Bald Eagle (Haliaeetus leucocephalus)
General Information
Blackish-brown back and breast; a white head, neck, and tail; and
yellow feet and beak. Juvenile bald eagles are a mixture of brown
and white; with a black bill in young birds. The adult plumage
develops when they're sexually mature. It takes about 5 years for
their head and tail feathers to gradually turn white. The bald eagle
is the only eagle confined to North America, and there are no other
large black birds in North America with white heads and tails.
The female bald eagle is 35 to 37 inches, slightly larger than the
male. With a wingspan which varies from 79 to 90 inches. The male
bald eagle has a body length from 30 to 34 inches. The wingspan
ranges from 72 to 85 inches. Bald eagles weigh from ten to fourteen
pounds. Northern birds are significantly larger than their southern
relatives.
The golden eagle is larger than the bald eagle in average height and
wingspan, but there isn't much difference in their average weight.
Habitat and Range
The Bald Eagle prefers habitats near seacoasts, rivers, large lakes,
and other large bodies of open water with an abundance of warm-water
fishes. Studies have shown a preference for bodies of water with a
circumference greater than 11 km (7 mi), and lakes with an area
greater than 10 sq km (3.8 square miles) are optimal for breeding
bald eagles, although longer and narrower bodies of water can
support breeding pairs.
The Bald Eagle's natural range covers most of North America,
including most of Canada, all of the continental United States, and
northern Mexico. The bird itself is able to live in most of North
America's varied habitats from the bayous of Louisiana to the
Sonoran desert and the eastern deciduous forests of Quebec and New
England. It can be a migratory bird but it also is not unheard of
for a nesting pair to overwinter in its breeding area.
