Hundreds of dead little blue penguins, also known as kororā, are washing up on beaches around the Far North as the numbers of the cold-water birds plummet, RNZ reports. Department of Conservation’s Graeme Taylor said this huge number of deaths is caused by rising sea temperatures. During La Niña years, the penguins struggle to find food and end up starving and becoming hypothermic. DOC is also warning the kororā aren’t the only birds feeling the impacts of climate change.
