Molt nearly finished, this King Penguin eyes me up. Like all birds, King Penguins molt - and in the Antarctic, the energy requirements are substantial. Adult king penguins annually fast ashore for 1 month for molting. By the end of molt, they have lost 44% of their prefasting body mass. About 18% of new feather synthesis occurs at sea, thus reducing both nutrient requirement and fasting duration.
