Mark the bird is a male bird that lives on an island that the humans left and are now testing bombs.
- Mark has a kid that plays "who can catch the worm faster" even though his egg hasn't hatched yet.
- He is clumsy, always trapping himself in boxes. He also likes walnuts and his friends make fun of him for it.
- He also is part dog and is the only male bird that can lay eggs.
- He is one of the few birds who care about things.
