The following tables show that the contents of the cheek pouches 

 differ widely from those of the stomachs, many things being eaten 

 that are never stowed away in the pouches. For instance, more than 

 half of the stomach contents consisted of insects, while no insects were 

 found in the cheek pouches, the latter invariably containing nothing but 

 seeds. This is what might be expected, as the food laid up for winter 

 is carried in the cheek pouches.
