Which prairie dog is listed on Wikipedia as an obligate hibernator?

The white-tailed prairie dog is listed as an obligate hibernator.

“Obligate” means that the species enters hibernation as part of its regular annual cycle, rather than only doing so when food is scarce or weather becomes unusually severe. White-tailed prairie dogs spend winter in underground burrows, where their metabolism and body temperature are greatly reduced.

The distinction matters because prairie dogs do not all handle winter alike. Black-tailed prairie dogs are generally described as facultative hibernators: they can remain active above ground and use shorter bouts of torpor, especially at night or during harsh weather. Utah and Gunnison’s prairie dogs also hibernate, but the canonical contrast in this classification is white-tailed versus black-tailed.

White-tailed prairie dogs live in western Wyoming and Colorado, with smaller areas extending into Utah and Montana. Their seasonal emergence is staggered: males typically appear first, followed by females several weeks later.
