Large bodies of open water including coasts, rivers, and lakes with abundant fish and old-growth trees for nesting.
Wandering Albatross
Open ocean of the Southern Hemisphere. Breeds on remote sub-Antarctic islands. Spends years at sea between breeding attempts.
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.
Wandering Albatross
At nesting colonies emits a loud braying 'waaah' and guttural grunts. Silent at sea for most of the year. Courtship involves ritualized mutual bill-clapping and moaning calls.
Geographic Range & Migration
ハクトウワシ
North America from Alaska and Canada through the contiguous United States to northern Mexico.
Wandering Albatross
Southern Ocean circumpolar, breeding on South Georgia, Crozet, Kerguelen, and other sub-Antarctic islands.
