About These Birds
American Crow
The American crow is one of North America's most familiar and intelligent birds. Research has shown they can recognize individual human faces and communicate perceived threats to other crows. They form large winter roosts of up to hundreds of thousands of individuals in some cities.
Common Nightingale
The common nightingale is celebrated as one of the finest songsters in the bird world, inspiring poets from Homer to Keats. Males sing complex phrases of over 250 different types, often at night during breeding season. Despite its famous song, the nightingale is a plain-looking bird that skulks in dense vegetation.
