Gunnison’s prairie dog belongs to New Mexico’s high northern grasslands, and its 2271 records keep to that ground. Valles Caldera National Preserve alone accounts for 420 of them, with the rest running through the northern mountain valleys and mesas, from the Jemez country of Sandoval County past Santa Fe and Taos to Colfax County’s Eagle Nest Lake and out to Aztec Ruins National Monument.
A town under the meadow
These prairie dogs live in colonies of family groups, each holding its own burrow system in open grassland, and they clip the vegetation around those burrows short to keep sightlines clear for predators. Sentries answer a coyote or a hawk with sharp alarm calls that send the whole town underground in seconds. Their cropped meadows and vacated burrows shelter and feed wildlife well beyond the prairie dogs themselves.
A true winter shutdown
The record nearly vanishes from November into February, and that gap is real behavior. Gunnison’s prairie dogs hibernate, retreating below ground and letting their body temperature fall through the coldest months. Colonies pour back to the surface in spring, and counts crest in June and July, when pups emerge and the town feeds through the long days.
Status in New Mexico
NatureServe ranks Gunnison’s prairie dog S2, Imperiled, in New Mexico and G3 globally. The species is native to the state, and despite its visibility in open meadows it holds its ground colony by colony, with whole towns vulnerable to plague and habitat conversion.
