Similar species:

The male black-throated green warbler is distinctive with its black
throat, yellow face, and olive crown. Within most of its eastern United
States range, it is unlikely to be confused with any other species. Males
of other western species are somewhat similar: hermit warbler has a
yellow crown, golden-cheeked warbler has a black crown and eyeline,
Townsend's warbler has black cheeks. In fall, the yellow face of the
black-throated green barely contrasts with the greener crown and
cheeks. Blackburnian warbler has a darker crown and cheeks and
white streaks on the back. Townsend's warbler also has darker cheeks.
Hermit warbler has a more uniformly yellow head and less streaking
on the sides.
