What is plumage?

• A. Feathers covering the body.
• B. The color range of a bird's plumage across seasons.
• C. The structure of a bird's beak.
• D. The sound a bird makes.

Answer: (A)

Plumage is the feathers that cover a bird's body. It includes all the different kinds of feathers—down for warmth, contour feathers that shape the body, and the specialized flight feathers on the wings and tail. Plumage serves many roles: insulation, waterproofing, flight, camouflage, and signaling or attracting mates through color and pattern. It can also change with molt and seasons, and may differ between ages or sexes in some species, helping birds adapt to their environment and communicate. The other options describe features not defined by plumage: seasonal color changes relate to variation in plumage, the beak’s structure is a different feature, and the sounds a bird makes are its vocalizations.
