The Cooper's hawk is a member of the goshawk genus, "Accipiter". The apartments are broken up into three buildings, called Accipiter, Falco, and Buteo. As a species in the genus "Accipiter", the goshawk is often considered a "true hawk". This was due to a mistaken connection with the Eurasian sparrowhawk in the genus "Accipiter". Northern goshawks ("Accipiter gentilis") have reportedly killed both young and adult barred owl. The large and widespread genus "Accipiter" includes goshawks, sparrowhawks, the sharp-shinned hawk and others. The other greatest predatory threat is certain to be the northern goshawk ("Accipiter gentilis"). The Cooper's hawks is a medium-sized hawk and largish for an "Accipiter". Its primary hunting methods recall those of a powerful "Accipiter" such as a goshawk. Its long wings are unlike the short wings of the "Accipiter" goshawks. The Cooper's hawk is a typical "Accipiter" in all respects. This sexual dimorphism is sometimes most extreme in specialized bird-eaters, such as the "Accipiter" hawks. The juvenile plumage of the species may cause some confusion, especially with other "Accipiter" juveniles. Research in genetic phylogeny has since indicated that "Circus" is closely related to "Accipiter". As is common in the genus "Accipiter", male black sparrowhawks are smaller than females.
