October: Swimming and Feasting in the Arctic
Scientists who fly over the arctic feeding areas may see gray whales from the airplane, as in this photo. The whales feast on the arctic feeding grounds from about June through September or October. They must eat to build thick blubber for their southward migration. They begin their journey south to their winter home in early October when the days grow shorter and northern waters begin to freeze.
