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:
“The sea was wet as wet could be,
The sands were dry as dry.
You could not see a cloud, because
No cloud was in the sky:
No birds were flying overhead—
There were no birds to fly.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
“The air deals blows: surely too hard, too often?
No: it is bent on bringing summer down.
Dead leaves desert in thousands, outwards, upwards,
Numerous as birds; but the birds fly away....”
—Philip Larkin (1922–1986)
“In almost all climes the tortoise and the frog are among the precursors and heralds of this season, and birds fly with song and glancing plumage, and plants spring and bloom, and winds blow, to correct this slight oscillation of the poles and preserve the equilibrium of nature.”
—Henry David Thoreau (1817–1862)
