More of the same: allopatric humpback whale populations share acoustic repertoire
Background Humpback whales ( Megaptera novaeangliae ) are a widespread, vocal baleen whale best known for producing song, a complex, repetitive, geographically distinct acoustic signal sung by males, predominantly in a breeding context. Humpback whales worldwide also produce non-song vocalizations (...
