Grouse generally migrate to escape harsh winter weather conditions; however, some populations of grouse stay in one place all year round. The movements of grouse are dictated by various factors, including food availability, predation pressure, and habitat quality. In general, though, grouse tend to migrate to areas where they will have the best chance of surviving the winter. So if you’re wondering whether or not your local population of grouse is on the move this season, it all depends on the circumstances!
