Whales’ behaviour

NUKUALOFA - New research from northern Tonga is showing that tourism is disturbing the natural behaviour of Humpback whales. Humpbacks winter-over in Vava’u to give birth and mate before heading back to summer feeding grounds off Antarctica. Auckland University of Technology’s Mark Oram said Vava’u provides sheltered shallows where mothers and calves can bond and feed without interruption from amorous males looking to mate.
