Penguins live in cold places like Antarctica. They build nests out of pebbles or carry their eggs on their feet. Both parents take turns watching the eggs, and sometimes only the father watches. When born, Little Blue penguins have gray feathers. Penguins cannot fly but are excellent swimmers, using their wings to propel through water. They porpoise out of the water to breathe and avoid predators. Penguins eat squid and krill and have a layer of fat to keep warm. Gentoo penguins show interest in mating by gifting a pebble to the female.
