description Bald Eagle Overview
Adult bald eagles are recognizable by their white heads and tails against dark brown bodies. Native to North America, this large bird of prey belongs to the sea eagle group and serves as the national bird of the United States. The familiar adult coloring develops with maturity, so younger birds can look quite different from the image commonly used in national symbols. Fish are a major part of its diet, and suitable habitat includes large inland waters as well as coastal areas.
Bald eagles build substantial tree nests that can grow through repeated use, producing some of the largest nests made by birds. For birdwatchers, the species offers a connection between striking adult plumage and a life closely tied to water. Its nesting behavior also makes it relevant to the study of large raptors and the habitats that support them.
help Bald Eagle FAQ
Why is the bald eagle called bald when its head has feathers?
The name comes from an older use of bald meaning white-headed, not featherless. Adult bald eagles have a white head and tail contrasting with a dark brown body.
At what age does a bald eagle develop its white head?
Juvenile bald eagles are mostly mottled brown and acquire adult-looking white head and tail plumage gradually. The mature pattern generally becomes evident at about four to five years of age.
Where do bald eagles build their nests?
They normally build large stick nests in tall trees or on cliffs near rivers, lakes, and coasts. A breeding pair may reuse and enlarge the same nest over multiple years.
How can you tell a bald eagle from a golden eagle?
An adult bald eagle has a white head and tail, whereas an adult golden eagle remains largely brown with golden feathers on the nape. Young bald eagles can be harder to identify, but their unfeathered lower legs differ from the golden eagle's feathered legs.
