The hawk and the dove 1981

Evolutionary Ecology. The classic Hawk—Dove game is extended to deal with continuous variation in resource-holding potential or RHP, when RHP is observable via any sensory modality but RHP difference is less than perfectly reliable as a predictor of the outcome of an escalated contest. The relationship between sensory and physical magnitudes of RHP is assumed to be governed by Fechner's psychophysical law, whose effect is that contestants interact as if they had perfect information about their relative RHP as opposed to RHP difference. Thus, an animal is aggressive if its RHP exceeds a certain fraction, called its threshold, of its opponent's RHP and otherwise is non-aggressive; and the classic Hawk and Dove strategies correspond to zero and infinite thresholds, respectively. That a lower variance of RHP can imply a lower escalation frequency p is a novel insight of the analysis.
