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:
“It was soldiers went marching over the rocks
And still the birds came, came in watery flocks,
Because it was spring and the birds had to come.
No doubt that soldiers had to be marching
And that drums had to be rolling, rolling, rolling.”
—Wallace Stevens (1879–1955)
“To the birds and trees he talks:
Caesar of his leafy Rome,
There the poet is at home.”
—Ralph Waldo Emerson (1803–1882)
“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)
