King penguins are the second-largest species of penguin, known for their striking orange and yellow markings on their heads and necks. They typically weigh between 24 to 40 pounds and stand about 3 feet tall. These birds are primarily found on sub-Antarctic islands, where they thrive in cold, harsh environments. King penguins are social animals that live in large colonies, often numbering in the thousands. They are excellent swimmers, using their wings as flippers to navigate through the water in search of fish and squid, which make up their diet. Breeding occurs in the summer months, with a unique incubation process that involves both parents caring for the egg.
