roby, pers. comm.). Counts of nests were the basis for colony estimates at all sites except colonies in the Columbia River estuary, where adults were counted from aerial photographs. A specific k-correction factor has not been researched for the estuary colonies (the largest concentration of nesting gulls in Oregon), so the k-value of 1.4, calculated for Western Gulls in California (Carter et al. 1992), was substituted. Both the actual count of birds and the estimated number of breeding birds at these colonies are presented in the data tables. Oregon is in the zone of hybridization between Western and Glaucous-winged gulls (Scott 1971, Hoffman 1978, Bell 1996). While hybridization between these species occurs as far south as central California, most nesting gulls on the southern and central Oregon coast are Western Gulls (Bell 1996, D. Pitkin, pers. comm.). In 1989, Bell (1996) found that approximately half of the gulls nesting in the Columbia River estuary were Glaucous-winged or hybrids. These Columbia River colonies have increased in size by an order of magnitude since 1989, and the proportion of hybrids appears to have increased also. Determination of hybrid status is impossible from the air. All estimates in this catalog are reported as Western/Glaucous-winged gull, but the proportion of Western Gulls, Glaucous-winged Gulls, and hybrids varies at each site. Caspian Tern Aerial photographic surveys of Caspian Tern colonies in the Columbia River estuary have been conducted annually by USGS since 1997 (Collis et al. 2002). Intensive ground surveys of Caspian Tern plots were conducted each year in conjunction with the aerial surveys to generate k-correction factors which were then applied to bird counts to estimate the number of breeding birds. See Collis et al. (2002) for a more detailed description of survey methods at these colonies. Maps and Data Tables How to Use This Catalog The following section consists of maps denoting the location of each seabird colony and accompanying tables with recent and historical estimates of the number of breeding birds, for each species, at each colony. Figure 5 presents an example of a data table with an explanation of the columns and the codes. Colony Numbers and Names Oregon seabird colonies were assigned unique identifying numbers during the 1988 statewide survey, according to the numbering convention used for the California and Washington seabird colony catalogs (Sowls et al. 1980, Speich and Wahl 1989). The Oregon coast was divided into five areas delineated by degree of latitude and corresponding to USGS 1:250,000 topographic maps (Figure 6). These USGS maps were sequentially numbered for the conterminous United States as the basis for a standardized colony numbering system for waterbirds (Spendelow and Patton 1988). Within each map area, colonies were numbered north to south with the first three digits designating the map, and the next three digits representing the site number, beginning with 001. When new colonies were discovered following the initial number designation in 1988, they were given a decimal extension of the number of the nearest original colony. For example, 219-001.1 was a colony discovered after 1988 adjacent to colony 219-001. Colony names were derived from maps or charts whenever possible. If a location did not have an official name and a descriptive name was assigned by a surveyor, then this name is reported in quotes to indicate that it cannot be found on maps. All other colonies were labeled “Unnamed Colony” and the colony number is the identifier. Most Recent or Representative Estimate The data tables contain all of the recent and historic estimates of colony size. The most recent, accurate or representative (MRA) estimate for each species is presented at the top of the table in a box. MRA data were used to generate total statewide estimates for each species. For most species and most colonies, MRA data were the most recent estimates. However, if the most recent estimate was poor quality (e.g., non-quantitative estimate such as “present”) and an earlier, quantitative estimate of higher quality was available, then the earlier estimate was presented in the MRA box at the top of the table and the more recent estimates were presented below. If the most recent data were collected during an El Niño year, or were otherwise not representative of the numbers of birds that typically nest at a particular colony, then these data were presented in the table but the most recent “representative data” were presented in the MRA box at the top of the table. (El Niño events affected Oregon in 1993 and 1997 and estimates from these years are not presented in the MRA box.) Another situation where the most recent data were not the most representative data involved Common Murre and Double-crested and Brandt’s cormorant colonies harassed by Bald Eagles (Haliaeetus leucocephalus). Bald Eagles have increased along the Oregon coast, and harassment of colonies, especially in the northern section of the state, has resulted in nesting failure and early abandonment of some colonies prior to early June, when aerial surveys normally occur. In a few instances, estimates from a previous year that were more representative of the number of birds at a given colony were presented in the MRA box at the top of the table. Data Codes Presented below is an accounting of the codes utilized in the data tables (Figure 5). Latitude/Longitude.—Geographic coordinates for each colony are presented in degrees, minutes, and seconds. Coordinates are for the center point of onshore colonies, and the centroid of individual island colonies or groups of offshore rocks/islands that constitute a single colony.

Code Description B Birds: Count or estimate of individual birds in colony. N Nests or burrows: Count or estimate of nests or burrows in colony. O No count or estimate: Observer provided no quantitative estimate of colony size, only non-numeric data like 'Present' or 'Rare'. U Unknown: Unexplained how the number was generated Conversion (Cnv).—This code describes how the count or survey data were adjusted to generate estimates of breeding birds. Counts of nests were multiplied by 2 and counts of birds were often adjusted by a k-conversion factor to account for non-breeding birds at the colony and breeding birds away from the colony. These codes are the same as those used for the North Pacific Seabird Colony Database (USFWS 2004). Code Description L Literal count or estimate reported by observers; no adjustment 2 Counts of nests were multiplied by 2 to estimate the number of breeding birds 1.67 Counts of Common Murre adults were multiplied by 1.67 to estimate breeding birds. #.## Conversion factors for some species were calculated at the time of the surveys and therefore vary by year (e.g., Caspian Terns at East Sand Island). The numeric value is the k-factor used to adjust the count data. A Midpoint of range (e.g., 500-1000 entered as 750) S Extrapolation of data from sampling (e.g., burrow densities in sample quadrats) Survey Type (ST).—Survey method used to census or survey the colony. Codes were sometimes combined to indicate that more than one method was used (e.g., B,M for boat and mainland coverage of Yaquina Head). Code Description A Aerial survey from fixed-wing airplane or helicopter AP Aerial photography B Boat M Mainland—Ground survey from a remote mainland vantage point C Colony—Ground survey in the colony or on the island U Unknown Estimate Type (T).—Type of estimate or count made by the observer. Codes may be qualitative or quantitative. These codes are the same as those used for the North Pacific Seabird Colony Database (USFWS 2004). Code Description W Actual count of each bird, pair, or nest in colony S Sampled; count of birds or nests in a known area extrapolated to entire colony area Z Part estimated, part counted: exact count of a portion of the colony; remainder of the colony estimated T Count by groups: count of birds, pairs, or nests by groups (e.g., 10s or 1000s) Y Estimate, not an actual count: observer estimated birds, nests, or pairs by some method. Observer did not make an exact count of individuals or groups, but numbers were provided (e.g., "500 to 1000" or "thousands") X Present: observer reported breeding birds of this species at the colony, but no estimate of numbers P Probable: observer reported breeding birds probably present at colony, but no estimate of numbers U Type of estimate unknown: census method or accuracy of method unknown (observer did not describe method well) Data Quality (Q).—This code describes how accurately the data reflects the actual number of breeding birds of each species in the colony. Data quality can be affected by many factors such as survey conditions, biology of the species, and methods employed. Code Description 1 A direct count of all nests in a colony (onsite or aerial photograph) or a precise estimate of the number of breeding birds. Examples of data of this quality include aerial photo surveys of cormorant nests or counts of gull nests from boat or shore. These data can be used to detect annual change in colony size. 2 A direct count of adult birds at a colony with quantification of the number of nests (or breeding pairs) represented by adults at the colony (a k-correction factor), or repeated counts of birds using standardized techniques. Examples of quality data 2 include aerial photo surveys of Caspian Terns and Double-crested Cormorants at the Columbia River colonies; aerial photo surveys of Common Murre colonies; and, repeated, standardized surveys of Pigeon Guillemots. Changes in number of birds and long-term trends can be detected using data of this quality. 3 A count or estimate of adults birds at or near a colony, where k-correction factors are not available. Examples of data quality 3 include single surveys of Pigeon Guillemots or Tufted Puffins, or nest counts where only a portion of the nests are visible. 4 A rough estimate of colony size that is only reliable within an order of magnitude, at best. Examples of data quality 4 include presence/absence observations, or rough visual estimates of colony size (e.g., ‘hundreds’, or ‘several thousand’), or most estimates of nocturnal burrow-nesting species. These data are of limited value and should only be used to document extremely large changes in colony size. Maps and Data Tables 19 20 Catalog of Oregon Seabird Colonies Ainley, D. G., R. J.
