Excerpts Adapted from the Birds of Saskatchewan:

If you want to see a Black-throated Green Warbler, keep your ears open, as they are frequently heard before they are seen. They have one of the most recognizable songs of all the warblers in Saskatchewan. The Black-throated Green Warbler summers in forests from eastern British Columbia to Newfoundland, south in the Appalachians to Alabama; wintering occurs in Central America, the Caribbean and northern South America.

Black-throated Green Warblers are most abundant in mature mixedwood forest, where they can reach abundances of over 40 territories/100 ha (Smith 2008b). They are also fairly common in the Duck Mountain-Porcupine Hills area in old-growth hardwood forest, especially if the forest has an abundance of white birch (Cumming 2004). Spring and fall migrants may be seen in all types of wooded habitats; they seek out planted conifers in cities, towns, and farmsteads.

This species is a fairly common to common summer resident across the southern boreal forest (Smith 1996). Most Black-throated Green Warblers, like Blackburnian Warblers, appear to follow the forest through southern Manitoba on their way to and from the province and are thus uncommon transients in the south (ibid.).
