How could you possibly find little Pingu in there? Picture captures penguin nursery in which thousands of huddled chicks wait for their parents to return with dinner Huge group of emperor penguins pictured in South Georgia in Antarctica by photographer Mike Reyfman By Daily Mail Reporter With their parents in the sea catching fish, thousands of junior emperor penguins are left huddled together to await dinner. But when their food-bearing parents return they may be presented with one slight problem - how to find their chick amongst the mass of youngsters. Despite the thousands of youngsters crowded together on this plain in South Georgia, the parents are incredibly able to locate their youngsters by detecting their individual calls. Take your pick: The huge group of emperor penguins pictured huddling together in South Georgia Odd one out: A lone adult is surrounded by chicks, still showing their brown downy feathers The young birds, displaying their brown, downy feathers, crowd together to keep warm while their parents leave en masse to fetch food. Photographer Mike Reyfman travelled to the frozen wilderness for the first time to witness the huge gathering. He said: 'There must be 100,000s of birds in these nurseries but each chick can be spotted by their mum or dad when they return with food simply by the sound of their voice. 'Penguin babies are gathered like this to keep warm from the extreme cold and because they cannot go out to sea yet as their feathers are not ready. Mr Reyfman, 52, from Chicago, added: 'We spent two days following the flock and it was one the most incredible experiences of my life.' He used a Nikon D4 to capture his images.
