Blackpoll Warbler — Setophaga striata
A striped gray warbler with a distinctive black cap and white face patch. The female is less heavily streaked, lacks the black cap, looks greenish gray above and white below. The male can be confused with the Black and White Warbler, but the black cap and white face pattern are distinguishing features. Its song is a thin zizizizizi on one pitch. It is very difficult to hear, making it hard to find by its song. This warbler nests primarily in coniferous forests in Canada. It winters in South America.
