Little evidence that Eurasian jays (Garrulus glandarius) protect their caches by responding to cues about a conspecific's desire and visual perspective

Datasets and statistical analyses (R scripts) of a study investigating whether Eurasian jays can protect their caches by responding to cues about the visual perspective and current desire of an observing conspecific. Five experiments were conducted. Experiments 1 and 2 tested whether jays can integrate the two types of social cues to most effectively limit the risk of cache loss. Experiments 3 and 4 attempted to replicate the previous finding by Legg & Clayton (2014) that Eurasian jays prefer to cache behind an opaque barrier over a clear barrier when observed by a conspecific than when caching in private. Experiment 5 further investigated the previous finding by Ostojic et al. (2017) that jays preferentially cache a type of food that had been eaten to satiety by a conspecific over a food that had not been eaten by the conspecific.
