Cute Birds Video Information:

Birds¬†are a group of¬†warm-blooded¬†vertebratesconstituting the¬†class¬†Aves¬†/ňąe…™viňźz/, characterised by¬†feathers, toothless beaked jaws, the¬†laying¬†of¬†hard-shelled¬†eggs, a high¬†metabolic¬†rate, a four-chambered¬†heart, and a strong yet lightweight¬†skeleton. Birds live worldwide and range in size from the 5.5¬†cm (2.2¬†in)¬†bee hummingbird¬†to the 2.8¬†m (9¬†ft 2¬†in)¬†ostrich. There are about ten thousand living species, more than half of which are¬†passerine, or “perching” birds. Birds have¬†wings¬†whose development varies according to species; the only known groups without wings are the extinct¬†moaand¬†elephant birds. Wings, which evolved from¬†forelimbs, gave birds the ability to fly, although further evolution has led to the¬†loss of flight in some birds, including¬†ratites,¬†penguins, and diverse¬†endemic¬†island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly¬†seabirds¬†and some¬†waterbirds, have further evolved for swimming.
