Hoard Distribution and Size
Scatter hoarding is the formation of a large number of small hoards. Many species of squirrel, including the eastern gray squirrel and the fox squirrel, are well known for scatter hoarding. This behavior plays an important part in seed dispersal, as those seeds that are left uneaten will have a chance to germinate, thus enabling plants to spread their populations effectively. Many animals are scatter hoarders, including squirrels, chipmunks, and the wood mouse. Cache spacing is the primary technique that scatter hoarders use to protect food from pilferers. By spreading the food supply around geographically, hoarders discourage competitors who happen upon a cache from conducting area-restricted searching for more of the supply. Despite cache spacing, however, hoarders are still unable to completely eliminate the threat of pilferage. However, having multiple cache sites is costly because it requires a good memory. Scatter-hoarders generally have a large hippocampus.
In larder hoarding, the hoard is large and is found in a single place termed (a larder), which usually also serves as the nest where the animal lives. Hamsters are famous larder hoarders. Indeed, the word "hamster" is derived from the German verb "hamstern" which means "to hoard"; similar verbs are found in various related languages (Dutch hamsteren, and Swedish hamstra). Other languages also draw a clear connection between hamsters and hoarding: Polish chomikować, from chomik – hamster; Hebrew hamster; oger (אוגר) comes from to hoarde; le'egor (לאגור). A disadvantage of larder hoarding is that if a cache is raided, this is far more problematic for the animal than if it were a scatter hoarder. While the hoard is much easier to remember the location of, these larger hoards must also be more staunchly defended.

Famous quotes containing the words hoard, distribution and/or size:
“One of the few things I know about writing is this: spend it all, shoot it, play it, lose it, all, right away, every time. Do not hoard what seems good for a later place in the book, or for another book; give it, give it all, give it now.”
—Annie Dillard (b. 1945)
“In this distribution of functions, the scholar is the delegated intellect. In the right state, he is, Man Thinking. In the degenerate state, when the victim of society, he tends to become a mere thinker, or, still worse, the parrot of other men’s thinking.”
—Ralph Waldo Emerson (1803–1882)
“For truly I tell you, if you have faith the size of a mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move; and nothing will be impossible for you.”
—Bible: New Testament, Matthew 17:20.
