Caching behavior frequently occurs within a social context that may include heterospecific cache pilferers. All else equal, the value of cacheable food should decline as the probability of cache recovering declines. We manipulated gray squirrels’ (Sciurus carolinensis) estimate of the probability of cache recovery using experimental playbacks of the vocalizations of a potential cache robber, the blue jay (Cyanocitta cristata). We used giving‐up densities (GUDs) to quantify relative changes in… 

Quantifying the future value of cacheable food using fox squirrels (sciurus niger)

A conceptual framework for measuring animals’ perceptions of future vs. present food value is developed and tested and it is found that squirrels’ perception of the future value of hazelnuts with their shells intact was found to be 32% higher than their present value.

Evidence of Social Influences on Cache‐Making by Grey Squirrels (Sciurus carolinensis)

This study reports the first evidence that the presence of conspecifics continues to influence the caching behaviour of a scatter-hoarding mammal, the grey squirrel, after a suitable cache site has been selected and the hoarder is filling and covering its cache.

Cache decisions, competition, and cognition in the fox squirrel, Sciurus niger

This dissertation begins with a general overview of the food-storing literature and the natural caching behavior of the scatter-hoarding fox squirrel, and describes a model of the antagonistic relationship between food storing animals and their competitors using agent-based simulations where caching, memory size, and pilfering co-evolve.

Eavesdropping grey squirrels infer safety from bird chatter

It is suggested that eastern gray squirrels eavesdrop on non-alarm auditory cues as indicators of safety and adjust their vigilance level in accordance with the vigilance level of other species that share the same predators.

Fox Squirrels Match Food Assessment and Cache Effort to Value and Scarcity

This is the first study to show that assessment behaviors change in response to factors that indicate daily and seasonal resource abundance, and that these factors may interact in complex ways to affect food storing decisions.

Caching in the presence of competitors: Are Cape ground squirrels (Xerus inauris) sensitive to audience attentiveness?

Cape ground squirrels have the ability to not only monitor the presence or absence of conspecifics but also discriminate individuals on the basis of their attentive state, suggesting this audience sensitivity may have evolved in response to the difference in competitive ability amongst the ranks in how successful individuals are at winning foraging competitions.

Blue jays (Cyanocitta cristata) do not spontaneously eavesdrop on red squirrel (Tamiasciurus hudsonicus) squeals to locate food

Testing whether blue jays eavesdrop on red squirrels by playing back red squirrel squeals, red squirrel rattles, white noise, and chick-a-dee calls in Winnipeg, Manitoba suggested that neitherblue jays nor other passerines eavesdropping on vocalizations emitted in the context of red squirrel disputes over food.

Visual and auditory cues facilitate cache pilferage of Siberian chipmunks (Tamias sibiricus) under indoor conditions.

The results show that females spent less time locating the animal-made caches, but they scatter-hoarded fewer seeds than males in the auditory/visual treatment, which is the first report that visual and/or auditory cues of conspecifics improve cache-pilfering and hoarding in rodents.

Multitasking and eavesdropping in cotton rats foraging under predation risk

Cotton rats eavesdrop on the alarm vocalizations of blue jays and increase their perceived risk of predation during jay alarms, while simultaneously compromising their patch assessment performance, demonstrating the cost of multitasking.



Effects of experience and social context on prospective caching strategies by scrub jays

It is shown that jays with prior experience of pilfering another bird's caches subsequently re-cached food in new cache sites during recovery trials, but only when they had been observed caching.

Audience effects on food caching in grey squirrels (Sciurus carolinensis): evidence for pilferage avoidance strategies

The data provide the first evidence that caching mammals are sensitive to the risk of pilferage posed by an audience of conspecifics, and that they utilise evasive tactics that should help to minimise cache loss.

Steller's Jays Steal Gray Jay Caches: Field and Laboratory Observations

Field observations of Steller's Jays pursuing Gray Jays (Perisoreus canadensis) and attempting to steal their caches are reported, with Gray Jays exhibited evasive behavior and in some cases avoided loss of caches.

The social suppression of caching in western scrub-jays (Aphelocoma californica)

Western scrub-jays appear to adjust their caching behaviour depending on the risk that observers pose to their caches, as caches were only moved around repeatedly on trials where multiple pilfering attempts were made.


The results of this study undertaken in natural condition demonstrated that the presence of another individual was perceived by the Nuthatch as a source of potential cache loss, and in a social context Nuthatches tended to increase internal reserves (fat deposits), also benefiting from the potential robber by sharing vigilance.

Cache protection strategies by western scrub–jays (Aphelocoma californica): hiding food in the shade

Western scrub–jays may selectively cache in the shade as a strategy to reduce the chance of cache theft by observing conspecifics, thereby making the location of cache sites less certain.

Social Caching and Observational Spatial Memory in Pinyon Jays

In the wild, pinyon jays (Gymnorhinus cyanocephalus) live in large, integrated flocks and cache tens of thousands of seeds per year. This study explored social aspects of caching and recovering by

Reciprocal pilferage and the evolution of food-hoarding behavior

It is argued that caching systems based on reciprocal pilfering can be stable and are not necessarily susceptible to "cheaters," animals that pilfer food but do not scatter hoard food themselves, and a model of food hoarding is introduced to support this argument.

Observational learning and the raiding of food caches in ravens, Corvus corax: is it ‘tactical’ deception?

Abstract Group-foraging ravens scatter-hoard when they are competing for food and, to some extent, also raid the caches made by others. We investigated the effects of observational spatial memory on

Food Storability and the Foraging Behavior of Fox Squirrels (Sciurus niger)

Future value of food affects the foraging behavior of squirrels through the balancing of present and future needs, and some properties of caching in the context of a food's future value are explored.
