Ask anything.

are birds mammals

No, birds are not mammals; birds are their own separate animal group.

Birds and mammals are different animal groups. Mammal mothers feed their babies with milk, but bird mothers cannot do that. A bird's body is covered in feathers. A mammal's body is usually covered in fur. Birds hatch from eggs, but most mammals are born alive.

Cats, dogs, horses and people are mammals. Sparrows, eagles, penguins and ostriches are birds. Both groups are warm-blooded, but their bodies are very different.

The most special thing about birds is their feathers. No other animal has feathers like a bird. So if you see an animal with feathers, it is a bird.

What are feathers for

Feathers keep birds warm and help them fly. Every bird has feathers in a different colour and shape. Feathers fall out over time and new ones grow in.

🥚

Hatching from an egg

Birds hatch from eggs, and the mother bird keeps the egg warm. The chick grows inside the egg, then cracks the shell and comes out. Some baby birds can walk as soon as they hatch.

🐄

How mammals get food

Baby mammals feed on their mother's milk. That is why female mammals have milk glands. Cats, dogs and people feed this way.
