Crest

A group of elongated feathers on the top of a bird's head, which may be raised during courtship or to indicated alarm. A crest is often a prominent plumage feature, but in some species it is not easily visible when lowered.^[1]

The cockatoo family, including the Cockatiel, have prominent crests.
