realized that it was highly distinct from ''P. ocellatus.'' As a result of this apparent distinction, the Solomons frogmouth was moved to a newly-coined genus, ''Rigidipenna'' in 2007. The Solomons frogmouth differs from other frogmouths in several ways. For instance, this species has only eight tail feathers instead of the more usual ten or twelve seen in other frogmouths, and the feathers are generally more coarse in texture. It also has barred
