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 overarching goal of hawkwatch programs is to provide long-term data on regional raptor abundance to help track population trends through time. [3] Many North American hawkwatchers contribute their count data to the Hawk Migration Association of North America at hawkcount.org, a nonprofit website that coordinates hawkwatching data.
More than 700 pairs of raptors, representing 15 different species, nest on the high canyon walls. Nine additional raptor species use the Snake River area as seasonal hunting grounds during migrations or as wintering areas. Birds of Prey NCA is particularly important for prairie falcons, North America's only endemic falcon. The area is home to a ...
Under traditional classification, the American kestrel is the smallest raptor in America. [11] The American kestrel is sexually dimorphic, although there is some overlap in plumage coloration between the sexes. The bird ranges from 22 to 31 cm (8.7 to 12.2 in) in length [12] with a wingspan of 51–61 cm (20–24 in). The female kestrel is ...
Prior to 1900, the red-shouldered hawk was one of the most common North American raptors. Population densities have decreased precipitously due to the clearing of mature forests (principally the wet hardwood forest they prefer) since that time.
The American goshawk (Astur atricapillus) is a species of raptor in the family Accipitridae. It was first described by Alexander Wilson in 1812. The American goshawk was previously considered conspecific with the Eurasian goshawk but was assigned to a separate species in 2023 based on differences in morphology, vocalizations, and genetic divergence.

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.
Buteo is a genus of medium to fairly large, 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 the New World (Etymology: Buteo is the Latin name of the common buzzard [1]).
