This suggests that raptors tilt their head to rely on the highly acute deep fovea. [42] Like all birds, raptors possess tetrachromacy, however, due to their emphasis on visual acuity, many diurnal birds of prey have little ability to see ultraviolet light as this produces chromatic aberration which decreases the clarity of vision.

Accipitriformes, currently with 262 species and 75 genera in 4 extant families and possibly 1 extinct family, is the largest diurnal raptor order. DNA sequence analyses suggest that divergences within Accipitriformes began around the Eocene/Oligocene boundary about 34 mya, with the split of the group including genera Elanus and Gampsonyx from ...
It occupies the largest breeding range of any diurnal raptor north of the Mexican border, just ahead of the American kestrel (Falco sparverius). While the peregrine falcon ( Falco peregrinus ) has a greater latitudinal distribution as a nester in North America, its range as a breeding species is far more sporadic and sparse than that of red ...
The osprey (/ ˈ ɒ s p r i,-p r eɪ /; [2] Pandion haliaetus), historically known as sea hawk, river hawk, and fish hawk, is a diurnal, fish-eating bird of prey with a cosmopolitan range. It is a large raptor, reaching more than 60 cm (24 in) in length and 180 cm (71 in) across the wings. It is brown on the upperparts and predominantly greyish ...
The Accipitridae family (hereafter accipitrids) is by far the most diverse family of diurnal raptors in the world, with more than 230 currently accepted species. [8] As a member of the booted eagle subfamily, Aquilinae, the martial eagle is one of the roughly 15% of extant species in the family to have feathers covering its legs. [2]
The whistling kite (Haliastur sphenurus) is a medium-sized diurnal raptor found throughout Australia (including coastal islands), New Caledonia and much of New Guinea (excluding the central mountains and the northwest). [2] Also called the whistling eagle or whistling hawk, [3] it is named for its loud whistling call, which it often gives in ...
It is relatively long-winged and long-tailed, having the longest wing and tail relative to its body size of any raptor occurring in North America. [ 10 ] The northern harrier breeds in North America, and its closest relative is the cinereous harrier ( C. cinereus ) of South America.
in Bangladesh. The black kite (Milvus migrans) is a medium-sized bird of prey in the family Accipitridae, which also includes many other diurnal raptors. It is thought to be the world's most abundant species of Accipitridae, although some populations have experienced dramatic declines or fluctuations. [2]
