However, after the ice sheet melts, they migrate back to shallow waters off the coastline. When ice covers their summer habitats, beluga whales migrate to the open sea for the winter. Young belugas accompany the adults, and migration patterns are passed from one generation to the next. The choice of habitats during the summer is influenced by feeding habits, predators, and reproduction.īeluga whales are seasonal migrators, and some travel up to 4,000 miles annually in search of food, mates, and conducive waters. Females and their young can also be found in the open waters of eastern Beaufort Sea, while adult males prefer the waters of the Canadian Arctic Archipelago. In the first few months of summer, the beluga whales can be found in large numbers in the mudflats of Alaska's Cook Island.
