Adult Bald Eagles have dark brown feathers on their body and wings, and white feathers on their head and tail. The adult’s beak and feet are yellow.
Juvenile Bald Eagles do not have white heads. In fact, in their first year of life, they are dark brown over their body wings, head, and tail. Their beak and eyes are dark. As they age, juveniles may show white feathers anywhere on the body, especially the breast and under the wings.
At three to four years of age, they begin to develop the white head and tail of the adult. Their beak and eyes lighten in color as they reach adulthood.
A complete white head and tail usually develop between ages four and six.
