The bald eagle has sometimes been considered the largest true raptor in North America. The only larger species of raptor-like bird is the California condor (Gymnogyps californianus), a New World vulture which today is not generally considered a taxonomic ally of true accipitrids. [18]
Buzzards are medium-large raptors with robust bodies and broad wings, or, alternatively, any bird of the genus Buteo (also commonly known as "hawks" in North America, while "buzzard" is colloquially used for vultures). Harriers are large, slender hawk-like birds with long tails and long thin legs.
The now extinct Haast's eagle (Hieraaetus moorei), which existed alongside early aboriginal people in New Zealand, was by far the largest eagle known and perhaps the largest raptor ever. Adult female Haast's are estimated to have averaged up to 1.4 m (4.6 ft) in length, weighing up to 15 kg (33 lb), with a relatively short 3 m (9.8 ft) wingspan.
It is the largest bird of prey throughout its range, [6] and among the largest extant species of eagles in the world. It usually inhabits tropical lowland rainforests in the upper (emergent) canopy layer. Destruction of its natural habitat has caused it to vanish from many parts of its former range, and it is nearly extirpated from much of ...
The largest prehistoric horse was Equus giganteus of North America. It was estimated to grow to more than 1,250 kg (1.38 short tons) and 2 m (6 ft 7 in) at the shoulders. [ 138 ] The largest anchitherine equid was Hypohippus at 403 to 600 kg (888 to 1,323 lb), comparable to large modern domestic horses .
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 ...
Steller's sea eagle is the largest bird in the genus Haliaeetus and is one of the largest raptors overall. Females vary in weight from 6.2 to 9.5 kg (14 to 21 lb), while males are rather lighter with a weight range of 4.9 to 6.8 kg (11 to 15 lb).
Teratornithidae is an extinct family of very large birds of prey that lived in North and South America from the Late Oligocene to Late Pleistocene. They include some of the largest known flying birds. Its members are known as teratorns.
