Streifenwaldsänger Setophaga striata

Relatively large warbler of the boreal forest. Breeding males have solid black cap and white cheek; compare with Black-and-white Warbler. Breeding females are a washed out, streakier version of male. Immatures in fall are quite different: lemony-yellow head and breast with blurry streaking, white wingbars, and white undertail coverts. Distinctive orange feet help distinguish Blackpoll from similar immature Bay-breasted and Pine Warblers. Breeds in coniferous forest, especially stunted spruces at higher elevations. Found in any forested habitat during migration. Known for its exceptional fall migration over the Atlantic Ocean; can travel from East Coast of U.S. to South America in one nonstop flight!
