Bald eagles don’t actually have bare heads. Their name is derived from the old English word “Balde.” — National Geographic
Adult birds are unmistakable with white head and tail, dark brown body. This MAJESTIC bird is a monument to the "flight of freedom" that is symbolic of our UNITED States. This bird's LIFE must be protected.
Immature birds take four years to reach adult plumage; youngest juveniles have dark brown heads and bodies, some whitish mottling in wings and tail; older immatures may have much more white on body.

bald eagles can be seen on the coasts, rivers, large lakes; in migration, also mountains, open country.
Typically, they stay close to water, also locally in open dry country in a variety of waterside settings, because that’s where prey is abundant, including swamps in Florida, edges of conifer forest in southeastern Alaska, treeless islands in Aleutians, desert rivers in Arizona. They often winter in some very dry western valleys. ///
