Bald Eagle Plumage

Juvenile, immature, and adult bald eagles have a rather variable plumage. Juvenile birds (½ year) have the least variable plumage. However, birds from 1 ½ through 4 ½ years of age show some of the more diverse and unpredictable plumages. Birds of the same age can have completely different plumages. At 4 ½ years, all plumages converge into the adult or definitive plumage, which is acquired at the age of 5 ½ years of age. The adult plumage does not change for the rest of the bird’s life, and it is the same in the male and female eagle. ~ Avian Report with chart
