Altruisitc Behavior

                                                    9. Altruistic Behavior

This is a picture of a flock of birds which represents altruistic behavior. Altruistic behavior reduces the fitness of the actor and increases the fitness of  other individuals( recipients). For example, birds will often give off a warning call when they see a predator approaching. This warning call helps all the other birds because they now know that they need to hide, but the individual who gave out the warning call is now at risk of being found.
