Editing Harris's hawk (section)

==Taxonomy==
[[Robert Ridgway]] placed Harris's hawk in its own new subgenus ''Urubitinga (Antenor)'' in 1873,<ref name="Ridgway1873">{{cite journal |last1=Ridgway |first1=Robert |author1-link=Robert Ridgway |title=Catalogue of the ornithological collection of the Boston Society of Natural History.

[[Richard Bowdler Sharpe]] also separated Harris's hawk to a [[monotypic]] genus, ''Erythrocnema'', in 1874. In his ''Catalogue of Birds in the British Museum'', Sharpe gives an extensive synonymy, with various authors having earlier placed ''P. u. harrisi'' in three genera and ''P. u. unicinctus'' in eleven.<ref name="Sharpe1874">{{cite book |last1=Sharpe |first1=R.

A third subspecies ''P. u. superior'' sometimes accepted in the past in the northwest of the species' range (Arizona to Baja California) was believed to have longer tails and wings and to be more blackish than ''P. u. harrisi''; however, the sample size of the original study was quite small, with only five males and six females. Later research concluded that there is not as strong a physical difference as was originally assumed.<ref name=Bednarz>{{cite conference |last=Bednarz |first=J.
