Abstract
Current ecological theories of social organization rely on economic models to predict an individual’s rules for joining or leaving a group (e.g., Pulliam & Caraco 1984). These decision rules presumably are influenced by natural selection, so that variation in ecological circumstances might induce variation in sociality. For non-breeding individuals the propensity to join a group or remain solitary could depend on relative benefits and costs associated with avoiding predation (reviewed by Caraco & Pulliam 1984), meeting foraging requirements, or the interaction of these and any other factors affecting survival probabilities (e.g., Pulliam 1973, Caraco 1979, Barnard 1980).
