Blue Jays are generally considered non-migratory, although some individuals may move south in winter, especially in northern parts of their range.

Vocalizations:

Blue Jays are renowned for their loud and raucous calls, which often carry across the forest.

They also produce a variety of other vocalizations, including whistles, clicks, and chatters.
