�ԹϺ���

NEW YORK (December 14, 2025) — The �ԹϺ��� invites bird lovers and community scientists across the Western Hemisphere to participate in the 126th annual �ԹϺ��� Christmas Bird Count, taking place December 14 through January 5. More than 2,800 count circles from Canada to Chile will gather important data to inform conservation strategies and help protect birds in a rapidly changing climate.  

“�ԹϺ���’s Christmas Bird Count is one of our most important traditions and a wonderful opportunity for people to gather in the name of conservation,” said Dr. Elizabeth Gray, CEO of the �ԹϺ���. "For 126 years, participating in the Christmas Bird Count has been a meaningful way to spend time outdoors while contributing to vital conservation science.”

Each count takes place in a 15-mile-wide circle and is led by a compiler responsible for safely organizing volunteers and submitting observations directly to �ԹϺ���. Within each circle, participants tally all birds seen or heard that day — not just the species but also total numbers to provide a clear idea of the health of that particular population.  

When combined with other surveys like the Breeding Bird Survey, �ԹϺ���’s Christmas Bird Count helps provide a picture of how bird populations have changed over the past century, a long-term perspective that is critical for protecting birds and their habitat. These data have been cited in more than 300 peer-reviewed articles, including a 2019 study in Science that documented the loss of nearly three billion North American birds since 1970. 

The count is also used to measure how birds are responding to climate change. A 2022 �ԹϺ��� study used 90 years of Christmas Bird Count data to show how bird ranges have shifted over time, helping prioritize conservation efforts in areas that are important for birds today and in a climate-altered future. With two-thirds of North American bird species at increasing risk of extinction by the end of this century, the data are more important than ever.

“�ԹϺ���’s Christmas Bird Count allows community scientists to join a legacy of more than twelve decades of conservation,” said Dr. Ben Haywood, �ԹϺ���’s director of community science. “Adding to such a long-term dataset helps conservation scientists better understand the state of the birds and how we can improve our efforts to protect them and the places they need.” 

The first count circles were located in 25 locations across the United States and Canada. The program has since expanded to more than 2,800 circles across the United States, Canada, Latin America, the Caribbean and the Pacific Islands. Last year’s 125th �ԹϺ��� Christmas Bird Count included 35 species in newly established circles in Peru that had not previously been encountered. In the United States, participants also observed “late lingerers” such as Black-and-white Warblers, which normally spend the winter in the tropics, staying in the United States due to a milder winter.  

There is no fee to participate in the �ԹϺ��� Christmas Bird Count. To sign up, find the circle nearest you and register with your local compiler at . All data must be submitted through the official compiler to be added to the census.
