The Western harvest mouse can be found in many habitats in North America, including meadows, valleys, marshes, and prairies. They can also live in dunes, deserts, shrublands, and clearings in forests.
The nest can be found under logs, bushes, weeds, and grasses. Nests consist of a construction shaped like a sphere with one entrance.
Their diet consists of flowers, seeds, herbs, and insects such as weevils, moth larvae, and beetles. The Western harvest mouse does not hibernate but does put on body fat to get them through the colder winter conditions where they enter a state of torpor.
The Western harvest mouse is not territorial, and many can live in one nest. This helps them to keep their body temperatures steady in winter.
The Western harvest mouse grows up to 140 mm long with a weight of up to 15g.
