Reithrodontomys bakeri

Baker's Small Toothed Harvest Mouse

Order: Rodentia
Family: Cricetidae


Conservation Status: Endangered. This species has a small range and is fragmented into 5 groups

Baker's Harvest Mouse is a medium-sized member of the genus Reithrodontomys. Like other Harvest Mice, it probably eats insects, seeds, and some fruits and leaves, and probably builds its nests out of grasses and other plant matter. Harvest Mice tend not to be territorial, and huddle together in their nests during the day, sometimes even nesting with other small rodents. This communal lifestyle encourages parasites. Harvest Mice usually carry a number of these, including worms, fleas, and mites.

Baker's Harvest Mouse was originally classified as a subspecies of Reithrodontomys microdon, but genetic studies indicate it is unique. It is endemic to Mexico, where it is found in remote pine and oak forests in the mountains of central Guerrero. It occurs in an area where deforestation is a threat, which could make it vulnerable. More work is needed to document its lifestyle, its range, and its conservation status.

The name "bakeri" honors Dr. Robert J. Baker, a professor at Texas Tech University.
