Crest (animal)

Definition and stakes

Cassell's Natural History, Vol…

“ Large as are the crests in the old males, they are barely present in the females and young, and they must be regarded partly as of use to the larger animals, and partly as ornamental; for in animal nature, as a rule, the gentlemen are more beautiful than the ladies, the idea of beauty being, of course, very much a matter of taste. They are evidently protections against falls, and they also give origin to muscles. The back crest, when looked at from behind, is almost fan-shaped, the bone being broad, and the great muscles of the neck and back are attached to it. ”

Portrait of W. P. Pycraft W. P. Pycraft,  The Courtship of Animals

“ This animal is remarkable for the development, in the males alone, of a great crest or casque on the head, which is formed by a large inflatable air-sac over the ridge of the nose, and communicating with the nostrils. When fully inflated, it covers the head as far back as the eye. ”
