Least Shrews have a repertoire of tiny calls, audible to human ears up to a distance of only 20 inches or so. Nests are of leaves or grasses in some hidden place, such as on the ground under a cabbage palm leaf or in brush. Weighing in at only a few grams, this shrew is remarkably adaptable, as its extensive north to south distribution attests. From southern New England to northern Panama, the Least Shrew inhabits grassy fields, marshes, and woodland habitats.
