(Shufedlt, 1885)

The pinyon mouse (Peromyscus truei) is native to the southwestern United States and Baja California in Mexico. These medium-sized mice are often distinguished by their relatively large ears. The range of this species extends from southern Oregon and Wyoming in the north, and extends south to roughly the U.S.-Mexico border, with a disjunct population known as the Palo Duro mouse (Peromyscus truei comanche) that occupies an area in the vicinity of Palo Duro Canyon in the Texas panhandle.

Description

The fur of pinyon mice varies in color from a pale yellowish brown to a brownish black color, and their feet are a lighter color, varying between dusky and white. They are similar in appearance to the white-footed mouse (P. leucopus), but there are a few distinguishing differences. P. truei tends to have larger ears, as large or larger than the hind foot. They also have a larger tail with a more heavily furred tip. The skull of P. truei is larger than that of P. leucopus, with more inflated auditory bullae and a less robust zygomatic arch than the latter species. [2]

Distribution and habitat

P. truei can be found in a variety of habitats. Although they prefer rocky slopes and pinyon–juniper woodland, they are also found in desert, forest, and grassy plains. They tend to have a larger home range than other Peromyscus, up to 2.9 hectares (7.2 acres) in males, which can possibly be attributed to requiring a large area to search for food in drought conditions. [1] They are flexible in habitat and elevation and are able to adjust to varying climate conditions. [3] In burned out areas they tend to stick to the edges instead of moving into the burn area. [4]

Diet

P. truei mostly feed on fruit, grain, and seeds, but they will also readily eat insects, spiders, and other invertebrates. Adults typically feed on Juniper seeds and berries in the winter, and on acorns in the summer. P. truei are notorious at caching their food supply, and cache networks around their den sites can become quite extensive. In addition, they are capable of surviving on very limited water, which is essential in their mostly arid habitats. [5]

<i>Peromyscus</i> Genus of mammals

Peromyscus is a genus of rodents. They are commonly referred to as deer mice or deermice, not to be confused with the chevrotain or "mouse deer". They are New World mice only distantly related to the common house and laboratory mouse, Mus musculus. From this relative, Peromyscus species are distinguished by relatively larger eyes, and also often two-tone coloring, with darker colors over the dorsum (back), and white abdominal and limb hair-coloring. In reference to the coloring, the word Peromyscus comes from Greek words meaning "booted mouse". They are also accomplished jumpers and runners by comparison to house mice, and their common name of "deer mouse" is in reference to this agility.
