Fig. 3From: First description of migratory behavior of humpback whales from an Antarctic feeding ground to a tropical calving groundA Plot of departure date (in Julian day) from the Western Antarctic Peninsula of humpback whales (Megaptera novaeangliae) tagged off the Western Antarctic Peninsula. Departure date was assessed by plotting the latitude of whales against Julian Day and identifying when whales started moving Northward with no return movements.
