I don't see how it's any different than a dog burying food for later.I don't think this particular behaviour is so common actually - deferring their immediate desire for food when they know something better is worth waiting for (it varied between individuals in a species after all) - but then I don't know how many different species have been tested for this. And this does seem to be related to intelligence, although there might be other explanations which could account for such behaviour in any particular species due to the way they normally obtain their food.
Or a squirrel stashing acorns instead of eating them now.
