Why do penguins steal rocks?
Adélie penguins are one of the few penguin species to use rocks when building their nest. “They will collect a lot of rocks to elevate the egg because, when snow starts to melt, if the egg is right on the ground it will drown,” deNapoli said. “So they’ll build a nest out of rocks to elevate the egg off the surface.”

How do penguins pick their mate?
Mate selection is up to the female, and it is the females that compete for the males. In some penguin species, a female selects the same male from the preceding season to mate with. When a female selects a different mate it is usually because her mate from the previous season fails to return to the nesting area.
How does penguin mate?
Both sexes have orifaces called cloacas that are used both for reproduction and for waste. The female lies on her stomach while the male climbs onto her back. The female lifts her tail allowing their cloacas to touch and sperm to be transfered. This process does not take long, often lasting about 10 seconds.

What do penguins do with stones?
When a penguin has selected his pebble, he presents it to his intended companion. If she approves, she puts the stone in her nest and the two are well on their way to becoming mommy and daddy birds. Pebbles are so important to the penguins that males often fight over the prettiest selections.
