The Common Raven breeds from the high Arctic islands (locally) south throughout Canada, except on the central Prairie Provinces and in extreme southern Ontario; it also breeds through the western U.S. The Common Raven is mainly a permanent resident, wintering within the breeding range but wandering sporadically south into the northeastern U.S. Nearly all of the encounter records for ravens (96%) are for birds banded in Nova Scotia, and 88% are for birds encountered in that province. Nearly half the birds had been shot (43%), contributing to the relatively high encounter rate for this species. Movements were relatively short in the eastern populations, as might be expected for a species classified as a permanent resident. Although one bird from Labrador moved more than 500 km (record 1), only 7% of other eastern birds moved more than 200 km (e.g., records 2-4). Over 75% of eastern encounters were within 100 km of the site of banding. By contrast, western ravens appear to be more mobile. The mean distance moved by these birds was 283 km (15 birds), and one (record 5) moved over 1500 km. Four encounters between the Northwest Territories and Alberta suggest that ravens may move south in some winters (record 6) but stay north for others (record 5).
