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.
Белоголовый орлан
The bald eagle is the national bird and symbol of the United States. Once endangered due to DDT pesticide use, it made a remarkable recovery and was removed from the endangered species list in 2007. These powerful raptors build the largest tree nests of any bird, some weighing over two tons.
