In order to stay warm, a penguin must constantly work to keep their feathers clean, well-oiled, and waterproof. This behavior is called preening, and can be done while swimming or on land. Penguins have an oil gland at the base of their tail, and nip at it to transfer the oil to their beak, so they can apply it to the rest of their body.
