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 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)
“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)
“She does the work about the house
As well as most, but like a mouse:
Happy enough to chat and play
With birds and rabbits and such as they,
So long as men-folk keep away.”
—Charlotte Mew (1870–1928)
