Yeşil Sırtlı Ötleğen Setophaga virens

Bright yellow face with olive cheeks, crown, and back. Only breeding males have solid black throat. In all plumages, look for dark streaks on white flanks and yellow wash on vent. Breeds in mixed coniferous forests; migrants can be found in any wooded habitat, usually with tall trees. Winters primarily in Central America and the Caribbean, rarely into northern South America. Compare especially with Townsend’s Warbler on the wintering grounds, but Black-throated Green has a less contrasting face pattern (especially paler crown and cheeks) and less yellow on breast.
