Big surge in whales
HUMPBACK whales are making a comeback, a New Zealand survey shows. The number of humpback whales in the Cook Strait reached a high in 2015, which the New Zealand Department of Conservation says is an encouraging sign for the local population. There were 137 humpback whales counted in the annual survey, including the rare white humpback Migaloo, dwarfing the previous high of 106 in 2012. Survey leader Nadine Bott says the latest survey results provide encouraging signs for the future.
