About These Birds

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.

It inhabits humid lowland tropical forests of Amazonia, occurring in Brazil, Peru, Colombia, and adjacent countries.
