Abstract

Questions: What determines the duration of conventional display in animal contests? Mathematical method: Evolutionarily stable probability distribution of display duration is calculated mathematically. Key assumptions: Display lasts until one of the contestants chooses to fight or flee. The outcome of fighting between two contestants is determined by their relative strength, which is unknown at the beginning but becomes more and more apparent to both contestants with time. Conclusions: The ESS population may include individuals with very different display durations. The more valuable the contested resource and the greater the cost of losing a contest, the longer the display lasts. Animals that assess their opponents with very high or very low efficiency will engage in shorter displays than animals with intermediate assessment efficiency.
