About These Birds
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.
Northern Cardinal
The northern cardinal is the state bird of seven US states, more than any other species. Unlike many songbirds, both males and females sing, often in duets. Cardinals do not migrate and their brilliant red plumage against winter snow makes them a favorite among backyard birdwatchers.
