Northern goshawk Accipiter gentilis, photographed by Elaine R. Wilson.

Belongs within: Accipitridae.
Contains: Circus.

Accipiter is a cosmopolitan genus containing the goshawks and related predators of small birds and mammals. Accipiter species have long shanks, long tails and round, broad wings, and are fast, agile fliers. Molecular data support a close relationship between Accipiter and the harriers of the genus Circus; indeed, the phylogenetic analysis by Jetz et al. (2012) suggests that the latter may even be nested within Accipiter. In this phylogeny, Circus is placed as sister to a clade of relatively large accipiters, including the northern goshawk A. gentilis, the bicoloured hawk A. bicolor and Cooper’s hawk A. cooperii.

A basal clade includes such species as the collared sparrowhawk A. cirrocephalus, Chinese sparrowhawk A. gularis and besra A. virgatus. Members of this clade, found in Asia and Australasia, are dark above (including on the crown) and are often rufous and/or barred on the breast. The grey goshawk A. novaehollandiae is an pale-coloured Australian species, either pale grey above and white below or sometimes even entirely white.
