The Audubon Christmas Bird Count
Citizen Science in Action

Red-tailed Hawk gets
counted!

The Audubon Christmas Bird Count, a tradition first proposed by ornithologist Frank M. Chapman on Christmas Day 1900, is the nation's longest-running citizen-science bird project. New York City Audubon plays its part in this annual bird population survey, which is now conducted across North America, Latin America, the Caribbean, Bermuda, and the Pacific Islands. The data collected by observers over the past century allow researchers, conservation biologists, and other interested individuals to study the long-term health and status of bird populations across North America.

The 116th annual Audubon Christmas Bird Count has now ended. NYC Audubon is responsible for reporting data for the Lower Hudson Count Circle, which includes all of Manhattan and parts of New Jersey. And we host Manhattan's Central Park compilation gathering at the Central Park Arsenal each year, a festive event! This year's Lower Hudson Count took place on Sunday, December 20, 2015. A summary of the count can be found here, and results from 2015 and earlier can be downloaded by clicking the links below.

Next year’s Lower Hudson count will take place on Sunday, December 18, 2016.
