Submission + - There is a logic to how squirrels bury their nuts (royalsocietypublishing.org)

sandbagger writes: Using hand-held GPS navigators, researchers tracked squirrels from their starting location to their caching location, then mapped the distribution of nut types and caching locations to detect patterns.

They found that the squirrels who foraged at a single location frequently organized their caches by nut species, returning to, say, the almond area, if that was the type of nut they were gathering, and keeping each category of nut that they buried separate. Meanwhile, the squirrels foraging in multiple locations deliberately avoided caching in areas where they had already buried nuts, rather than organizing nuts by type.
