The Bald Eagle (Haliaeetus leucocephalus) of Alaska’s waterways and the soaring Golden Eagle (Aquila chrysaetos) of the Interior are two of this state’s most magnificent birds of prey. Long valued for their aesthetic beauty, eagles are now recognized for their biological importance as scavengers and predators in the natural environment. These raptors deserve our protection and respect.

General description: The Bald Eagle is so named for its conspicuous white head and tail. The distinctive white adult plumage is not attained until 5 or more years of age. Immature birds lack this easily identifiable characteristic and can be confused with the Golden Eagle. The immature Bald Eagle’s unfeathered tarsi (lower legs) and whitish wing linings on the forward part of the wings, can be helpful distinctions where the two species coexist. The Bald Eagle is Alaska’s largest resident bird of prey (the Steller’s Sea Eagle is larger) with a wing span up to 7 1/2 feet (2.3 m) long and weights of 8 to 14 pounds (3.6-6.4 kg). Like many raptors, females are larger than males.
Life history: Found only in North America, Bald Eagles are more abundant in Alaska than anywhere else in the United States. The Alaska population has been estimated to include 30,000 birds at the time of fledging. Bald Eagles are often found along Alaska’s coast, offshore islands, and Interior lakes and rivers. The highest nesting densities occur on the islands of Southeast Alaska. Most Bald Eagles winter in southern Alaska, but some leave the state during cold months. In the Chilkat Valley, over 3,000 birds may congregate in late fall and early winter to feed on spawned-out salmon.
