The fight for stones....

Some penguins, like Adelies and Gentoos, breed in nests build from little stones

However, the little stones are sometimes hard to find.....

If all are already taken, penguin has to turn to theft.....

Carry away the booty....

Sometimes in a haste, if the penguin police was watching....

But there are also other dangers....

Other birds, like Snow petrels and Skuas, want to get an egg or a chick for snack
So you have to watch out.....

Till after success finally comes.....
