Dipodomys californicus eats mostly seeds and berries. It also consumes some tubers, green vegetation, and may eat a few insects. Individuals of this species make small food caches by burying food in an area near their burrow. Dipodomys californicus seems to prefer manzanita berries in the fall and green vegetation in the spring. They don't need a source a fesh water as they get water from their diet and through metabolic processes. This is widely thought to be an adaptation to life in an arid climate (Kelt, 1988; Nowak, 1995).
Foods eaten include: manzanita seeds and berries, Ceanothus seeds, rabbitbrush, lupines, bur-clover, insects, wild oats, small tubers and green vegetation.
Animal Foods: insects
Plant Foods: leaves; roots and tubers; seeds, grains, and nuts; fruit
Foraging Behavior: stores or caches food
Primary Diet: herbivore (Granivore )
D. californicus may have a slight impact on grain crops. (Eisenberg, 1963)
Negative Impacts: crop pest
Kangaroo rats have no special conservation status.
CITES: no special status
IUCN Red List of Threatened Species: least concern
Dipodomys californicus is not very vocal. Individuals of this species use scent marks and foot drumming to communicate with conspecifics. They mark their territory with scent and if they detect another kangaroo rat nearby, they hit their hind feet on the ground to create vibrations that signal to the other kangaroo rat to go away. No one is exactly sure how much is communicated by footdrumming, but some species of kangaroo rats have very complex footdrumming patterns. (Shier et al., 1999)
Communication Channels: acoustic ; chemical
Other Communication Modes: scent marks ; vibrations
Perception Channels: tactile ; chemical
Dipodomys californicus was originally thought to be a subspecies of Dipodomys heermanni. Biochemical and other data now support the classification of D. californicus as a separate species. (Patton et al., 1976)
This species has no obvious benefit to humans.
Although this species is preyed upon by by several natural predators, it probably does not constitute a significant portion of their diets. Kangaroo rats in general are solitary and do not occur in high concentrations. They do aid in the dispersal of seeds as they don't eat every seed they stash. They are hosts to several species of flea and one species of tick. (Kelt, 1988)
Ecosystem Impact: disperses seeds
Dipodomys californicus is found in California as far south as San Francisco Bay and north to south-central Oregon. This species occurs on the floor of the Sacramento Valley and below 400 m in the foothills of the Sierra Nevada and Cascade mountain ranges. (Grinnell, 1922)
Biogeographic Regions: nearctic (Native )
Dipodomys californicus inhabits open grasslands or open areas in mixed chaparral. It prefers areas that get less than 50 cm of precipitation per year, and requires well drained soils that are suitable for burrowing. This species requires fine sand or soil for dust bathing. It is found from elevations of 60 to 400 m (Brylski, 2001; Kelt, 1988)
Range elevation: 60 to 400 m.
Habitat Regions: temperate ; terrestrial
Terrestrial Biomes: chaparral
No data were found relating specifically to D. californicus. An individual of D. ordii is known to have lived in captivity for 9 years and 10 months. (Nowak, 1995; Nowak, 1999)
Dipodomys californicus ranges from 260 to 340 mm in total length. The tail is longer than the body at 152 to 217 mm in length. Like all kangaroo rats, these animals have large hind feet and small forefeet. Each of their feet has four toes. They have large eyes and ears and silky fur. They are dark colored on top, ranging from cinnamon to nearly black, and are very light underneath. Their long, well furred tail is tufted with white at the tip. They have external cheekpouches on each side of their face. The dental formula of D. californicus is 1/1 0/0 1/1 3/3. Males and females are similar although males tend to be slightly larger. The head-body length of these animals ranges from 260 to 340 mm. In general, D. californicus increase in size towards northern California and Oregon. The juveniles can be differentiated from the adults only by tooth wear and skull characteristics. The species can be differentiated from similar species such as Dipodomys deserti and Dipodomys merriami by their coloration and size. Dipodomys deserti is larger, D. merriami is smaller, and both species are lighter in color. Dipodomys californicus also has a broader face than either of these two species. (Kelt, 1988)
Range length: 260 to 340 mm.
Other Physical Features: endothermic ; bilateral symmetry
Dipodomys californicus is preyed upon chiefly by stealthy hunters such as foxes and owls, so the large auditory bullae found in this species may be an adaptation to improve hearing and thus ability to detect predators. The very long hind legs and feet are an adaptation to enable kangaroo rats to escape quickly by ricocheting-type locomotion, and are found in all members of the genus. (Eisenberg, 1963)
Known Predators:
The mating system of these animals has not been described in the literature.
There isn't much data available on the specific reproductive behavior of D. californicus. Breeding may occur year-round if the conditions are favorable, but is most likely to occur between February and September, peaking from February to April. A female may produce as many as 3 litters per year. Their estrous cycles may be effected by food availability. There are 2 to 4 altricial young per litter.
Within the genus Dipodomys, gestation lasts 29 to 36 days. Birth weights vary between 3 and 6 g. The time until weaning apparently varies, as Dipodomys nitratoides weans its young between 21 and 24 days, and Dipodomys panamintinus weans its young between 27 and 29 days. However, the young of Dipodomys ordii remain in their natal nest for 4 to 5 weeks, indicating that the time of weaning may be later than in the other species mentioned. Individuals of other species in the genus Dipodomys have been known to reach sexual maturity as early as 2 months of age.
(Grinnell, 1922; Kelt ,1988; Nowak ,1995; Nowak, 1999)
Breeding season: February through September
Range number of offspring: 2 to 4.
Key Reproductive Features: iteroparous ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous
Parental care for the altricial young is solely a female occupation, as these mice are strictly solitary outside of the interaction between mother and offspring. Females nurse the young in a protected burrow until they are ready to disperse. (Nowak, 1999)
Parental Investment: altricial ; female parental care

The California kangaroo rat (Dipodomys californicus) is a species of rodent in the family Heteromyidae.[2] However, populations are declining, having not fully recovered after the drought in California from 2013 to 2015 destroyed their habitat (the grasslands) and changed it into desert.
Size
The California kangaroo rat is, on average, 312 mm long, with its tail vertebrae comprising 195mm of that total length. Based on its length, experts conclude the weight of the species to be around 75 grams, making its size fairly normal amongst other kangaroo rats in California.[3] The species generally tends to be larger in the northern areas of its distribution (near Modoc County), whereas the smaller animals are often found further south, near the SF Bay Area and Marin County.[3]
Coloration
Dipodomys californicus has an almost all-white underside, including its feet, belly, and forelegs; they also have a dash of black near the ankle. The upper surface of the body tends to be a dark cinnamon-tan shade, extending everywhere but the face, which features darker facial markings. During the molting season for the kangaroo rat (around July through November), the active shedding of the previous year's fur will result in a lighter-textured coat growing anew; the colors remain consistent, however, and the animals' colors generally don't fade or change throughout their lives.[3]
The California kangaroo rat is endemic to western North America, found in Northern California and southern Oregon.[4] Its distribution is from the Sierra Nevada foothills to Suisun Bay, and northwards in the California Coast Ranges to the foothills of the Cascade Mountains.[1] However, as of 2020, the California kangaroo rat has been found in north Nevada, 1627–1900 meters in elevation. Not only does this make suggest the most easterly sighting of the species, but it also marks the highest altitude that the species has ever been found.[5] California's Kangaroo Mountain was likely named after the California kangaroo rat.[6]
It is an IUCN listed Least Concern species, due to the rather large home area and vast range of its distribution. The populations also thrive due to the fact that the kangaroo rat is adapted to thrive in hostile climates, where very few humans (in general) have encroached or developed infrastructure. In the cases of populations where the kangaroo rats do live within or near to human settlements, their ecological niche seems to be far less offensive and intrusive towards people than house mice or common rats, making their survival even more likely; kangaroo rats do not scavenge off of trash, human food or waste and do not nest in human habitations. Likewise they do not carry the same pathogens as common mice or rats, further ensuring a steady population.[1]
Dipodomys californicus was formerly included as a subspecies of Dipodomys heermanni, but differs enough in chromosomal and biochemical characteristics to warrant being recognized as a distinct species. One such distinction between Dipodomys californicus and other four toed species of Dipodmys heermanni is their unique tail coloration which features a white tip with black stripes on the top and bottom.[5]
