Humpback Whales, like all baleen whales, migrate between their feeding grounds and their breeding grounds. The seasonal migration brings northern hemisphere baleen whales to the Arctic Ocean for feeding during the summer months and to the equatorial ocean for breeding in the winter.
The same pattern with southern hemisphere whales occur annually. They migrate to the waters surrounding Antarctica for feeding in the summer months and to the equatorial oceans for breeding in the winter.
Their migrations have nothing to do with water temperature. Northrern hemisphere whales and southern hemisphere whales never meet because the seasons are opposite from each other. While the northern baleen whales are breeding in equatorial ocean waters in the winter, their counter parts in the southern oceans are feeding near Antarctica in the summer.
Distinctive markings on a whale flukes allow identification of individual animals. NPS photo.
