There is exactly one species of bald eagle in Alaska, but you will see two distinct plumages: the classic white-headed adult and the dark brown juvenile. Focus on these differences and the best spots to see them along the coast and rivers.

What is the only species of bald eagle in Alaska?
The bald eagle (*Haliaeetus leucocephalus*) is the only species in Alaska. There are no subspecies, but you will encounter two main age classes: adult (white head and tail) and juvenile (all brown with mottling). Immature birds take about four to five years to reach full adult plumage.
In Alaska, bald eagles sightings usually improve when you slow down and match your first stop to the most useful ID markers and likely lookalikes. Use thestate wildlife huband theroute guideto narrow your first area, then check access, weather, and distance before you settle in. A short walk with one clear viewing plan often beats covering too much ground, especially when habitat changes fast from open edges to brush, wetlands, timber, shoreline, or neighborhood cover.
How can you tell an adult bald eagle from a juvenile?
Adult bald eagles have a pure white head and tail with a dark brown body and wings. Their bill and eyes are yellow. Juvenile bald eagles are mostly dark brown with variable white mottling on the belly and underwings; their bill is dark. The head and tail gradually turn white over several years.
Where in Alaska are bald eagles most commonly seen?
Bald eagles are most abundant along the southeastern coast, especially around the Inside Passage, Kodiak Island, and the Kenai Peninsula. The Chilkat River near Haines hosts one of the largest winter congregations. In summer, look for them near coastal rivers and lakes. Check ourAlaska wildlife overviewfor more regional tips.

What is the best season for confident bald eagle sightings?
Late summer and early fall offer excellent odds because eagles gather near salmon spawning streams. Winter (November through February) produces dramatic congregations along open water, notably at the Chilkat Bald Eagle Preserve. Spring and summer are good for seeing nesting adults with chicks.
How do bald eagles compare to golden eagles?
Golden eagles are the most common lookalike. Unlike bald eagles, golden eagles have a golden-brown nape, fully feathered legs, and a smaller bill. In flight, golden eagles carry their wings slightly more V-shaped, while bald eagles hold wings flat. Juveniles of both species can be confused, but golden eagles lack white armpit patches.
What are the key field marks for identifying bald eagles?
For adults, the unmistakable white head and tail. For immatures, look for a large, dark bird with a massive yellow bill gradually becoming pale. Check the wing shape: long, broad, and fingered. The white belly mottling on younger birds is a useful clue. See ourbald eagle species pagefor a detailed comparison.

How long do bald eagles live?
In the wild, bald eagles can live 20 to 30 years, but many do not survive their first year. In Alaska, banding studies have recorded individuals over 25 years old. Mortality is highest from starvation, electrocution, and lead poisoning.
