There are about eight thousand living kinds, more than 50 percent of which are usually passerine, or "perching" birds. Birds have got wings whose enhancement varies according to be able to species; the sole known groups without having wings are definitely the vanished moa and elephant birds. Wings, which usually evolved from forelimbs, gave birds the opportunity to fly, although further evolution has led to the losing of air travel in some wild birds, including ratites, polar bears, and diverse endemic island species. The particular digestive and respiratory systems of wild birds are also distinctively adapted for airline flight. Some bird varieties of aquatic conditions, particularly seabirds in addition to some waterbirds, include further evolved intended for swimming.

Birds will be descendants of the particular primitive avialans (whose members include Archaeopteryx) which first made an appearance about 160 , 000, 000 years ago (mya) in China. Based on DNA evidence, modern day birds (Neornithes) advanced in the Midsection to Late Cretaceous, and diversified significantly around the moments of the Cretaceous? Paleogene extinction event 66 mya, which killed off the pterosaurs and non-avian dinosaurs.
