Like trick-or-treaters sorting their Halloween candy haul, fox squirrels apparently organize their stashes of nuts by variety, quality and possibly even preference, according to new UC Berkeley research.
The study, published today in the Royal Society Open Science journal, is the first to show evidence of squirrels arranging their bounty using “chunking,” a cognitive strategy in which humans and other animals organize spatial, linguistic, numeric or other information into smaller more manageable collections, such as subfolders on a computer.
Fox squirrels stockpile at least 3,000 to 10,000 nuts a year and, under certain conditions, separate each cache into quasi “subfolders,” one for each type of nut, researchers said.
