Zusammenfassung:We report here on five North Pacific female humpback whales (Megaptera novaeangliae) which demonstrated successful annual reproduction. Two of these females were observed with a different calf in three consecutive summers, and three females were observed with a calf in two consecutive summers. Survival was confirmed through the first migration for 12 calves, with survival documented beyond weaning for two of these whales.
