Which bird starting with p but cannot fly can swim?

The correct answer is penguin. Penguins are birds that cannot fly but are excellent swimmers. They are found in the Southern Hemisphere, mostly in Antarctica and the surrounding islands. They have streamlined bodies, wings modified into flippers, and thick layers of fat that help them stay warm in the cold waters they inhabit. Penguins are known for their distinctive black and white coloration and their social behavior, often forming large colonies for breeding and protection.
