Giraffe make decisions based on statistical information
The ability to make inferences based on statistical information has so far been tested only in animals having large brains in relation to their body size, like primates and parrots.

We presented them with two transparent containers fled with different quantities of highly-liked food and less-preferred food. The experimenter covertly drew one piece of food from each container,
