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.
Great Cormorant
Coasts, estuaries, lakes, rivers, and reservoirs. Nests in colonies in trees, on cliffs, or on the ground.
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.
Great Cormorant
Deep, guttural grunts and 'karrr' calls at colonies. Bill-clicking and hissing in threat displays. Silent at sea. Colonial noise can be deafening during the breeding season.
Geographic Range & Migration
bald eagle
North America from Alaska and Canada through the contiguous United States to northern Mexico.
Great Cormorant
Very wide range across Europe, Asia, Africa, and Australasia. One of the most widespread cormorant species.

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.
Great Cormorant
The great cormorant is one of the most widespread seabirds in the world. Unlike most waterbirds, cormorants lack fully waterproof plumage, leading to the iconic pose of standing with wings spread open to dry. In Asia, cormorants have been used by fishermen to catch fish for over a thousand years.
