Hiçbiri
Kel kartal
Large bodies of open water including coasts, rivers, and lakes with abundant fish and old-growth trees for nesting.
Northern Gannet
Open ocean and coastal waters. Breeds in dense colonies on steep rocky islands and sea stacks.
Song & Call Comparison
Kel kartal
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.
Northern Gannet
Loud, harsh 'urrah-urrah' grunting and croaking at breeding colonies on sea stacks. Also gives a softer 'karrr' in flight. Large colonies are extremely noisy during the breeding season.
Geographic Range & Migration
Kel kartal
North America from Alaska and Canada through the contiguous United States to northern Mexico.
Northern Gannet
North Atlantic, breeding from Newfoundland and Gulf of St. Lawrence to Norway, Iceland, and Britain. Winters at sea south to the tropics.

About These Birds
Kel kartal
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.
Northern Gannet
The northern gannet is a spectacular plunge-diver, folding its two-meter wingspan into an arrow shape to hit the water at up to 100 km/h. Air sacs under the skin and a reinforced skull protect it from the impact. Bass Rock in Scotland hosts over 150,000 gannets, the largest single colony of any seabird in the world.
