Habits of Jumping Mice

In New York State, where the majority of the following notes were made, we have two widely distributed genera, Zapus and Napoezapus. The former has two subspecies, Zapus h. hudsonius (Zimmerman), that covers most of New York, including the open meadows of the heavily forested Adirondack region, while on Long Island and the lower Hudson Valley, a smaller, paler form, Zapus h. americanus (Barton), occurs. Napaeozapus insignis insignis (Miller), a much brighter animal than Zapus, may be further differentiated by the white tail tip, usually present. It is the handsomest of eastern forest mammals.
