The free event, hosted by Audubon, Cornell Lab of Ornithology, and Canadian partner Bird Studies Canada, is open to anyone and no registration is needed. Watch and count birds for at least 15 minutes on any day of the count. Your results are entered by you at www.birdcount.org and provide a snapshot of the whereabouts of more than 600 bird species. - Learn more about how you can participate at a local National Wildlife Refuge, nature center, city park, school yard or your own backyard!
