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.

Open woodland, orchards, gardens, parks, and weedy fields with seed-bearing plants. Common at garden bird feeders.
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.
European Goldfinch
A liquid, tinkling 'swit-swit-swit' in flight and a melodic twittering song. Flocks produce a bright jingling chorus. Male song is a sweet repetitive warble incorporating the flight call.
Geographic Range & Migration
白头海雕
North America from Alaska and Canada through the contiguous United States to northern Mexico.
European Goldfinch
Europe, North Africa, and western Asia. Introduced to Australia, New Zealand, and parts of South America.

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.
European Goldfinch
The European goldfinch is a strikingly beautiful finch whose tinkling song and colorful plumage have made it popular in art and as a caged bird for centuries. It appears frequently in Renaissance paintings as a symbol of the Passion of Christ. Flocks of goldfinches are charmingly called a charm.
