Size Comparison
Habitat Comparison

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

Open grasslands, savanna woodlands, scrublands, and semi-arid plains across Australia. Avoids dense forest and true desert.
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.
Emu
Deep, resonant booming grunt 'e-moo', often repeated 3 times. Females give a deep drumming call produced by an inflatable throat pouch. Generally low-pitched and far-carrying.
Geographic Range & Migration
Белоголовый орлан
North America from Alaska and Canada through the contiguous United States to northern Mexico.
Emu
Throughout mainland Australia. Absent from Tasmania, where the Tasmanian emu was driven to extinction by 1850.

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.
Emu
The emu is the second-tallest living bird and the largest bird native to Australia. It is the only bird with calf muscles, enabling powerful running at up to 50 km/h. In the famous Emu War of 1932, the Australian military was deployed against crop-raiding emus — and the emus arguably won.
