A male myrtle warbler (Setophaga coronata coronata) in breeding plumage, photographed in the Léon-Provancher Ecological Reserve, Québec, Canada. This form, found in the northeastern United States and eastern Canada, is considered conspecific with the Audubon's warbler, which is found further west. The myrtle warbler can be distinguished from the Audubon's by its white eyestripe, white (not yellow) throat, and contrasting cheek patch.Photograph: Simon Pierre Barrette
