Size Comparison
Habitat Comparison
ハクトウワシ
Large bodies of open water including coasts, rivers, and lakes with abundant fish and old-growth trees for nesting.
Emu
Open grasslands, savanna woodlands, scrublands, and semi-arid plains across Australia. Avoids dense forest and true desert.
Song & Call Comparison
ハクトウワシ
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
ハクトウワシ
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.
