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.
セキセイインコ
Open grasslands, scrublands, and woodland in the Australian interior. Nomadic, following rainfall and seeding events.
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.
セキセイインコ
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.
Geographic Range & Migration
ハクトウワシ
North America from Alaska and Canada through the contiguous United States to northern Mexico.
セキセイインコ
Interior of Australia, especially arid and semi-arid regions. One of the most popular pet birds worldwide.
