Closely related to B. ventralis; these two formerly thought to be close also to B. buteo, B. oreophilus and B. brachypterus; has hybridized with B. buteo#R. Race harlani has been treated variously as full species and as colour morph of calurus, but probably better considered a race#R. Likewise, kriderii often considered a morph, mainly within range of calurus, but also in boundary region between calurus and borealis, and generally included within latter; kriderii, however, is a pale form inhabiting an area occupied also by similarly pale race richardsonii of Merlin (Falco columbarius), and is therefore accorded subspecific treatment here. That said, a recent monograph#R notes convincingly that kriderii "does not have a breeding range distinct from those of other subspecies, meaning it cannot, by definition, be a valid subspecies." Fifteen subspecies recognized.
