This mouse also has a nice and long tail that is distinct, with a dark top and light underside, as well as a white tip. As indicated by its name, this mouse is a great jumper, and to do so, they have large hindfeet and significantly smaller front feet. This mouse species does hibernate. However, they do not cash food; instead they will put on a layer of fat before going into hibernation.

Habitat: This mouse is commonly found in forests with dense foliage (plant leaves), in regions that remain damp and have some sort of running water. They can be found in both coniferous (needle trees, e,g,. pine tree), and deciduous (leafy trees, e.g., maple tree) forests.

The mating season is in May, and females will remain pregnant for 29 days (gestation period). Females will have a litter of 2-7 young once a year, which are born in late June-early July. Baby jumping mice depending on their mothers for nutrition (altricial) and will not be able to leave the nest until 34 days after birth. 

Diet: These mice, like other mice species, are omnivorous. Its main diet consists of seeds, fungi, plant material and insects.
