Well they only have one mate for life. They sing to find their life long mate and once they have found them they stick with them forever.. to be asked to be someones penguin, (if you really like the person of course) is an honor... its one of the sweetest cutest things ive ever heard.....
Keep in mind, I know this isn't for every species of penguin so don't get too hung up on when I say "penguin"
