Great Backyard Bird Count
Great Backyard Bird CountMid-FebruaryThe Great Backyard Bird Count takes place every year over four days in mid-February throughout the United States and Canada. Volunteers of all ages and experience, known as "citizen scientists," spend at least 15 minutes counting birds from any location—their home, a park, or a schoolyard. Then they report the number of birds and species they have seen via the Internet. This gives scientists a real-time portrait of which birds are where in North America. The event was launched in 1998 by the National Audubon Society and the Cornell University Ornithology Lab. In 2007, participants submitted more than 80,000 checklists, reporting 11 million birds of 616 different species. The web site of the Great Backyard Bird Count allows participants to track data, get tips on identifying birds, and enter count-related contests.
