Fairy penguins, also known as little blue penguins, are the smallest species of penguin, standing about 12 to 13 inches tall. They are native to the southern coastlines of Australia and New Zealand. Their distinctive blue feathers help them blend into the ocean when viewed from above, providing camouflage from predators. These penguins are known for their social behavior, often living in large colonies. They primarily feed on small fish and crustaceans, which they catch while swimming. Fairy penguins are also notable for their unique nesting habits, often burrowing into the ground or using natural crevices for shelter.
