White-tailed Prairie Dog (Cynomys leucurus) lives in grassland plains across Western North America. It feeds on grass and seeds. Its conservation status is Least Concern.
Fascinating facts about the White-tailed Prairie Dog
- White-tailed prairie dogs live high up on the Rockies, nesting between 5,000 and 10,000 feet (1,500-3,000 m), higher than any other prairie-dog species. This altitude forces them onto dry desert grasslands and sagebrush cover, shaping a diet of tough forbs and sedges that other low-land rodents can't digest. Their presence at these heights makes them a key indicator of climate-driven habitat change in the western U.S.
- Each colony spans roughly 54 acres and contains about 22 burrows per acre, organized into six distinct family "clans." These tight-knit groups coordinate vigilance, with sentinels perched on mounds to sound alarms. The clan structure means a single colony can still maintain a rapid response network that thwarts predators such as golden eagles and black-footed ferrets.
- Males surface from hibernation in late February to early March, and females follow 2-3 weeks later. Gestation lasts about 30 days, so pups arrive in late April-early May, stay underground for 5-7 weeks, and then emerge in early June. Litters average five young but can range from two to eight.
- By constantly digging, white-tailed prairie dogs turn over the soil, increasing its porosity and allowing water to seep deeper. This aeration creates richer grazing for American pronghorn and other herbivores, while also providing burrow shelters that black-footed ferrets depend on almost exclusively for food and refuge. Their engineering thus sustains an entire high-altitude food web, linking rodents, predators, and grazers.
- An adult white-tailed prairie dog weighs between 28 oz and 53 oz (790-1,500 g) and measures 12-16 in (30-41 cm) long. Males tip the scale at up to 1.7 kg while females are lighter.
