FamilyHawks and Eagles

HabitatCoasts, rivers, large lakes; in migration, also mountains, open country. Typically close to water, also locally in open dry country. Occurs in a variety of waterside settings where prey is abundant, including swamps in Florida, edges of conifer forest in southeastern Alaska, treeless islands in Aleutians, desert rivers in Arizona. Also winters in some very dry western valleys.

The emblem bird of the United States, majestic in its appearance. It is not always so majestic in habits: it often feeds on carrion, including dead fish washed up on shore, and it steals food from Ospreys and other smaller birds. At other times, however, it is a powerful predator. Seriously declining during much of the 20th century, the Bald Eagle has made a comeback in many areas since the 1970s. Big concentrations can be found wintering along rivers or reservoirs in some areas.

 

Feeding Behavior

Opportunistic; sometimes a predator, sometimes a scavenger. Does much hunting by watching from a high perch, then swooping down to catch prey in its talons. Also hunts by cruising very low over sea or land, taking prey by surprise. Where fish are abundant (as at spawning runs), may wade in shallow water to pursue them. Sometimes steals fish from Ospreys or other birds. Also lands on ground to feed on carrion.

 

 

Eggs

2, sometimes 1-3. White. Incubation is by both parents, 34-36 days.

 

 

Young

At least one parent remains with young almost constantly for first 2 weeks. Both parents bring prey to nest, tearing food into small pieces and feeding it directly to young at first; after 3-6 weeks, young begin pecking at food dropped in nest. In seasons when prey is scarce, only largest young may survive. Age at first flight about 10-12 weeks.

 

Diet

Mostly fish when available, also birds, mammals. Feeds heavily on fish in many areas, including herring, salmon, carp, catfish, many others. When fish are scarce, may eat birds (ducks, coots, auklets, others) or mammals (jackrabbits, muskrats, others). Sometimes eats turtles, crabs, shellfish, other items. Often feeds on carrion; when fish or carrion readily available, may catch few birds or mammals.

 

 

Nesting

Usually first breeds at age 4-5 years, and may mate for life. Nest site is usually in tree, often on cliff in west, or on ground on northern islands. Tree nests are usually in very tall tree, standing above surrounding forest, up to 180' or more above ground. Nest (built by both sexes) usually a mound of sticks, lined with finer materials; nest may be reused and added to for years, becoming huge. Great Horned Owls sometimes take over nests.
