Confirmation of a new breeding ground for humpback whales (Megaptera novaeangliae) in the central South Pacific
Small numbers of humpback whales (Megaptera novaeangliae Borowski, 1781) have been visiting Pitcairn Island in the central South Pacific annually since the early 1990s. The whales have been observed between the months of June and November in mixed groups including adult males, mothers with calves an...
