[edit] Similar SpeciesIn the west, the two most likely confusing species are Townsend’s and Hermit Warblers. Hermit usually has plainer face, greyer 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. [edit] DistributionBreeds from Saskatchewan east to eastern Quebec and Newfoundland; northern Minnesota and Michigan east to Pennsylvania; also along the Appalachians south to northern Alabama. Waynei subspecies found along the Atlantic coastal plain. Winters east Mexico to central Panama. Also winters in the southern tip of Florida. Rare but regular vagrant in the western United States. Accidental vagrant to Greenland (3 records) and Germany (1 19th century record). [edit] TaxonomyConsists of two subspecies. [edit] Subspecies1
