Excerpts Adapted from the Birds of Saskatchewan:
Always dressed for a special occasion, with a bold black necklace on its yellow breast, the Canada Warbler is a beautiful bird. The breeding range of the Canada Warbler, mainly in Canada, extends across the southern boreal region from northeastern British Columbia through to the Maritime provinces and south in the Appalachians to Georgia. It migrates along the Gulf coast to winter in northwestern South America.
Canada Warbler nesting habitat consists of riparian willow and alder shrubbery in the presence of slopes (Smith 1996). Its increase as a migrant suggests that it has benefited from forest fragmentation on its breeding grounds, which has allowed colonization of the tangled shrubs and understory it prefers.
The Canada Warbler is an uncommon summer resident of the southern boreal forest and a rare resident (at least formerly) in the Lower Qu'Appelle Valley (Smith 1996). It is probably greatly undercounted as a migrant; it is listed as rare at Saskatoon. Loss of primary forest in the wintering range, some of it in the High Andes, is suspected by some to have contributed to diminution of breeding populations in Canada (COSEWIC 2008b).
