Fall Migration

The whales have been feasting in the Arctic seas since about June, building layers of thick blubber to fuel their journey south. Days grow shorter and northern waters begin to freeze. The food supply dwindles. Gray whales know what to do: They head for their winter home in Mexico's warm waters, thousands of miles to the south. Last winter’s new baby whales have become juveniles. ready to make their first journey south independent of their mothers.
