In the following Hawk-Dove model of fighting vs. displaying, the total payoff is V-C-D, where:

V: value of the resource (= +200)

C: cost of injury, always incurred when losing a fight (but not winning a fight) (= -50)

D: cost of display, always incurred when displaying (= -10)

a. Assuming that Hawks always fight each other, and never display, what would the payoff be for a hawk meting a hawk?

b. Assuming that when Doves meet each other they both display and half of the time one of them wins, what would the payoff be for a Dove meeting another Dove?

c. Assuming that Hawks always attack Doves (who flee without displaying or fighting), what would the payoff be to a Dove meeting a Hawk?

d. What would the payoff to the Hawk (meeting the Dove) be?

e. Would a population of all Doves be an ESS? explain

f. Would a population of all Hawks be an ESS? explain
