Abstract
    Aggressive interactions are a common means of contesting resources for most animals. Considerable variation occurs in whether a specific individual wins a particular aggressive contest. Influences on the behaviour of individuals that might produce this variation include, among many factors, hunger, size, residency and age (Beaugrand et al. 1996; Hsu et al. 2006). Behavioural ecologists have been quite successful in understanding variation in contest outcomes, employing benefit/cost models to predict such things as contest duration and winner (e.g. Riechert 1998). Benefits are immediate or longer-term positive effects on fitness of the individual, such as gaining access to food or mates as a result of the contest. Costs include time and energy spent in the contest as well as the possibility of being injured or the increased chance of being taken by a predator.
