BUTEO

'''Buteo'''^[1]
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 named as "buzzards", but "hawk" is used in North America. As both terms are very ambiguous, "'buteos'" is sometimes used instead, e.g. by the Peregrine Fund [1].

Fossil record

A number of fossil species have been discovered in North America. Some are placed here mainly based on 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) - see Cracraft (1969)

★ ''Buteo ales'' (Agate Fossil Beds Early Miocene of Sioux County, USA) - formerly in ''Geranospiza'' or ''Geranoaetus''

★ ''Buteo typhoius'' (Olcott Early -? Late Miocene of Sioux County, USA)

★ ''Buteo contortus'' (Snake Creek Late Miocene of Sioux County, USA) - formerly in ''Geranoaetus''

★ ''Buteo conterminus'' (Snake Creek Late Miocene/Early Pliocene of Sioux County, USA) - formerly in ''Geranoaetus''

★ ''Buteo musculosus'' (Miocene of Argentina) - formerly in ''Thegornis''

★ ''Buteo'' sp. (Late Miocene/Early Pliocene of Lee Creek Mine, USA)
An unidentifiable accipitrid that occurred in the Late Pliocene/Early Pleistocene of Ibiza 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'' (Miocene), ''Buteogallus fragilis'' (Fragile Eagle, Late Pleistocene), and ''Spizaetus grinnelli'' (Late Pleistocene) were at one time also placed in ''Buteo'' (Wetmore 1933).
