Subspecies
No subspecies.
Precise relationships unclear. Bay-breasted Warbler (Setophaga castanea) presumed to be closest relative of present species, but little information. Has hybridized with Bay-breasted Warbler (Setophaga castanea). Another hybrid involved Northern Waterthrush (Parkesia noveboracensis) and either Blackpoll Warbler (Setophaga striata) or, more probably, Cape May Warbler (Setophaga tigrina). Birds from Alaska described as a geographical subspecies, lurida, but appear little different from those in rest of species' range.
