- Greenish olive crown, nape, and upperparts with indistinct dark centers
- Dark wings and tail
- Two white wing-bars
Female
- Auriculars washed olive
- Whitish throat and sides of chest mottled black
Fall

Similar Species
In the west, the two most likely confusing species are Townsend’s and Hermit Warblers. Hermit usually has plainer face, grayer back and lacks streaking on the sides. Townsend’s has a more contrasting face, often streaking on the back and usually a much more yellow upper breast.
Either a very dull immature Townsend’s or a Hermit X Townsend’s hybrid are likely to cause the most confusion. In these and all cases the wash of yellow across the vent just behind the legs is diagnostic for Black-throated Green.
Distribution
Breeds eastern North America; winters east Mexico to central Panama. Also winters in the southern tip of Florida.
