The cerulean warbler (Setophaga cerulea) is a small songbird in the family Parulidae. It is a long-distance migrant, breeding in eastern North American hardwood forests and wintering on the Eastern slope of the Andes in South America during non-breeding season, preferring subtropical forests. It displays strong sexual dichromatism: Adult males have cerulean blue and white upperparts, with a black necklace across the breast and black streaks on the back and flanks. Females and immature birds have bluish-green upperparts, a pale stripe over the eye, no streaking, and are yellow below. All have two white wing bars and a thin, pointed bill. The cerulean warbler is insectivorous and predominantly feeds on insect larvae, though it also comsumes winged insects.
