Video by @bertiegregory | A king penguin chick wrapped up warm in its unbelievably fluffy coat on St Andrews Bay, South Georgia Island. King penguin chicks take over a year to fledge so they must be capable of surviving the brutal Antarctic winter. Whilst this fluffy brown coat keeps them warm, they possess another key adaptation. During particularly bad years, winter food is so scarce that adults are forced to stay out at sea hunting for months on end. As a result, the chicks possess the ability to go without food for over 5 months! Shot for a new @natgeo online series coming soon. Follow @bertiegregory for more wildlife.
