Adelie penguin and newborn chicks. There are actually two of them there, the one on the right has its head tucked in, the one on the left has its body tucked in. These chicks are only a day or so old.
Dead Adelie Penguin Chick. Only about 20% of the chicks survive, most fall prey to predators such a skuas and leopard seals. The penguin rookeries are littered with the corpses of frozen dead chicks from over the years.
