Large bodies of open water including coasts, rivers, and lakes with abundant fish and old-growth trees for nesting.

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.
European Robin
Exquisite, melancholic melody of thin whistled phrases, rising and falling softly. Rich, warbling song year-round; both sexes sing. Alarm call is a sharp 'tic-tic-tic'.
Geographic Range & Migration
白头海雕
North America from Alaska and Canada through the contiguous United States to northern Mexico.
European Robin
Europe, western Asia, and parts of North Africa. Northern populations migrate south in winter; western European populations are largely resident.

About These Birds
白头海雕
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.
