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:
“Yet this aboundant issue seem’d to me,
But hope of Orphans, and un-fathered fruite,
For sommer and his pleasures waite on thee,
And thou away, the very birds are mute.
Or if they sing, tis with so dull a cheere.
That leaves looke pale, dreading the winter’s neere.”
—William Shakespeare (1564–1616)
“Spring, the sweet spring, is the year’s pleasant king;
Then blooms each thing, then maids dance in a ring,
Cold doth not sting, the pretty birds do sing,
“Cuckoo, jug-jug, pu-we, to-witta-woo!””
—Thomas Nashe (1567–1601)
“He put before them another parable: “The kingdom of heaven is like a mustard seed that someone took and sowed in his field; it is the smallest of all the seeds, but when it has grown it is the greatest of shrubs and becomes a tree, so that the birds of the air come and make nests in its branches.””
—Bible: New Testament, Matthew 13:31,32.
