North American pika carrying grasses to store as winter food

Food storage

Food storage is a strategy for getting through hard times when resources are low because of seasonal or other factors. Some store food for only a few hours or days, while others may do it on a seasonal timescale. Many carnivores, such as foxes and leopards, are opportunistic hunters so might stash or bury surplus prey and return to eat it a few days later. Jays and squirrels bury enough nuts to get them through the winter.
