1st year immature eagles have dark brown eyes.
2nd year immatures have light brown to dark cream eyes.
3rd year immatures have mostly cream-colored eyes
4th year subadults have cream to mostly yellow eyes
5th year adults and all older birds have bright yellow eyes.
Plumage, of course, is another guide to age, the white head and tail indicating an adult. From the solid brown of a first- year bird to adult, feathers are a patchy mix of white and brown, the colors sorting themselves into the most reconized plumage in five years.
