Scatter-hoarder

Hoarding or caching in animal behavior is the storage of food in locations hidden from the sight of both conspecifics (animals of the same or closely related species) and members of other species. Most commonly, the function of hoarding or caching is to store food in times of surplus for times when food is less plentiful. However, there is evidence that some amount of caching or hoarding is done in order to ripen the food, called ripening caching. The term hoarding is most typically used for rodents, whereas caching is more commonly used in reference to birds, but the behaviors in both animal groups are quite similar.

Hoarding is done either on a long-term basis – cached on a seasonal cycle, with food to be consumed months down the line – or on a short term basis, in which case the food will be consumed over a period of one or several days.

Some common animals that cache their food are rodents such as hamsters and squirrels, and many different bird species, such as rooks and woodpeckers. The western scrub jay is noted for its particular skill at caching. There are two types of caching behavior: larder-hoarding, where a species creates a few large caches which it often defends, and scatter-hoarding, where a species will create multiple caches, often with each individual food item stored in a unique place. Both types of caching have their advantage.

Caching behavior is typically a way to save excess edible food for later consumption - either soon to be eaten food, such as when a jaguar hangs a partially eaten prey in a tree to be eaten within a few days, or long term where the food is hidden and retrieved many months later. Caching is a common adaptation to seasonal changes in food availability. In regions where winters are harsh, food availability typically becomes low, and caching food during the times of high food availability in the warmer months provides a significant survival advantage. This phenomenon is referenced in the fable The Ant and the Grasshopper.

However, in ripening caching behavior, animals collect and cache food which is immediately inedible but will become "ripe" and edible after a short while. For instance, tayras (a Central American weasel) have been observed to harvest whole green plantains, hide them, and then come back to eat them after they have ripened. Crocodilians such as the alligator are predators with ineffective teeth action - they can bite prey to kill it but can't tear flesh or chew. Small enough prey are swallowed whole while for larger prey, such as a deer, the carcass is cached underwater and left to rot (or "ripen") until it is easy to eat. Leafcutter ants harvest pieces of inedible leaves and then cache them in underground chambers to ripen with a fungus which is the main food for the colony.
