Genetic study found that this species forms a clade with B. solitarius, B. albigula, B. swainsoni and B. galapagoensis#R. Has previously been considered to include B. albigula as a higher-altitude race, or even as a synonym, but no intergradation or hybridization reported, despite possible range overlap, and the two appear not to be sister-species#R. Two subspecies normally recognized.

Subspecies and Distribution
  • B. b. fuliginosus P. L. Sclater, 1858 – SE USA (Florida) and Mexico (from Sinaloa and Tamaulipas) S to Panama; also Cozumel I (off NE Yucatán Peninsula, SE Mexico).
  • B. b. brachyurus Vieillot, 1816 – Colombia S to NW Peru (Tumbes), E to Trinidad#R, the Guianas and Brazil (S to Rio Grande do Sul), and S through E Peru and Bolivia to Paraguay and N Argentina (Tucumán, Chaco, Corrientes, Misiones).
