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:
“I sowed the seeds of love,
It was all in the spring,
In April, May, and June, likwise,
When small birds they do sing.”
—Mrs. Fleetwood Habergham (d. 1703)
“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)
“Calico Pie,
The little Birds fly
Down to the calico tree,
Their wings were blue,
And they sang “Tilly-loo!”
Till away they flew—
And they never came back to me!”
—Edward Lear (1812–1888)
