On alternate mornings eight jays were given breakfast in one compartment or refused breakfast in another, before being allowed free access to food the rest of the day. On the sixth day of the experiment they were suddenly given whole pine nuts suitable for caching in the evening. The researchers observed that the jays consistently cached most pine nuts in the tray in the ‘no breakfast?compartment, anticipating that they would not be fed in the following morning in that compartment.
Another experiment showed that the birds were able to plan ahead to provide themselves with a more varied diet. The jays were consistently given a breakfast of peanuts in one compartment and dog kibble in the other. When the birds in the evening were offered both foods, they preferred to cache peanuts in the kibble compartment and vice versa ?to make sure they had an interesting breakfast the following morning.
“The jays spontaneously plan for tomorrow, without being motivated by their current needs? said Nicola Clayton, Professor of Comparative Cognition at the University of Cambridge. “People have assumed that animals only have a concept of the present, but these findings show that jays also have some understanding of future events and can plan for fu
