Black-and-white Warbler Mniotilta varia

Distinctive warbler with bold black-and-white stripes over entire body. Adult males have black throat and cheek; females and immatures have white throat and paler cheek. Creeps along branches like a nuthatch, searching for insects. Breeds in mature deciduous or mixed forests; winters in a wider variety of wooded habitats as far south as northern South America. Listen for high pitched “squeaky-wheel” song. Breeding male Blackpoll Warbler is potentially confusing, but note different behavior and face pattern.
