About Birds
Birds are warm-blooded vertebrates that lay eggs. A bird’s skin is covered with feathers, and all living species have wings made from modified forelimbs, even though some species do not fly. The origin of birds goes back to the Jurassic period. Modern birds have no teeth unlike their predecessors. Birds are found on all seven continents and play an important role in the earth’s ecosystem.
