Subspecies
No subspecies.
Appears to be closely related to, and sometimes regarded as an aberrant member of genus Dendroica, from which it differs in having characteristic tail-cocking habit. Perhaps closest to Plumbeous Warbler (Setophaga plumbea), Arrowhead Warbler (Setophaga pharetra) and Elfin Woods Warbler (Setophaga angelae), which it resembles in retaining distinctive immature plumage throughout first year until first complete moult.
