Subspecies
Closest relatives of genus may be Empidonomus and Tyrannopsis. Recent molecular-sequence data indicate present genus is monophyletic and sister-group to clade that includes Empidonomus and Griseotyrannus. There are two main clades within genus, loosely corresponding to "tropical species assemblage" and combination of "W" and "E" species groups of earlier authors, but with some exceptions. Phylogenetic analyses indicate it is sister to Tropical Kingbird (Tyrannus melancholicus), the two nested within an expanded "tropical species assemblage" as sister-group to an unresolved clade consisting of White-throated Kingbird (Tyrannus albogularis), Couch's Kingbird (Tyrannus couchii) and Fork-tailed Flycatcher (Tyrannus savana). Subspecies vorax only weakly differentiated.
The following 2 subspecies are recognised:
dominicensis (Gmelin, 1788) - Breeds south-eastern USA (south-eastern North Carolina, Georgia, and south-eastern Mississippi to Florida), Bahamas and Greater Antilles, and also locally in north-central Venezuela (south to Apure), Trinidad and Tobago, Curaí§ao, Bonaire, and possibly northern Colombia. Winters from Panama south to central Colombia and southern and eastern Venezuela.
