Birds are vertebrate with wings and feathers. Their body is covered with light and tough layer of feathers and they have very light skeleton, therefore when they use their powerful muscles to flap their wings they are able to attain flight. Some bird species do not have these strong muscle because of which they remain flightless their whole life. Birds do not have teeth, but horn like beaks or bills which they use to pick their food and swallow it. Birds hatch from eggs, and many species build nest for their eggs and young one to let them grow in safety.
