Imagine a species in which males can adopt either of two strategies in competitions for territories; an aggressive one (termed Hawk) or a passive one (termed dove). Competition for territories is by combat in hawks and displays in doves. Hawks always beat doves so doves don't even display in response, they merely retreat with no cost. When hawks compete against one another, one wins and one loses with a 50% chance of each result - the winner gains the resources and the loser is injured and pays a cost of 40 units of resource. When doves compete against one another, one wins and one loses with a 50% chance of each result - the winner gains the resources and the loser is exhausted and pays a cost of 5 units of resource.
