It’s time for the annual Christmas Bird Count (CBC)! There are 21 active counts across New Hampshire, and all interested birders are welcome to join.
Check the list below for a count near you and contact the compiler listed if you’d like to participate. Each count takes place within a designated count circle (a 15-mile diameter area centered on a specific point). The circle is divided into sections, with teams assigned to survey each one. If you live inside a count circle, you can even contribute by counting the birds in your own backyard!
The Christmas Bird Count is an international effort organized by the National Audubon Society, which coordinates all circles to ensure they don’t overlap. Each local count selects one survey day between December 14 and January 5.
While NH Audubon does not coordinate the CBC, we’re pleased to share this list of New Hampshire compilers and count dates so you can find a circle near you and join the fun.
Be part of a more than 100-year-old winter tradition. Bundle up, grab your binoculars, and help count New Hampshire’s winter birds!
(Note: Please note these dates were for the 2025 CBC. Updated dates will be posted in November 2026.)
