Rumped

Rumped is an adjective used in zoology and ornithology to describe an animal, particularly a bird, that has a distinct or prominent rump. The rump is the area of the body at the base of the tail. This term is often used in field guides and identification keys to help distinguish between similar species.

The color, pattern, or size of the rump can be a key diagnostic feature. For example, some species of flycatchers are identified by the color of their rump, such as a yellow rump or a blue rump. Similarly, in some bird families, like sparrows or warblers, the rump's coloration can be a crucial factor in differentiating between males and females, or juvenile and adult birds.

Beyond birds, the term "rumped" can also be applied to other animals, though it is less common. For instance, it might be used to describe mammals with a particularly noticeable or colored rump. The descriptive usage of "rumped" serves as a visual cue for observers, aiding in the precise identification and study of animal life.
