Similar species
The relatively plain face pattern and yellow throat and breast of the Pine Warbler is somewhat similar to the Yellow-throated Vireo but the vireo has spectacles and a thicker bill. In Fall, the plumage is similar to the basic and immature plumages of several other warblers.

The Blackburnian Warbler has white streaks on the back and a broader supercilium. Blackpoll Warbler has yellow legs and feet and a streaked back. Bay-breasted Warbler also has a streaked back, buffy undertail coverts and less streaking on the breast. Cape May Warbler has more streaking across the breast and a pale mark on the side of the neck. Orange-crowned Warbler has yellow undertail coverts and lacks wing bars.
