Some 150,000 penguins died after a massive iceberg grounded near their colony in Antarctica, forcing them to make a lengthy trek to find food, scientists say in a newly-published study, according to AFP.
The iceberg's grounding meant the penguins had to walk more than 60 kilometers to find food, impeding their breeding attempts, said the researchers from the University of New South Wales' (UNSW) Climate Change Research Centre and New Zealand's West Coast Penguin Trust.
