Song activity and structure of the Central American humpback whale breeding stock
Humpback whales, Megaptera novaeangliae, produce very complex songs that are variable over the years. Humpback whales share song components with each other through the process of horizontal transmission if they have come into acoustical contact. Understanding the change in the song over time provide...
