Taxonomy unstable, with variety of recent treatments: race subtilis (with rhizophorae and bangsi) commonly treated as a separate species, but recent review#R could find no clear-cut phenotypical differences; B. gundlachii usually included in present species, but differs in its overall browner plumage with more, and more conspicuous, pale feather tips (2); much larger white underwing patch (2); presence of ill-defined malar stripe (2); lack of any mottled rufous panel in wing (ns[2]); alarm call consisting of 3–4 notes vs 9–24 in nominate anthracinus#R (allow 2); and smaller size (fide published measurements#R) (at least 1); form utilensis sometimes synonymized with subtilis; populations of St Vincent (Lesser Antilles) and SW USA sometimes awarded separate races, respectively cancrivorus and micronyx. Five subspecies currently recognized.

Subspecies and Distribution
  • B. a. anthracinus (W. Deppe, 1830) – Common Black Hawk – SW & S USA (mainly in Arizona and New Mexico) through Mexico and Atlantic Central America to Panama and N Colombia (penetrating inland to Huila), and E along Caribbean coast to NW Guyana, Trinidad and St Vincent (Lesser Antilles).
  • B. a. utilensis Twomey, 1956 – Cancún I and Cozumel I, off Yucatán; Utila I and Guanaja I, in Gulf of Honduras; and perhaps other adjacent islands.
  • B. a. rhizophorae Monroe, 1963 – Pacific coast from extreme SW Mexico (Chiapas) through El Salvador and Honduras to Nicaragua.
  • B. a. bangsi (Swann, 1922) – Pacific coast of Costa Rica and Panama, including Pearl Is.
  • B. a. subtilis (Thayer & Bangs, 1905) – Mangrove Black Hawk – Pacific coast of Colombia (and offshore islands), SW Ecuador and adjacent extreme N Peru (Tumbes); possibly in extreme NW Ecuador (San Lorenzo area of N Esmeraldas#R).
