Similar species:

In Spring, the male Tennessee Warbler, with its plain olive upperparts, gray crown, white supercilium and plain white underparts resembles a miniature Red-eyed Vireo but note its thinner, pointed bill and dark eye. In fall, the plumage is more similar to a Philadelphia Vireo but, again, note the thin, sharply pointed bill and smaller size. The Orange-crowned Warbler is very similar but has yellow undertail coverts and blurry streaks on the breast.
