Size Comparison
Habitat Comparison
bald eagle
Large bodies of open water including coasts, rivers, and lakes with abundant fish and old-growth trees for nesting.
Eastern Bluebird
Open woodland, farmland edges, orchards, and parks with scattered trees and open ground. Readily uses nest boxes.
Song & Call Comparison
bald eagle
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.
Eastern Bluebird
A rich, melodious warbled 'chur-wi, tur-a-lee' song. Both sexes sing. Call is a soft, musical 'turee'. Song is gentle and flute-like, suggesting a small thrush. Given from exposed perch.
Geographic Range & Migration
bald eagle
North America from Alaska and Canada through the contiguous United States to northern Mexico.
Eastern Bluebird
Eastern North America from southern Canada to Honduras and Nicaragua. Partially migratory.

About These Birds
bald eagle
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.
Eastern Bluebird
The eastern bluebird is a beloved symbol of happiness in North America. Once declining due to habitat loss and competition from introduced species, populations recovered dramatically thanks to a massive citizen science nest box campaign. These gentle thrushes form loose winter flocks and huddle together in nest boxes during cold snaps.
