Ord’s kangaroo rat is a rodent in Colorado. Open occurrence databases hold 1,975 Colorado records, yet only 66 are iNaturalist photos. The bulk are museum specimens and small-mammal trapping surveys, the expected trail for a nocturnal desert rodent that rarely poses for a camera.
A specialist of sandy ground
Ord’s kangaroo rat is built for loose, sandy soil, and its Colorado records map onto exactly that. Weld County alone accounts for hundreds of records off the sandsage prairie of the Pawnee country, and the animal follows sandy ground out across the eastern plains through Logan, Yuma, Las Animas, and Baca counties, then reappears in the dune fields and sandy valley floor of the San Luis Valley around Alamosa, Saguache, and Costilla, and the sands near Great Sand Dunes. It hops on long hind feet like a tiny bipedal rodent, digging burrows in the sand and living on seeds it gathers into fur-lined cheek pouches, needing almost no free water because it wrings moisture from its dry seed diet.
Nocturnal, and quieter in the cold
This is a strictly night-active animal, so nearly every record comes from after dark, by trapping or by headlamp. Through the coldest stretches of the Colorado winter it does not truly hibernate but goes quiet, staying below ground and dropping into torpor to save energy, then living off the seed caches it stored in fall. That is why observations thin out in the cold months and build again once nights warm. The gap is the animal conserving energy underground, not leaving.
Status in Colorado
Ord’s kangaroo rat is native to Colorado and ranked S5 by NatureServe, secure across the sandy plains and valleys, and globally Least Concern. To find one, go to open sandy grassland or dune country after dark and watch the ground ahead of a headlamp for the long-tailed, bounding hop that gives the kangaroo rat its name.
