Penguins' feathers are waterproof for two reasons. 1. To protect against the cold. Their feathers are coated with oil from a gland near the tail to increase the "waterproof" factor. They have a downy underlayer of feathers which traps air against the skin. This layer of air is warmed by the penguin's body heat. 2. To enable them to swim quickly and powerfully by streamlining their bodies. Penguin feathers are short and packed together tightly, overlapping, to keep water away from the skin and to create a smooth surface to lower drag.
