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.

The birds sang sweet in the mids of the day;
I dreamed fast of mirth and play.

To seem to say good-by;”
