Cerulean Warbler
The Cerulean Warbler, Dendroica cerulea, is a small songbird of the New World warbler family.
Adult males have pale (cerulean) blue upperparts and white underparts with a black necklace across the breast; they have black streaks on the back and flanks. Females and immature birds have greyer or greenish upperparts, a pale stripe over the eye, no streaking on the back and no necklace. All birds have wing bars and a thin pointed bill.
Their breeding habitat is mature deciduous forests in eastern North America. The nest is an open cup placed on a horizontal branch high in a hardwood tree.
These birds migrate to forested mountain areas in South America.
They forage actively high in trees, sometimes catching insects in flight. These birds mainly eat insects.
The song of this bird is a buzzed zray zray zray zray zeeee. The call is a slurred chip.
In fragmented forest areas, this bird is vulnerable to nest parasitism by the Brown-headed Cowbird. This bird's numbers are declining.
