Santino the chimp, who is in a Swedish zoo, gathers up stones and even makes missiles out of concrete to hurl at visitors later on.

Western scrub-jays have also been tested to see if they can make plans for the future.

The jays were kept in cages with a ‘breakfast’ area and a ‘no breakfast’ area. Given the first chance to cache food, the jays cached three times more pine nuts in  in the ‘no breakfast’ area than they did in the ‘breakfast’ area.

This seems to show that they understood there might be no food given to them the following morning and so they tried to ensure they’d have something to eat.

Previously scientists had thought only humans were capable of this sort of thinking, but these kinds of observations seem to indicate amazing abilities in many animals too.

Hens can anticipate the future too. Researchers carried out an experiment where hens could either get a smaller food treat more quickly, or wait a little longer to get a bigger treat. The hens decided to wait!
