Aerial behavior of humpback whales Megaptera novaeangliae at the southern limit of the southeast Pacific breeding area
We evaluated the set of aerial displays shown by humpback whales Megaptera novaeangliae in the northern coast of Peru, a region that is considered the southern limit of the breeding area of the stock G in the Southeast Pacific. From August to October 2010, aerial displays were quantified from a whal...
