Although there is no information regarding predators specific to Peromyscus crinitus, typical predators for other species of Peromyscus include ermine, long-tailed weasels, coyotes, red foxes, Canada lynx, and a number of other mammalian carnivores. Peromyscus crinitus is also preyed upon by owls such as barn owls, great-horned owls and barred owls, and a number of different snake species. It's coloration helps camouflage it from potential predators and likely helps decrease risk of predation.
Anti-predator Adaptations: cryptic
Vocalizations are an important form of communication in canyon mice, especially in young, which often squeak while being cared for by their mother. When injured, adults make brief squeaking sounds, and when defending the nest, they often make "chit" sounds. When excited, canyon mice thump the ground with their hind feet, and when aggressive, they chatter their teeth.
Communication Channels: acoustic ; chemical
Other Communication Modes: pheromones ; scent marks
Perception Channels: visual ; tactile ; acoustic ; vibrations ; chemical
Peromyscus crinitus is classified as a species of least concern on the IUCN's Red List of Threatened Species. It has a rapid reproductive rate and local population densities can be high. Although there are no known major threats to this species, population densities can be significantly impacted by the presence of other species of Peromyscus or other omnivorous rodents. For example, when Neotoma lepida was removed during a competitive interactions study, P. crinitus populations increased 130% over their original numbers and 87% when Peromyscus eremicus was removed.
US Federal List: no special status

There are no known adverse effects of Peromyscus crinitus on humans.
Peromyscus crinitus has been used to investigate chromosomal function, and its lungs cells are used in biomedical research investigating the effects of antitumor antibiotics on mitosis.
Positive Impacts: research and education
Canyon mice are omnivores that consume both insects and plant material. They are important seed dispersers throughout their geographic range and may help control insect pest populations as well. They are host to a number of different endoparasites, including tapeworms and roundworms, and are also vulnerable to a number of different ectoparasites such as ticks, chiggers, mites, fleas, botflies and warble flies.
Ecosystem Impact: disperses seeds
Commensal/Parasitic Species:
Although canyon mice are omnivorous, primarily forage includes plant products such as seeds, leaves, and fruit. Other important food items include various species of insect. Canyon mice cache food for consumption during winter.
Animal Foods: insects
Plant Foods: leaves; seeds, grains, and nuts; fruit
Foraging Behavior: stores or caches food
Primary Diet: omnivore
Canyon mice are native to North America and can be found from central Oregon to northern Baja California, throughout western Nevada, northern Arizona, most of Utah, and in the inter-montane regions of western Colorado.
Biogeographic Regions: nearctic (Native )
Canyon mice prefer arid habitat types and can be found from deserts below sea level to forested montane areas. They are restricted to rocky habitat, and vegetative cover type has little influence on their distribution. Canyon mice can also be found in desert or dune habitat and forage in areas with shrub-like vegetation, which they use for cover when presented with a potential threat.
Range elevation: -82 to 3048 m.
Average elevation: 1574.7 m.

Terrestrial Biomes: desert or dune ; forest ; mountains
There is no information available regarding the lifespan of Peromyscus crinitus. Close relatives, P. maniculatus bairdii and P. maniculatus gracilis, have been known to live up to 15 years in captivity. Typically, wild mice have a very short lifespan, on the range of 1 to 3 years.
Peromyscus crinitus is a relatively small rodent that ranges from 162 to 191 mm in head-body length, with an average of 175 mm. The tail ranges from 80 to 118 mm long and adult mass ranges from 13 to 23 g, with an average of 17 g. The dorsum is covered in brown, black, golden brown, or gray fur and the venter is typically white. Its tail and ears are sparsely furred and their ears and feet, which are approximately equal in length, are tufted. It has long white vibrissae on the snout and large black eyes. Sexual dimorphism has not been reported in this species.

Range basal metabolic rate: 4.80 to 6.26 cm3.O2/g/hr.
Average basal metabolic rate: 5.53 cm3.O2/g/hr.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: sexes alike
Peromyscus crinitus is polygynous, and like many other species of Peromyscus, it is solitary and is social only during breeding season. After parturition, mated pairs separate and females become extremely territorial, chasing out any conspecifics that wander into their home range. Little else is known of this species' reproductive behavior in the wild.
Mating System: polygynous
Peromyscus crinitus breeds year-round, however, reproductive activity peaks during spring (March through May). Estrus lasts for 6.1 days. When lactating, gestation ranges from 29 to 31 days, and 24 to 25 days otherwise. Litter size ranges from 1 to 5 pups with a mean of 3.4, and average birth weight is 2.2 g per pup. Peromyscus crinitus has about 2 litters per year, but as many as 8 have been recorded. Pups are altricial at birth, having only small amounts of fur and pigmentation. They are completely defenseless after parturition and rely on their mother for nutrition and protection. Weaning begins at 21 to 30 days after birth and continues until young are fully independent around 6 to 8 weeks old. Most pups become sexually mature between 4 and 6 weeks after parturition.

Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous
Peromyscus crinitus females nurse pups until weaning, which occurs between 21 and 30 days after parturition. After weaning, young continue to depend on their mother for an additional 4 to 6 months before becoming fully independent. While nesting, females continually maintain the nest. No information regarding paternal care has been reported for this species.

The canyon mouse (Peromyscus crinitus) is a gray-brown mouse found in many states of the western United States and northern Mexico. Its preferred habitat is arid, rocky desert. Vegetation has little or no effect on the distribution of canyon mice, it is instead associated with rocky substrate than any plant. Canyon mice forage in areas with shrub-like vegetation which can be used for protection against predators. It is the only species in the Peromyscus crinitus species group.
Canyon mice eat seeds, green vegetation, and insects. Small animals and insects make up a larger portion of diet when seeds and vegetation are rare. They breed in the spring and summer. Females can produce multiple litters of between two and five young every year. Males do not mate with more than one female, and the homes ranges of females and males overlap.[2] Canyon mice are nocturnal and are active through the year. They usually nest among or below rocks in burrows.
The earliest fossils of canyon mice are from 100,000-130,000 years before present from the Los Angeles Basin.
