{"fact":"Crows possess a \"theory of mind,\" shown by their ability to anticipate the actions of other crows based on their own experiences, such as re-caching food if they've been observed by a potential thief.","context":"Scrub-jays that had previously stolen another bird’s cache subsequently re-cached food when they had been observed during caching. Birds without the experience of stealing did not recache their food when they were observed during caching. These results indicate that the re-caching in sites unknown to the observer depends on the previous experience of having stolen food caches (Clayton et al., 2003).","source":"Janina A.
