Natural History of the Brush Mouse (Peromyscus boylii) in Kansas With Description of a New Subspecies

The chief differences observed between the brush mouse and other species of the genus Peromyscus in Kansas can be summarized as follows: the brush mouse is a superior and more cautious climber; seldom jumps from high places when under stress; is capable of finding its way better in partial darkness; has a stronger preference for acorns; and sometimes buries or hides seeds or acorns. These are all behavioral adaptations that seem in harmony with its mode of life.
