The bald eagle is a bird of prey found in North America. A sea eagle, it has two known subspecies and forms a species pair with the white-tailed eagle, which occupies the same niche as the bald eagle in the Palearctic. Its range includes most of Canada and Alaska, all of the contiguous United States, and northern Mexico. It is found near large bodies of open water with an abundant food supply and old-growth trees for nesting.

North America
Typical Environment
Bald eagles occur from Alaska and Canada through most of the contiguous United States and into northern Mexico. They are most common near coasts, large lakes, reservoirs, and major rivers with ample fish and suitable tall trees or cliffs for nesting. Winter concentrations form where water remains unfrozen and food is abundant. They use both pristine and human-altered landscapes if foraging and nesting needs are met. In migration and winter they gather at salmon runs, waterfowl staging areas, and open-water leads.

Despite the name, it isn’t bald—the term refers to the white, “piebald” head. It is the national bird and symbol of the United States and rebounded dramatically after DDT bans and conservation actions. Juveniles are mottled brown and take about 4–5 years to acquire the distinctive white head and tail.

Social Behavior
Pairs are typically monogamous and may mate for life, reusing and enlarging huge stick nests year after year. Nests are placed in tall trees or on cliffs with a commanding view of water. Clutches usually contain 1–3 eggs, and both parents share incubation and chick-rearing.
Migratory Pattern
Partial migrant
Song Description
The voice is a series of thin, high-pitched chirps and whistles rather than a loud scream. Calls often include repeated, piping notes used in pair communication and territorial contexts.
