Red Squirrels Making Middens
Red squirrels bury food for winter consumption both individually as well as in caches or “middens.” These food supply piles may be in a hollow tree, in an underground den or in a hollow at the base of a tree. Middens consist of intact cones, cut when they are green with their seeds still enclosed, as well as debris (woody bracts, or scales, etc.) from the cones that accumulates from the squirrel’s eating the seeds. If a midden is located underneath a favorite feeding site, not only is the midden large (up to four feet tall), the moist, decomposing pile of scales provides an ideal place for stored cones to be kept fresh and viable, as the moisture keeps them from drying and opening. Other foods, including nuts, hawthorn and sumac fruit, are also stored in this way. (Note entrance hole at base of midden.)
