Adult king penguins have yellow-orange comma- or teardrop-shaped markings on each side of the head and on the lower part of the beak, and like all penguins, kings have a black back and white chest.
King penguins are the second largest penguin species, growing to a height of 3-feet tall and weighing between 24-35 pounds. They feed on krill, fish and squid.
Unlike most other penguins, the king does not build a nest; instead, the parent incubates the egg on its feet. The female lays just one egg, cradling it on her feet under a fold of fat. Both parents alternate brooding duty during the egg’s incubation period, which is about 46-54 days. Chicks are almost completely bare at hatching, but they quickly develop a covering of dense gray-brown down. They remain with their parents for around 30-40 days. Later, both depart to search for food, leaving the chick in a communal flock known as a créche.
