Aves are a class of vertebrates that include birds. They have feathers, wings, and a beak, and are adapted for flight. They inhabit a wide range of habitats, from deserts to oceans, and can live for up to 100 years. The current population of Aves is estimated to be around 10,000 species.
Name Origin: The name Aves is derived from the Latin word for "bird". It was first used by Carl Linnaeus in his 18th century work Systema Naturae to refer to a group of feathered, winged, bipedal, egg-laying vertebrates. This group includes all modern birds, as well as extinct species such as Archaeopteryx.
