Falcons (/ ˈ f ɒ l k ən, ˈ f ɔː l-, ˈ f æ l-/) are birds of prey in the genus Falco, which includes about 40 species. Some small species of falcons with long, narrow wings are called hobbies , [ 7 ] and some that hover while hunting are called kestrels .
The basal bird Archaeopteryx, from the Jurassic, is well known as one of the first "missing links" to be found in support of evolution in the late 19th century. Though it is not considered a direct ancestor of modern birds, it gives a fair representation of how flight evolved and how the very first bird might have looked.
The order Falconiformes (/ f æ l ˈ k ɒ n ɪ ˌ f ɔːr m iː z /) is represented by the extant family Falconidae (falcons and caracaras) and a handful of enigmatic Paleogene species. . Traditionally, the other bird of prey families Cathartidae (New World vultures and condors), Sagittariidae (secretarybird), Pandionidae (ospreys), Accipitridae (hawks) were classified in Falconifo
