Excerpts Adapted from the Birds of Saskatchewan:
The Blackpoll Warbler is one of the miracles of migration. Breeding throughout the taiga from Alaska to the Ungava Peninsula south to mountainous areas of New York and New England, in fall, when they reach the Atlantic seaboard, they undergo hyperphagia, increasing their weight from 11 g to as much as 20 g and even to an extreme 25.6 g (Baird 1999). They then fly southward over the Atlantic to winter in northern South America, a flight of up to 3000 km that takes about 80 hours-no water, no food, no rest.
In its breeding range in subarctic and northern boreal regions, the Blackpoll is at home in spruce bogs and regenerating burns (Smith 1996). As a migrant, it is found in all types of wooded habitat.
In the subarctic and northern boreal forest the Blackpoll is a summer resident but considered uncommon (Nero 1963a, 1967a); there are only a few records from the southern boreal (Smith 1996). It is a common transient throughout the province (ibid.). It may appear to be less common in fall than in spring migration, a difference possibly attributable to the difficulties of identification in fall plumage.
