Inside the Humpback Whale Nursery

The fjords of Utría National Park act as a nursery for young humpback whales and provide protection from hungry predators. After a year-long gestation period, these one-ton calves are born in June and July. Mother and calf use the safety of the fjord to practice skills like diving and leaping. Sound waves generated by these leaps are used to communicate with other whales over long distances.
