Birds are warm-blooded vertebrates and are the only animals with feathers. All birds have wings; however, there are a few species of birds that can't fly. Examples of a bird that cannot fly are the penguin and the ostrich. There are approximately 10,000 species of birds on Earth.
All birds have the same basic needs as humans in order to survive, including water, shelter and food. The most common natural food supply for many bird species include insects, fruits, berries and nectar from flowering plants. Some birds will suck sap out of tree buds.
Feathers can keep birds warm. For birds that fly, wing feathers allow flight and tail feathers are used for steering while flying. The color of a bird’s feathers can be used to help them hide or help them find a mate.
