‘Megapclicks’: acoustic click trains and buzzes produced during night-time foraging of humpback whales ( Megaptera novaeangliae )
Humpback whales ( Megaptera novaeangliae ) exhibit a variety of foraging behaviours, but neither they nor any baleen whale are known to produce broadband clicks in association with feeding, as do many odontocetes. We recorded underwater behaviour of humpback whales in a northwest Atlantic feeding ar...
