Little research has been conducted on communication in Tatera indica. However, like most mammals, they communicate through auditory, chemical, visual, and tactile signals. As nocturnal rodents it is likely that they perceive their environment largely through auditory and chemical signals, as well as using their vibrissae to sense tactile stimuli.
Communication Channels: visual ; tactile ; acoustic ; chemical
Perception Channels: visual ; tactile ; acoustic ; chemical
Tatera indica is not listed by CITES or the IUCN, they are the most common species of gerbil in the Indian subcontinent and are abundant throughout their range.
US Federal List: no special status
CITES: no special status
IUCN Red List of Threatened Species: least concern
Tatera indica are crop pests, especially in areas where grain is stored. The animals will feed on seeds, sprouts, mature plants, ears of corn, and saplings in orchards.
The presence of this species in villages results in transfer of fleas from wild to domestic rodents, which may be partly responsible for the transmission of bubonic plague in and around India.
Negative Impacts: injures humans (carries human disease); crop pest
These gerbils consume large quantities of insects which are potential agricultural pests. Indian gerbils are also hunted for food in southern India.
Positive Impacts: food ; controls pest population
The role of Tatera indica in the ecosystem is not well understood. However, it is clear that, through their abundance and food habits, they significantly impact populations of plants and arthropods throughout their range. They also serve as an important prey base for birds of prey and other small to medium-sized predators. Their burrowing activities aid in soil turnover and the re-distribution of soil nutrients.
The diet of Indian gerbils consists of grasses, leaves, roots, and grains. They also eats grubs, insects, and nestling ground birds. T. indica store grain in their burrows for consumption in the dry season and move on to roots and fruits of plants when the stores have been consumed. During the wet season insect availability increases and the proportion of insects and other arthropods in their diet rises to as high as 40%. This species has also been known to kill and eat smaller rodents and other mammals. Cannibalism on young is common in both captivity and the wild.
Animal Foods: birds; mammals; insects; terrestrial non-insect arthropods
Plant Foods: leaves; roots and tubers; seeds, grains, and nuts; fruit
Foraging Behavior: stores or caches food
Primary Diet: omnivore
The range of Tatera indica includes India, Sri Lanka, Pakistan, as far west as Syria, and north to Afghanistan and Nepal.
Biogeographic Regions: palearctic ; oriental
Tatera indica individuals prefer sandy plains and grasslands that allow extensive burrowing. They will dig extensive burrows with chambers for resting, food storage, and sleeping. The depth of a burrow depends on the surrounding soil composition and season. These gerbils are generally not found in areas with very low rainfall or cold temperatures. They occupy almost any kind of habitat if there is enough suitable food and are found frequently near agricultural fields. These are perhaps the most common gerbil species throughout much of their range.
Habitat Regions: temperate ; terrestrial
Terrestrial Biomes: desert or dune ; savanna or grassland
Other Habitat Features: agricultural
A captive Tatera indica lived for 7 years. In the wild, however, most individuals don't survive their first year of life and adults probably live only a few years.

Tatera indica is one of the largest species in the murid subfamily Gerbillinae. Body mass ranges from 100 to 227 grams, and body length from 15 to 17 centimeters. Color ranges from reddish brown to fawn. Thick fur covers the body but the tail hair is sparse. A small tuft of black hair is found at the tip of the tail. The tail is approximately one half the body length of the animal and has a light brown band on each side. The soles of the feet are hairless and pigmented, as in other members of the genus Tatera, while the ears are also naked and elongated.
Range mass: 100 to 227 g.
Range length: 150 to 170 mm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: sexes alike
Average basal metabolic rate: 0.422 W.
These gerbils are primarily preyed on by birds of prey, especially owls. Jackals, snakes, lizards, cats, and foxes will also eat these gerbils. Their primary means of escaping predation are nocturnality, escaping to their burrows, and heightened senses that allow them to detect predators. They are also very fast and can leap meters into the air when surprised.
Known Predators:
Males and females of this species live apart. The relationship between the sexes is currently not known.
It is not yet known whether mating occurs above or below ground in burrows. Duration of the estrous cycle was found to be 4.5 days in the laboratory. The gestation period for T. indica ranges from 21 to 30 days, with litter size ranging from 1 to 10 young, with 5 to 6 being the most common number of young per litter. Young Indian gerbils are independent as early as 21 days of age and reach sexual maturity as early as 10 weeks of age. Females attain sexual maturity earlier than males.
Breeding interval: Indian gerbils can breed multiple times throughout the year, the interval is not well known.
Breeding season: Indian gerbils breed throughout the year, with peaks in February, July, August, and November.
Range number of offspring: 4 to 10.
Range gestation period: 21 to 30 days.
Range time to independence: 21 (low) days.
Range age at sexual or reproductive maturity (female): 10 (low) weeks.
Range age at sexual or reproductive maturity (male): 10 (low) weeks.
Key Reproductive Features: iteroparous ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous
Average birth mass: 3 g.
Average number of offspring: 5.4.
Parental care in T. indica has not been described. However, as in all mammals, females nurse and care for their young until they reach independence. The young are born in a relatively helpless state in a nest chamber in a burrow. Their eyes open at 14 days old.
Parental Investment: altricial ; female parental care
