In the past, men used penguin's feathers to keep warm, and the penguins meat to eat. Several different types of sounds mean different things. One of these sounds would be if there was an enemy like a Killer Whale, or sharks. Another sound would be a mating sound. Penguins would use this sound to get a mate.
Penguins usually live near the ice, or rocks.
This is usually near an ocean, and is easy to get food from. Penguins live in Antarctica, New Zealand, and Australia. For more interesting web sites on penguins visit feel free to visit this webpage.
