Summary
Hawk-dove models predict stable mixes of aggressive and peaceful strategies in populations.
In depth
Hawk-dove: ESS proportion of hawks = V/C when cost C exceeds value V. War of attrition and producer-scrounger games. Frequency dependence is key.
Payoffs are measured as fitness. A strategy is an ESS if it does better than any rare mutant. Mixed strategies can be stable as proportions of individuals or probabilities for each individual.
Key idea: the best choice depends on what others in the population are doing.
Frequently asked questions
What is Game Theory in Behaviour?
Hawk-dove models predict stable mixes of aggressive and peaceful strategies in populations.
Which area of biology covers Game Theory in Behaviour, and how advanced is it?
Game Theory in Behaviour is one of the 53 topics in Animal Behaviour. It is rated Advanced, so it suits learners who want specialist depth. Related topics in this area include Hamilton's Rule, Foraging Behaviour, Social Groups.
Can you give an example of Game Theory in Behaviour?
Dung beetles show alternative mating tactics of fighters and sneakers.
What should I learn before Game Theory in Behaviour?
Work through the Beginner topics in Animal Behaviour first, such as Animal Behaviour, Innate Behaviour, Learned Behaviour, then return to Game Theory in Behaviour. Advanced topics assume the Intermediate vocabulary.

How is Game Theory in Behaviour different from Hamilton's Rule?
Game Theory in Behaviour: Hawk-dove models predict stable mixes of aggressive and peaceful strategies in populations. Hamilton's Rule: Altruism evolves when relatedness times benefit exceeds the cost, rb greater than c. Read both side by side and note what each one explains.
How should I study Game Theory in Behaviour step by step?
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Hamilton's Rule and explain the difference aloud. Finally, take the Animal Behaviour quiz and come back to this page for any question you miss.
