Learning About Birds!

The Bird Identification InfoCenter presents photographs, songs, videos, identification tips, maps, and life history information for North American birds.

The Bird Identification tips webpages provide tools for learning about birds.

The Patuxent Bird Quiz lets you test your knowledge of North American bird identification, distribution in winter (from the Audubon Christmas Bird Count) and summer (from the North American Breeding Bird Survey), and song. Note that we use the term "song" loosely, here, and that you might have look pretty hard to see some of the photographed bird species in North America!
