Totally nuts: Squirrels bury their food according to type

We might take it for granted, but organizing large diverse sets into smaller subsets makes finding what you’re looking for easier. Now, it turns out that fox squirrels employ a similar method of categorization—known as “chunking”—to sort their nuts. Similar to how a bookstore might have fiction, nonfiction, poetry, etc., a new study in Royal Society Open Science shows that squirrels who foraged in a single location deliberately bury nuts of similar type together, separating all the almonds from the pecans, for example. Squirrels that foraged in multiple locations, however, employed a simpler method of organization, always burying nuts in new areas irrespective of type, Popular Science reports.
