Preble's meadow jumping mouse (Zapus hudsonius preblei)
Where Listed: WHEREVER FOUND
The Preble's meadow jumping mouse (Preble's or PMJM) is a small mammal approximately 9 inches in length with large hind feet adapted for jumping, a long bicolored tail (which accounts for 60% of its length), and a distinct dark stripe down the middle of its back which is bordered on either side by gray to orange-brown fur. To evade predators, the mouse can jump up to three feet.

» Life History
Preble’s meadow jumping mouse inhabits well developed riparian habitat with adjacent, relatively undisturbed grassland communities, and a nearby water source. Well developed riparian habitat includes a dense combination of grasses, forbs and shrubs; a taller shrub and tree canopy may be present. PMJM has been found to regularly use uplands at least as far out as 100 meters beyond the 100-year flood plain. The PMJM constructs day nests composed of grasses, forbs, sedges, rushes, and other available plant material. They may be globular in shape or simply raised mats of litter and are most commonly above ground but also can be below ground. Nests are typically found under debris at the base of shrubs and trees or in open grasslands. An individual mouse can have multiple day nests in both riparian and grassland communities and may abandon a nest after approximately a week of use. Hibernation nests occur underground both within and outside of the 100-year floodplain. Hibernacula have been located under willow, chokecherry, snowberry, skunkbrush, sumac, clematis, cottonwoods, Gambel’s oak, thistle, and alyssum. PMJM typically enter hibernation nests between September and October and emerge the following May. The PMJM does not store food, but survives on fat stores accumulated prior to hibernation.
While fecal analyses have provided the best data on PMJM diet to date, they overestimate the components of the diet that are less digestible. These analyses indicate that the diet of the Preble’s jumping mouse shifts seasonally; it consists primarily of insects and fungi after emerging from hibernation in May, shifts to fungi, moss, and pollen during mid-summer (July and August), with insects again added in September. The shift in diet along with shifts in mouse movements suggests that the PMJM may require specific seasonal diets, perhaps related to the physiological constraints imposed by hibernation. It is likely that seeds also compose a significant part of the diet and PMJM have been observed climbing grass stalks to forage on the seed heads.
Movement / Home Range
Dispersal by Preble’s meadow jumping mouse is thought to be limited; the farthest movement by an individual that has been documented was 0.7 miles within a 24-hour period. However, the PMJM is able to move miles along stream corridors over its lifetime.
The Preble's meadow jumping mouse usually has two litters per year, with an average of five young born per litter. Preble’s are long-lived for a small mammal, in comparison with many species of mice and voles that seldom live a full year. Along South Boulder Creek, Boulder County, Colorado, seven individuals originally captured as adults were still alive two years later, having attained at least three years of age.
Habitat loss, alteration, degradation, and fragmentation resulting from urban development, flood control, water development and other human land uses, especially in riparian habitat, have adversely impacted PMJM populations.
