Subspecies
No subspecies.
Recent studies of mitochondrial DNA indicate that this species and Golden-winged Warbler (Vermivora chrysoptera) form a clade, separate from the other species currently placed in genus. A recent study indicates that Prothonotary Warbler (Protonotaria citrea) and Swainson's Warbler (Limnothlypis swainsonii) may also be genetically close to this species pair. Hybridizes regularly with Golden-winged Warbler (Vermivora chrysoptera) where breeding ranges overlap. Has hybridized also with Kentucky Warbler (Geothlypis formosa) (hybrid originally described as a new species, Helminthophaga cincinnatiensis. One of the two specimens of this pairing originally thought to have involved Mourning Warbler (Geothlypis philadelphia)), and possibly with Nashville Warbler (Leiothlypis ruficapilla).
