Birds

Here Kids, today we r going to talk about birds, different types, how they fly, run and swim.

What is a bird?
Birds are warm-blooded vertebrate animals that have wings, feathers, a beak, no teeth a skeleton in which many bones are fused together or are absent, and an extremely efficient,, one-way breathing system. Flying birds have strong, hollow bones and powerful flight muscles.

Most birds can fly. Birds have a very strong heart and an efficient way of breathing - these are necessary for birds to fly. Birds also use a lot of energy while flying and need to eat a lot of food to power their flight.

Flying birds' wings are shaped to provide lift, allowing them to fly. These light-weight animals have adapted to their environment by flying, which makes them efficient hunters, lets them escape from hungry predators (like cats), and takes them away from harsh weather (migration).

Not all flying animals are birds; and not all birds can fly. The ability to fly has developed independently many times throughout the history of the Earth.
