Song & Call Comparison

High-pitched, chattering whistle: a rapid 'kleek-kik-ik-ik-ik'. Surprisingly weak and thin for such a large raptor. Also gives a lower 'kwit-kwit' call near the nest.
Perruche ondulée
A rising, chattering 'budgerigar' chatter: rapid series of 'chek-chek-chek' and melodic warbling. Enormous wild flocks produce a continuous roaring chorus. Good vocal mimics in captivity.

About These Birds
pygargue à tête blanche
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.
