Certain species of whales in British Columbia undertake some of the largest migrations in the animal kingdom, and the migration patterns vary depending on the species. Humpback whales that feed in BC waters during the summer months migrate in the winter to their warmer breeding and calving habitats in Hawaii and Mexico. Gray whales are known for one of the longest migrations of any mammal. They travel between their feeding grounds in the Arctic, where they feed during the summer, and their breeding grounds in the lagoons of Baja California, Mexico, where they give birth and mate. This migration brings them along the west coast of North America, including the waters of British Columbia.
