Birds
In bird anatomy, the rump is the body immediately above the tail. The color of plumage on the rump is a characteristic widely used by ornithologists to distinguish between related species, and sometimes also between males and females of the same species. Similarly, the silhouette of the tailfan is a characteristic widely used for purposes of identification, particularly in the field.
Some birds have a food reservoir pouch in the esophagus that is known as a croup.

Famous quotes containing the word birds:
“Alas, so all things now do hold their peace:
Heaven and earth disturbed in no thing:
The beasts, the air, the birds their song do cease;
The nightes chare the stars about doth bring.”
—Henry Howard, Earl Of Surrey (1517?–1547)
“Birds which are the same color as the foliage in which they nest are less likely to be disturbed by other birds who want to drop in and chat, and therefore last longer.”
—Robert Benchley (1889–1945)
