mating behavior

View fullsize  Males 29 and 45 have a territorial dispute. Many females have emerged in their area, and they will dispute through the mating season, often fighting.  ©MRR 2017
View fullsize  During the mating season, adult males are evidently sexually mature, displaying pigmented testes and a distended scrotum.  ©MRR 2017
View fullsize  45 stands over Wetsuit at her burrow, anticipating her estrus.  ©MRR 2017
View fullsize  45’s pursuit of Wetsuit is relentless on the day she goes into estrus.  ©MRR 2017
View fullsize  45 brings nesting material to a burrow prior to mating with Wetsuit. Though not common, this behavior has been observed in mating males.  ©MRR 2017
View fullsize  45 lets out a mating call at the mouth of the burrow where he has chased Wetsuit. The mating call is sounded before and/or after mating, and if not for context can easily be mistaken for an alarm call.  ©MRR 2017
View fullsize  45 chases and herds 50 into her burrow. We call this a Chase Herd (scored as CH on a datasheet) and it is one of the most common interactions we track, occurring between males, between females, and males to females, though rarely females to males un
View fullsize  Generally a couple to a few days after mating, females will begin to exhibit maternal behavior, including carrying nesting material to potential nursery burrows. Gestation will last on average 28 days.  ©MRR 2017
View fullsize  After mating, 83 licks her vulva. This is one of several aboveground cues that signify a copulation has occurred.  ©MRR 2017
View fullsize  Despite this being her day of estrus, 83 is not ready and rebuffs 45 for now. On their day of estrus, females are only receptive for a few hours.  ©MRR 2017
View fullsize  24 has a very late wakeup and licks his penis (scored as LP on a datasheet) immediately upon emerging, indicating he spent the morning copulating with a female.  ©MRR 2017
View fullsize  Having already mated with her, 24 tries to keep 6 Stripe underground, chasing and herding her into her burrow to keep her away from other males in the area.  ©MRR 2017
View fullsize  After a male has had his Critical Underground Consortship (CUC) with a female (in which insemination occurs and which is characterized by disappearing underground together for many minutes up to hours), he usually does not go down with her for anoth

View fullsize  R21 chases 49 out of his territory on a day when 5SRS, a female in the area, goes into estrus.  ©MRR 2017
View fullsize  Some time after his first check, 2 comes back for another sniff at Wide Apart.  ©MRR 2017
View fullsize  Male 36 investigates female 90. Gunnison’s prairie dogs exhibit sexual dimorphism in body mass, and here you can see how much larger 36 is than 90.  ©MRR 2017
View fullsize  36 continues to pursue 90 to check for estrus, and she continues to elude him.  ©MRR 2017
View fullsize  RR0, a female who has already mated, brings nesting material to her burrow as she begins to show maternal nesting behaviors.  ©MRR 2017
View fullsize  A female runs away from a male trying to sniff her.  ©MRR 2017
