This is what the kittens will survive on for the next four to seven weeks.īaby chipmunks despite being born blind are still able to locate their mother’s teats in order to fasten on them. Soon after birth, mother lays down on her dorsal side or on either of her sides in order to suckle the newborns with warm, succulent and nutrient rich milk squirting impatiently from her teats. They weigh less than 4g at birth and are called kits, kittens or pups. Babies emerge with ventral side facing up and buttocks first. Females retire into their burrows, lay on their dorsal sides, on their buttocks, on either of their sides, or continuously rotate between these positions with legs spread out wide to support birthing.Īs the babies begin to emerge one after the other, (one litter can contain three to six babies depending on the species), the mother chipmunk continuously lick the naked, deaf and blind entities clean. For example, the Siberian chipmunk have a gestation period of 28 to 35 days whereas the least chipmunk gestate for 28 to 30 days.Īfter a complete gestation, it’s time for birth. Sperm meets eggs and fertilizes it, and females become pregnant for the duration of 25 to 40 days depending on species. Gestation in chipmunks lasts for about a month after copulation. She’s the hot cake, so she set the rules! All of the above showdown usually take place near the vicinity of the females burrow. Mating can last for as long as five minutes and as little as 15 seconds depending on species, and is usually characterized by intermittent breaks between each thrust sessions. The male then mounts on her from the rear and preforms 12 to 24 quick thrusts. Following that, the female becomes very interested and transitions into a squatting position. Just imagine the level of competition.Īfter the chirp call of the female, and show of dominance by the males (if more than one is present), the lucky guy who gets to mate with the “doer” continuously jumps around her in order to set her in the mood. When females emerge, mating takes place soon after because they enter into estrus within a week or two and are only receptive to males for a couple of days. A typical example is the eastern and western chipmunks of the southern United States.ĭuring winter season, all chipmunks retire into their well-constructed intricate burrows in order to take shelter from the biting cold, and in spring, males emerge out first, eagerly anticipating for receptive females emerging out from their dens one or two weeks later. Some species in favorable years can breed twice in a year, bearing and birthing one litter in fall and another in summer. On calendar, that‘s a span from February to mid June. Mating in chipmunks, depending on species, happens in winter, in spring and/or in summer as well. So both sexes aren’t monogamous or non-promiscuous and neither do they stick with a certain click of females each and every mating season. Males after mating with a certain female, also go out in search for potential partners elsewhere. More than one interested male party usually ends up being attracted to the chirp which lasts anywhere from ten to fifteen minutes, and thus, competitive edge is only guaranteed for the strongest and most intimidating of the pack.

Their birth is as swift as the colorful stripes that run along the length of their backs and weaning alongside maturity happens like it never took place in the first place. They only need warm milk, cozy burrow and timespan as brief as a whoosh in order to perform the magic. Chipmunk babies don’t take forever to transition from fetus to adults.
