There are about ten thousand living varieties, more than 50 percent of which will be passerine, or "perching" birds. Birds include wings whose growth varies according to species; the sole known groups without wings are definitely the extinct moa and dickhäuter (umgangssprachlich) birds. Wings, which evolved from forelimbs, gave birds the opportunity to fly, although additional evolution has brought to loosing trip in some parrots, including ratites, penguins, and diverse endemic island species. The digestive and respiratory system systems of chickens are also uniquely adapted for airline flight. Some bird species of aquatic conditions, particularly seabirds in addition to some waterbirds, include further evolved regarding swimming.

Many social kinds pass on knowledge throughout generations, which will be considered a sort of tradition. Birds are sociable, communicating with aesthetic signals, calls, in addition to songs, and engaged in such behaviours while cooperative breeding and hunting, flocking, and mobbing of predators. The vast the greater part of bird kinds are socially (but not necessarily sexually) monogamous, usually regarding one breeding time of year at a time, sometimes for years, but rarely for life. Other varieties have breeding devices that are polygynous (one male using many females) or even, rarely, polyandrous (one female numerous males).
