From land and sea, long‐term data reveal persistent humpback whale ( Megaptera novaeangliae) breeding habitat in New Caledonia
Abstract Long‐term monitoring is a prerequisite to understanding and protecting long‐lived species such as cetaceans. In New Caledonia, South Pacific, an endangered sub‐population of humpback whales ( Megaptera novaeangliae ) seasonally congregates for mating and nursing during the austral winter. F...
