The "Black-and-white Warbler" distinguishes himself by the way he clambers up and down tree trunks and large limbs much like the creeper and nuthatch, hence it was also known as the "Black and White Creeper". However, unlike the Brown Creeper, which only moves up, the black and white goes in either direction.
The female Black & White has a white throat vs. the male's, which is black.
Pairs of Black and White Warblers arrive in early to mid spring, in temperate zones, as far north as British Columbia and Newfoundland, and southward throughout the central and eastern United States.
Calls or song.
This bird utters a monotonous, squeaky "weesee, weesee, weesee, weesee, weesee, weesee, weesee".
Population and distribution.
Family groups can be seen foraging through swampy areas, gardens and parks in late summer, at which time, some move on over their migration routes, which take them across the Gulf of Mexico. Others remain until October, wintering along the Gulf Coast States.
The "Black and White Warbler" builds its nest against the stump of a tree or bush. It is made of bark, rootlets and grass, to hold a cup of 4-5 white eggs, spotted with purple. The fledglings leave the nest early on and fly up into the trees, where their parents feed them.
