Excerpts Adapted from the Birds of Saskatchewan:
A secretive bird, unless you hear it first, the Mourning Warbler is difficult to find. However, it sometimes sings from a conspicuous perch staying still for long periods. Mourning Warblers nest in a band of the southern boreal forest from southwestern Yukon to Newfoundland, south in the Appalachians to North Carolina; they winter in a limited area from southern Central America to northwestern South America.
Because this forest-dwelling bird prefers second-growth in clearcuts, along cutlines, and around windfalls or burns, its territory is fluid, changing when the undergrowth forms a closed cover. More rarely, it nests in muskegs or fens. On migration it seeks out the densest shrubbery available.
Smith (1996) considered the Mourning Warbler to be a common summer resident in the southern boreal forest, while it is uncommon and local in the parklands, including the Eagle Hills, Touchwood Hills, Qu'Appelle Valley, Moose Mountain, and perhaps Douglas Provincial Park. It is uncommon and local north to Maribelli and Costigan Lakes in the northern boreal forest. As a migrant it occurs uncommonly throughout southern Saskatchewan.
