Subspecies
No subspecies.
Closely related to the Yellow-throated Warbler (Setophaga dominica) superspecies group, but generally not included within it as it is sympatric with Yellow-throated Warbler (Setophaga dominica) in Bahama Is. May be sister species with Pine Warbler (Setophaga pinus). Birds from Bahamas described as a geographical subspecies, bahamensis, on basis of longer tail and other differences in morphology, and tend also to be darker, more plumbeous grey on upperparts, yellower on forecrown, less heavily marked with black around yellow throat and breast, and greyer on flanks. Further study is required.
