Large bodies of open water including coasts, rivers, and lakes with abundant fish and old-growth trees for nesting.

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.
虎皮鸚鵡
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
白头海雕
North America from Alaska and Canada through the contiguous United States to northern Mexico.
虎皮鸚鵡
Interior of Australia, especially arid and semi-arid regions. One of the most popular pet birds worldwide.

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.
虎皮鸚鵡
The budgerigar is the third most popular pet in the world after dogs and cats, and by far the most common pet parrot. Wild budgies travel in enormous nomadic flocks that can darken the sky. Males can learn to mimic human speech, with one record-holding budgie having a vocabulary of 1,728 words.
