This weekend is the Great Backyard Bird Count. Its a fantastic way to tell people what birds are in your area. Go out. Count the birds. Come back inside. Enter them online. Compare your results with what others are seeing in your area and around the country. Very cool. And if you like it, you can do it all year round on Ebird.
This morning I entered the birds I saw as I was leaving my house in Sellersville, PA (2 Canada Goose and 1 American Crow) and 10 species I'm seeing at the feeders here in Ivyland, PA. Nothing spectacular, but every data point adds to our understanding of local, regional, and continental bird distribution. And its great fun!
The Great Backyard Bird Count and Ebird are joint projects of the National Audubon Society and Cornell Laboratory of Ornithology.
