Christmas Bird Count
National Audubon Society
- December 1–January 31
This is an ongoing Citizen Science Experience. Contact the sponsoring organization to join in.
At the annual Christmas Bird Count, birdwatchers brave cold temperatures and all weather conditions to survey birds in a designated “count circle” on a given day. A count’s survey area stays the same from year to year, comprising a circle fifteen miles in diameter around a central point. International in scope, the Christmas Bird Count is organized and compiled by the National Audubon Society, who coordinates all count circles so they don’t overlap.
