Size Comparison
Habitat Comparison
白头海雕
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
白头海雕
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
白头海雕
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.

About These Birds
白头海雕
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.
Wandering Albatross
The wandering albatross has the largest wingspan of any living bird, reaching up to 3.5 meters. These oceanic nomads can circumnavigate the globe, covering over 120,000 km per year using dynamic soaring with minimal wing flapping. Pairs mate for life and may live over 60 years.
