What color is the upper plumage (back and upper wings) of a fully mature White-tailed Eagle?
Answer
Dark brown
The plumage of a fully mature White-tailed Eagle presents a palette of deep, earthy tones. Specifically, the upper surfaces of the bird, which include the back and the upper portion of the wings, are generally a dark brown color. While the undersides tend to appear somewhat paler brown than the upper surface, the most striking feature contrasting with this dark brown is often the head and neck, which exhibit a lighter, sometimes buff or straw-colored shade. The juvenile plumage, in contrast, is much more uniform and dark.
