Potsdam, NY, Feb 10, 2010 — Thousands of bird watchers will take part in the annual Great Backyard Bird Count this weekend. Volunteers will count birds in their own backyards, local parks and wildlife refuges. The "citizen scientist" project helps track late-winter bird populations across North America. It also helps monitor how birds are responding to environmental change. Todd Moe spoke with birder Joan Collins, who is a member of Northern New York Audubon. She says it's been a quiet winter at the local bird feeder.
