. Males usually occupy larger home ranges compared to females, and interactions between individuals are very rare. Tamarisk jirds breed between March and October, usually producing 2–3 litters. Young jirds first emerge from their burrows between May and June, and they quickly disperse, rarely interacting with their siblings and mother. Tamarisk jirds reach sexual maturity at 70 days, but young males do not mate in their first year of age. For young females, less than half have been observed to breed in their first year of age, and this delay has been proposed to be associated with their delay in migration from their birth site.
