How Fur and Feathers Help

Rabbit and bird illustration. — Fur and feathers help animals survive.

Fur and feathers are special body coverings that help animals survive. These external structures—parts on the outside of an animal's body—solve important problems like staying warm and staying safe.

Fur covers the bodies of mammals like rabbits, bears, and foxes. Fur keeps mammals warm by trapping air close to the skin. This works like a blanket that holds warm air near the body. Fur also provides camouflage, which means it helps animals blend in with their surroundings. A brown rabbit's fur matches the dirt and helps it hide from predators. Some animals, like Arctic foxes, change their fur color with the seasons. White fur in winter helps them hide in snow, while brown fur in summer matches the ground.

Feathers cover birds and serve many purposes. Soft, fluffy feathers close to a bird's body trap air and keep the bird warm, just like fur does for mammals. Feathers also keep birds dry by shedding water. Flight feathers are special feathers with a stiff shape that helps birds fly through the air. Some birds also change their feather colors with the seasons for better camouflage.

Both fur and feathers protect animals from weather and predators while helping them control their body temperature.

Interesting Fact: A single duck has about 14,000 feathers, and most of them are fluffy down feathers that trap air to keep the duck warm in cold water!
