Subspecies
Buteogallus anthracinus (Sibley and Monroe 1990, 1993) has been split into Common Black-Hawk (Buteogallus anthracinus) and Cuban Black Hawk (Buteogallus gundlachii) following AOU (2007). Mangrove Black Hawk (Buteogallus subtilis) (Sibley and Monroe 1990, 1993; Stotz et al. 1996) is now lumped with Common Black-Hawk (Buteogallus anthracinus) following SACC (2007) and AOU (2008).
Taxonomy controversial. Sometimes considered to include Mangrove Black Hawk (Buteogallus subtilis). Subspecies gundlachii may be valid species. Subspecies gundlachii and especially utilensis sometimes included in nominate. Populations of St Vincent (Lesser Antilles) and south-western USA sometimes awarded separate subspecies, respectively cancrivora and micronyx. Forms superspecies with Mangrove Black Hawk (Buteogallus subtilis).
The following 6 subspecies are recognised:
anthracinus (Deppe, 1830) - South-western and southern USA (southern Utah and Arizona to Texas) through Central America to Panama and northern Colombia, then along Caribbean coast to north-western Guyana, Trinidad and St Vincent (Lesser Antilles); penetrates inland to Huila, Colombia.
utilensis Twomey, 1956 - Cancún I and Cozumel I, off Yucatán; Utila I and Guanaja I, in Gulf of Honduras; and perhaps other adjacent islands.
rhizophorae Monroe, 1963 - Pacific coast of El Salvador and Honduras; probably from extreme south-western Mexico (Chiapas) locally to Nicaragua.
bangsi (Swann, 1922) - Pacific coast of Costa Rica and Panama, including Pearl Is.
subtilis (Thayer & Bangs, 1905) - Pacific coast of Colombia (and offshore islands), Ecuador and adjacent extreme northern Peru (Tumbes).
gundlachii (Cabanis, 1855) - Cuba and Isle of Pines.
