Feathers set birds apart from any other animal on Earth. Plumage has a variety of important biological functions, including social signaling and survival.

Differences in size, color, weight, and over all appearance are examples of dimorphism in birds. Birds that do not exhibit key differences in size, color, and over all appearance are considered monomorphic.

Below are examples of birds that are monomorphic, or near monomorphic.
