Excerpts Adapted from the Birds of Saskatchewan:

Unlike most wood-warblers, which are foliage gleaners, Black-and-white Warblers forage on larger branches and tree trunks. This is more in the manner of the Brown Creeper or Red-breasted and White-breasted Nuthatches, species with which this boldly marked warbler can hardly be confused. Black-and-white Warblers breed from southwest Northwest Territories and Newfoundland south to the southeastern US, and winter from the southeastern coast of the US to northern South America.

Black-and-white Warblers prefer to nest in moist deciduous or mixed forests. "In the Qu'Appelle Valley and along the Souris they are readily found in damp ravines with extensive woods on the south side, or north-facing, rather than the drier north, or south-facing, slopes? (Bob Luterbach).

The Black-and-white Warbler is a fairly common summer resident in southern boreal forest and parkland regions. In the grasslands it ranges from rare to locally fairly common, depending on the area. It is a rare possible breeder in the Foster Lakes area in the north, and a fairly common spring and fall transient across southern Saskatchewan (Smith 1996).
