European honey buzzard
The similarity in plumage between juvenile crested honey buzzards and the "Nisaetus" hawk-eagles may have arisen as a partial protection against predation by larger raptors. The eagles have stronger bills and talons, and are likely to be less vulnerable than the "Pernis" species. Similar mimicry is shown by the juveniles of the European honey buzzard, which resembles the common buzzard. Although the northern goshawk is capable of killing both species, it is likely to be more cautious about attacking the better protected "Buteo" species.
