Current desires of conspecific observers affect cache-protection strategies in California scrub-jays and Eurasian jays
Many corvid species accurately remember the locations where they have seen others cache food, allowing them to pilfer these caches efficiently once the cachers have left the scene [1]. To protect their caches, corvids employ a suite of different cache-protection strategies that limit the observers' visual or acoustic access to the cache site [2,3]. In cases where an observer's sensory access ca...
متن کاملCareful cachers and prying pilferers: Eurasian jays (Garrulus glandarius) limit auditory information available to competitors.
Food-storing corvids use many cache-protection and pilfering strategies. We tested whether Eurasian jays (Garrulus glandarius) reduce the transfer of auditory information to a competitor when caching and pilfering. We gave jays a noisy and a quiet substrate to cache in. Compared with when alone, birds cached less in the noisy substrate when with a conspecific that could hear but could not see t...
متن کاملAnnex cache: a cache assist to implement selective caching
Efficient instruction and data caches are extremely important for achieving good performance from modern high performance processors. Conventional cache architectures exploit locality, but do so rather blindly. By forcing all references through a single structure, the cache’s effectiveness on many references is reduced. This paper presents a selective caching scheme for improving cache performa...
متن کاملEurasian jays predict the food preferences of their mates.
The cognitive abilities of animals continue to fascinate both scientists and nonscientists. Although the abilities of the primates, our closest living relatives, generally attract most interest, several different lines of research have demonstrated high levels of intellectual capacity in birds, particularly corvids. The members of this family are known for their large brains and have performed ...
متن کاملCache protection strategies by western scrub-jays, Aphelocoma californica: implications for social cognition
Food-caching western scrub-jays cache items themselves, and use observational spatial memory to steal the caches of others. Our aim in this study was to investigate the strategies used by scrub-jays to reduce cache theft by conspecifics. In three experiments, scrub-jays were allowed to cache wax worms in two different locations. In experiment 1, the birds preferred to hide items in distant site...
