A survey of the distribution and habitat of the red squirrel (Tamiasciurus hudsonicus) was conducted in northern Iowa, southern Minnesota, and Wisconsin. The results indicate that the present range of the red squirrel in Iowa covers the north central counties of the state, and is considerably smaller than that given in earlier surveys. The Iowa red squirrel lives in immature hardwood forests near rivers and lakes. If mature trees arc present, they are used for nesting and caching food. The preferred foods of the Iowa red squirrel are the black walnut (Juglans nigra) and the butternut (Juglans cinerea). In Wisconsin and southern Minnesota the red squirrel usually inhabits coniferous forests.
