Birds

There are very many bird species on earth. They come in many sizes and colours, but all birds are remarkably similar in build. Birds have a beak and are covered in feathers. Birds have two legs only. The frond legs have become wings. And yes, all birds lay eggs. Birds are the only descendants from the dinosaurs still in existence. Being able to fly they have little competition from other animals. The only other larger animals capable of flying are the bats. Of course we do know exotic creatures like flying dogs and flying fish. But these do not fly really, they are merely capable of gluiding through the air. Some birds can not fly, but still have wings. Many running birds, such as oistriches, use their wings balancing when walking. Other birds, such as pinguins, use their wings te swim. Birds are very common in gardens. You may easily identify over 50 species in an ordinary garden.
