You might have been wondering: what are birds? Birds are a group of warm-blooded vertebrates constituting the class Aves, characterized by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a 4-chambered heart, and a strong yet lightweight skeleton.

Birds live worldwide. Birds range in size from the 5 cm (2 in) bee hummingbird to the 2.75 m (9 ft) ostrich.

There are about 10,000 living bird species, more than half of which are passerine, or "perching" birds. Sometimes known as perching birds or songbirds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching.

Birds have useful wings whose development varies according to species. The only known bird groups without wings are the extinct moa and 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.

Birds are a group of feathered theropod dinosaurs, and constitute the only living dinosaurs.

About 120 to 130 bird species have become extinct due to human activity since the 17th century, and hundreds more before then. Human activity seems to threaten about 1,200 bird species with extinction. However, efforts are underway to protect birds. Recreational birdwatching is certainly an important part of the ecotourism industry.
