Large group size is a key assumption of the producer-scrounger model of social foraging. However, many social foragers do not face this large, transient group situation and instead forage in small, stable groups where repeated interactions and kinship may influence foraging decisions. A multilevel selection perspective and an investigation of the role of food caching are absent from existing producer-scrounger work. Here, the producer-scrounger literature is reviewed to identify how a multilevel selection perspective might aid in interpreting scrounging behavior. The social caching literature is reviewed, and two main types of cache loss against which cachers must protect are identified and linked to scrounging behavior. Resource value and competitive ability, two factors known to influence both scrounging and caching behavior, are experimentally examined to determine how they might vary in small, stable family foraging groups of cooperatively breeding American crows, Corvus brachyrhynchos.
