Differences in the functional use of two migratory stopovers by humpback whales (Megaptera novaeangliae). [PDF]
Humpback whale migration between tropical breeding grounds and polar feeding grounds is an energy-intensive activity undertaken on finite energy stores. The use of stopover sites to rest reduces energetic expenditure and provides enhanced opportunity for
