What are bird's bills made of?
The beak is a mouth tool in animals that is primarily used to ingest food. All birds have a beak, but octopuses have one too. There is even a mammal that has a beak: the platypus.
Birds have very differently shaped beaks because they get to their food in very different ways. In birds that live in the mudflats, the beak is long and thin and slightly curved. They can use it to poke for worms and crabs in the mud. Pelicans have a skin sac on their beak: they use it to catch fish in the sea. Similarly, people do it with a fishing net. Birds of prey have strong and sharp beaks, so they can use them to tear pieces of meat from their prey. Birds that eat mostly grains have short, powerful bills.
Birds don't just use their beak for feeding. Many birds use it to build their nests by picking up twigs, bringing them to the nest and weaving them there with the other twigs. Woodpeckers chop deep holes in trees with their powerful beak. Many birds beak-feed their young by shoving food down their throats. The young animals, on the other hand, usually have strikingly colored beaks, which they open wide. This is an incentive for the parents to bring more and more food. Some species of birds also use their beak as a weapon when they need to defend themselves.
The fact that birds have such different beaks has evolved over many millions of years. This means that every species of bird has the right beak for its way of life. This development is called evolution.
Birds' beaks are made up of bone and horn. Horn is a hard material that our fingernails and horses' hooves are made of, for example. Birds don't have teeth. In humans and many other vertebrates, the teeth grow in the upper and lower jaw, which are made of bones. In birds, the upper and lower jaws have the upper beak and the lower beak.
