Do humpback whales sing the same song everywhere?
The unique dynamics of the song changes collectively, which means all the singers within the population sing the same version. The song's rate change may change however, with a complete turnover to a new song varying by area. In Bermuda one study showed a complete turnover in five plus seasons. In Australia, it was two seasons. The songs differ from population to population - the humpback whales of the North Pacific (Hawaii, Mexico, Japan) have a different song than, for example, the humpback whales of the South Pacific (Australia and the Islands of the South Pacific). Is this is a version of different dialects?
