"Buteo" (Etymology: "Buteo" is the Latin name of the Common Buzzard) is a genus of medium-sized wide-ranging raptors with a robust body and broad wings. In the Old World, members of this genus are called "buzzards", but "hawk" is used in North America. As both terms are ambiguous, buteo is sometimes used instead, e.g., by the Peregrine Fund.

Fossil record [Brodkorb (1962), Mlíkovský (2002)]

A number of fossil species have been discovered, mainly in North America. Some are placed here primarily based on considerations of biogeography, "Buteo" being somewhat hard to distinguish from "Geranoaetus" based on osteology alone:Wetmore (1933)]

*"Buteo fluviaticus" (Brule Middle Oligocene of Wealt County, USA) - possibly same as "B. grangeri"
*"Buteo grangeri" (Brule Middle Oligocene of Washabaugh County, USA)
*"Buteo antecursor" (Brule Late Oligocene)
*?"Buteo" sp. (Brule Late Oligocene of Washington County, USA) [A complete left ulna similar to "Buteo" but of distinctly small size: Cracraft (1969)]
*"Buteo ales" (Agate Fossil Beds Early Miocene of Sioux County, USA) - formerly in "Geranospiza" or "Geranoaetus"
*"Buteo typhoius" (Olcott Early ?- Snake Creek Late Miocene of Sioux County, USA)
*"Buteo pusillus" (Middle Miocene of Grive-Saint-Alban, France)
*"Buteo" sp. (Middle Miocene of Grive-Saint-Alban, France - Early Pleistocene of Bacton, England) [Probably several species; similar to Common Buzzard in appearance and size: Ballmann (1969), Mlíkovský (2002)]
*"Buteo contortus" (Snake Creek Late Miocene of Sioux County, USA) - formerly in "Geranoaetus"
*"Buteo spassovi" (Late Miocene of Chadžidimovo, Bulgaria)
*"Buteo musculosus" (Miocene of Argentina) - formerly in "Thegornis"
*"Buteo conterminus" (Snake Creek Late Miocene/Early Pliocene of Sioux County, USA) - formerly in "Geranoaetus"
*"Buteo" sp. (Late Miocene/Early Pliocene of Lee Creek Mine, USA)
*"Buteo sanya" (Late Pleistocene of Luobidang Cave, China)

An unidentifiable accipitrid that occurred on Ibiza in the Late Pliocene/Early Pleistocene may also have been a "Buteo" [Alcover (1989)] . If this is so, the bird can be expected to aid in untangling the complicated evolutionary history of the Common Buzzard group.

The prehistoric species "Aquila" danana", "Buteogallus fragilis" (Fragile Eagle), and "Spizaetus grinnelli" were at one time also placed in "Buteo".
