Song & Call Comparison
Белоголовый орлан
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.
Eurasian Wren
Extraordinarily loud for its tiny size: a rapid, powerful stream of trills, buzzes, and churring phrases. One of Europe's loudest songs by volume relative to body weight.
Geographic Range & Migration

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.
Eurasian Wren
The Eurasian wren is one of the smallest birds in Europe but possesses an astonishingly loud song for its size. Males build multiple dome-shaped nests, from which the female selects one to line and use. In British folklore, the wren is known as the king of birds for outwitting the eagle in a flying contest.
