There are about 10 thousand living species, more than fifty percent of which will be passerine, or "perching" birds. Birds have got wings whose advancement varies according to be able to species; the sole known groups with out wings are the wiped out moa and dickhäuter (umgangssprachlich) birds. Wings, which in turn evolved from forelimbs, gave birds a chance to fly, although additional evolution has guided to the loss of airline flight in some birds, including ratites, penguins, and diverse native to the island island species.

Birds are usually descendants of the primitive avialans (whose members include Archaeopteryx) which first appeared about 160 thousand years ago (mya) in China. Based on DNA evidence, modern birds (Neornithes) advanced in the Middle to Late Cretaceous, and diversified considerably around the time of the Cretaceous? Paleogene extinction event 66 mya, which murdered off the pterosaurs and non-avian dinosaurs.

Many social kinds pass on knowledge around generations, which is definitely considered a form of traditions. Birds are sociable, communicating with visible signals, calls, and songs, and engaged in such behaviours as cooperative breeding and even hunting, flocking, in addition to mobbing of predators. The vast bulk of bird varieties are socially (but not necessarily sexually) monogamous, usually with regard to one breeding season at a period, sometimes for yrs, but rarely intended for life. Other varieties have breeding devices that are polygynous (one male using many females) or, rarely, polyandrous (one female with many males). Birds produce offspring by laying ovum which are fertilised through sexual processing. They are typically laid in the call home and incubated simply by the parents.
