FREEZING temperatures may have skipped over Britain this winter.
But these heart-melting photos show hundreds of penguins huddling together in the face of a biting Antarctic blizzard.
Snow-caked Emperor penguin chicks can be seen huddleing up to their parents for warmth.
The interior of an adult huddle can reach 37 degrees Celsius, according to scientists.
The astonishing photos were taken by photographer Gunter Riehle, who described how the penguin families braved the harsh conditions.
He said: ”When the snowstorms hit with up to 50 knots, the penguin colonies came closer together to give shelter for the birds in the middle.
“One parent is usually nearby and the other parent is fishing so forming ‘kindergartens’ which are watched by a few adults is a common sight.”
But Riehle also described the harsh reality of some penguins succumbing to the freezing temperatures, claiming to have seen dead chicks during his Antarctic expedition.
He added: ”Our camp was 2.6km away from the big emperor penguin colony. I did the trip three times a day most of the days and you passed by many lost eggs and dead chicks.
“In contrast to other penguin species the emperors are much more shy. Nevertheless you can have very close encounters.”
