A young Cooper's hawk makes use of a large roadside puddle as a bath. Cooper's hawk is a typical Accipiter in all respects. [2] This species tends to be active earlier in the morning than sharp-shinned hawks and Eurasian sparrowhawks (Accipiter nisus) and is generally much more likely to be active in the morning than in the afternoon.

The northern goshawk has been split into two species based on significant morphological and genetic differences: Eurasian goshawk, Astur gentilis;
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.

Left to right: Cooper's hawk, sharp-shinned hawk, and the red-tailed hawk (not to scale). In the United States, chickenhawk or chicken hawk is an unofficial designation for three species of North American hawks in the family Accipitridae: Cooper's hawk (also called a quail hawk), the sharp-shinned hawk, and the Buteo species red-tailed hawk.
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. [2] [3] The name is from Latin astur, asturis meaning "hawk". [4] Species now placed in this genus were formerly assigned to the genus Accipiter.

They are well known in falconry use both in Europe and North America. The northern goshawk has been trained for falconry for hundreds of years, taking a variety of birds and mammals. Other popular Accipiter species used in falconry include Cooper's hawk and the sharp-shinned hawk in North America and the European sparrowhawk in Europe and Eurasia.
[3] [45] [46] Rarely, in the southern stretches of its Asian wintering range, the northern goshawk may live alongside the crested goshawk (Lophospiza trivirgata) which is smaller (roughly Cooper's hawk-sized) and has a slight crest as well as a distinct mixture of denser streaks and bars below and no supercilia.
