We observed radio-implanted Merriam's kangaroo rats disposing of 10-g bonanzas of rolled oats in 48 trials in the field. The principal determinant of the initial disposition of discovered food was apparently its distance from the day burrow: food found within about 10m was mainly larder hoarded, whereas food encountered farther afield was usually dispersed immediately in shallow caches. Cache sites were newly dug for the purpose and not reused; most caches were nearer the current day burrow than was the food source, but a few were placed far from both the cacher's day burrow and its habitual nocturnal range.
