Every winter for more than 50 years, volunteers have scoured a 15-mile diameter circle in the Peterborough-Hancock area for birds as part of the Christmas Bird Count (CBC) – the largest and longest-running community science project in the world. In addition to the teams who fan out in the field, birds are also tallied at backyard feeders.
