Known Predators:
Reithrodontomys montanus is a small mouse with grayish-brown fur. It has a white underside and a dark stripe down the middle of the back. The tail of this species ranges from 20 to 69 mm and is always shorter than the head and body. The tail is also striped and has sparse fur, yet does not appear scaly. Reithrodontomys means "groove toothed mouse" and refers to a groove that is found in the upper incisors. This groove easily distinguishes this genus from others occuring in the same area.
Range mass: 6 to 13 g.
Range length: 54 to 146 mm.
Average length: 116 mm.
Other Physical Features: endothermic ; bilateral symmetry
These mice appear to prefer climax, or nearly climax, well-drained grassland. They are in the highest densities in shorter grasses, but are found in lower numbers in taller grasses. Reithrodontomys montanus builds its nest out of grasses and places the nest slightly above the ground in grasses or shrubs, or on the ground. The species has also been known to take over a bird's nest for its own. In areas with human contact Reithrodontomys montanus has been found in tin cans or other suitable nests.
Range elevation: 80 to 1900 m.
Habitat Regions: terrestrial
Montane harvest mice live in the dry uplands of the Great Plains. They are found in southwestern South Dakota and southeastern Montana south thruough eastern Wyoming, Colorado, and New Mexico, all of Nebraska and Kansa and most of Oklahoma and Texas. Also found in southern Arizona and northern Mexico in the extremes of its range.
Biogeographic Regions: nearctic (Native )
Reithrodontomys montanus often stores food underground for use during severe winters. It eats: seeds, flowers, grasses, cactus fruits, and insects such as grasshoppers.
Animal Foods: insects
Plant Foods: seeds, grains, and nuts; fruit; flowers
Foraging Behavior: stores or caches food
Primary Diet: omnivore
This species was first discovered by Baird in 1855. The discovery was made in a mountainous region of Colorado which led to the species montanus. Later, however, its distribution was found to be the Great Plains, far from any mountains.
Perception Channels: tactile ; chemical
This species is considered common.
IUCN Red List of Threatened Species: least concern
Reithrodontomys montanus is often found in association with many other rodents, however it is usually the least abundant in its communities.
Ecosystem Impact: disperses seeds
Females have 6 mammae. Males have seminal vesicals, preputial glands, ampullary glands, penial spines, and a baculum. Young are born naked and blind. They are well haired at 6 days and their eyes open at 8 to 13 days. Adult size is reached in 5 weeks. Reithrodontomys montanus goes through 2 changes in pelage before reaching adulthood. The juvenile hair is cottony and duller in color. Sub-adult pelage is the same color as adults but the hair is less dense. Males reach sexual maturity at 2 months, while females reach sexual maturity at about 12 weeks
Breeding season: Females give birth year round
Range number of offspring: 1 to 9.
Average number of offspring: 4.
Average gestation period: 21 days.
Average weaning age: 21 days.
Range age at sexual or reproductive maturity (female): 8 to 12 weeks.
Range age at sexual or reproductive maturity (male): 8 to 12 weeks.
Key Reproductive Features: iteroparous ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization ; viviparous
Parental Investment: altricial

The plains harvest mouse (Reithrodontomys montanus) is a species of rodent in the family Cricetidae. It is found in northern Mexico and the central United States.[1]
The dorsal part of the plains harvest mouse is grey with a darker grey mid-dorsal stripe, and the ventral part is whitish.[3] Its tail has less and shorter hair, with the same color as the mid-dorsal stripe.[3] The body length of the plains harvest mouse is 54 to 146 millimetres (2.1 to 5.7 in) total, and the tail is 20 to 69 millimetres (0.79 to 2.72 in) long.[3] The body mass of a female plains harvest mouse is 7.5 to 13.5 grams (0.26 to 0.48 oz), slightly larger than the male at 6.5 to 10.8 grams (0.23 to 0.38 oz).[4] Its hair length differs by season, being 11 mm–12 mm in winter, and 6 mm–7 mm in summer.[4]
R. montanus reaches breeding age at 85 days.[3] The gestation period is about 21 days, and the time between successive gestations is 21 to 27 days.[3] The breeding period for R. montanus living in colder regions (Central United States) is during June to August while in warmer regions (Central America) R. montanus can breed in every month of the year.[3] Lactation period of the female is every month but August to October.[5]
Newborn plains harvest mice weigh about 1 g.[3] It is born naked and blind. Its hair grows in 6 days, it opens its eyes at 8 days, and weaning is in 14 days.[3] Reaching adult size takes 5 weeks. When it is juvenile, the fur is plain, sparse and curled like cotton.[3] As a juvenile, the hair becomes more shiny, but less dense than the adult.[3]
Since the food sources of the plains harvest mouse are mainly invertebrates and seeds,[6] the mouse can be found in grassy fields or grazed prairie.[7] Their nest is globular and has a dimension of 10 to 11 centimetres (3.9 to 4.3 in). It is formed of compacted grasses and has one opening.[3] Sex ratio in their habitat is almost 1:1.[6]
Their main predator is still not identified, but most carnivorous mammals, some reptiles, and amphibians are predators of the mouse.[3]

Reithrodontomys montanus[2][3][4][5][6] är en däggdjursart som först beskrevs av Baird 1855. Reithrodontomys montanus ingår i släktet skördemöss, och familjen hamsterartade gnagare.[7][8] IUCN kategoriserar arten globalt som livskraftig.[1] Inga underarter finns listade i Catalogue of Life.[7]
Arten når en absolut längd (med svans) av 109 till 130 mm och en vikt av 7 till 9 g. Svansen är lika lång eller lite kortare än huvud och bål tillsammans. På ovansidan förekommer gråbrun päls som är mörkare på ryggens topp. Liksom hos andra skördemöss finns rännor i de övre framtänderna.[9]
Arten förekommer i centrala USA och norra Mexiko. Den vistas i låglandet och i bergstrakter upp till 1920 meter över havet. Det typiska habitatet är prärien med kort gräs. Reithrodontomys montanus vistas även i andra gräsmarker och på odlad mark.[1]
Denna skördemus bygger ett näste av gräs som placeras på marken eller i den låga växtligheten. Arten äter frön, örter och insekter. Ofta ligger bara 30 dagar mellan två kullar och per kull föds cirka fyra ungar. Honor blir 8 veckor efter födelsen könsmogna.[1] Dräktigheten varar cirka 21 dagar och ungarna diar sin mor cirka 14 dagar. Individerna blir sällan äldre än ett år.[9]
