Turkey Vulture has a tiny, unfeathered head, holds its wings in a dihedral, and has contrastingly paler flight feathers. Golden Eagle can be quite similar to immature Balds, or to adults at a distance but is all dark as an adult and as an immature has white restricted to the bases of the flight feathers and the bases of the tail feathers. The white is confined to crisp patches on the wing and tail, and is not blotchily scattered about underwings coverts as in immature Bald Eagles. Immature Golden Eagles have yellow ceres while immature Balds have dark ceres.
