The Black-and-white Warbler breeds in northern and eastern North America from southern Canada to Florida. It is a very rare vagrant to western Europe, mainly to Ireland and Great Britain.
The summer male Black-and-white Warbler is boldly streaked in black and white. There are two white wing bars. Female and juvenile plumages are similar, but duller and less streaked.
Black-and-white Warblers nest on the ground, laying 4-5 eggs in a cup nest. They feed on insects and spiders, which are sought like a nuthatch, moving up and down tree trunks and along branches.
