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.

The northern goshawk has been split into two species based on significant morphological and genetic differences: Eurasian goshawk, Astur gentilis; American goshawk, ...
The genus Astur was introduced in 1799 by the French naturalist Bernard Germain de Lacépède. [1] The type species was later designated by the Irish zoologist Nicholas Vigors as Falco palumbarius Linnaeus, 1758, now considered as a junior synonym of Falco gentilis Linnaeus, 1758, the Eurasian goshawk.
Eurasian goshawk, Accipiter gentilis, often referred to simply as the goshawk, since it is the only goshawk found in much of its range (in Europe and Asia). Nearctic. American goshawk, Accipiter atricapillus, often referred to simply as the goshawk, since it is the only goshawk found in much of its range (in North America). Afrotropical
European American settlers first entered the valley in 1851. Other travelers entered earlier, but James D. Savage is credited with discovering the area that became Yosemite National Park. [10] Native Americans had inhabited the region for nearly 4,000 years, although humans may have first visited as long as 8,000 to 10,000 years ago. [11] [12]
An American three-toed woodpecker, which have increased in the park due to pine bark beetles. Woodpeckers are small to medium-sized birds with chisel-like beaks, short legs, stiff tails, and long tongues used for capturing insects. Some species have feet with two toes pointing forward and two backward, while several species have only three toes.

[156] [226] Among Accipiter hawks, the most similar to the red-tailed hawk in diet and size is the American goshawk. In some areas, the prey species of these can be very similar and North American populations of goshawks take many more squirrels and leporids than their Eurasian counterparts do. [129] [227]
