The common raccoon is one of Colorado’s most familiar mammals. Open occurrence databases hold 1,925 records for it in Colorado, most of them iNaturalist photos, weighted heavily toward the cities and river corridors of the Front Range.
A generalist that thrives beside people
The raccoon’s masked face and ringed tail are unmistakable, and its success comes down to eating almost anything and living almost anywhere with water and cover. That is why the densest records fall in the populous Front Range counties, Boulder, El Paso, Larimer, Adams, Arapahoe, and Denver, where the animal works storm drains, greenbelts, and the wooded banks of the South Platte with equal ease. Its nimble, almost hand-like forepaws let it open, pry, and manipulate food that stumps other carnivores.
Active by night, busiest in spring
Raccoons are strongly nocturnal, so most sightings come from trail cameras, evening encounters, and animals caught out at dawn. The record climbs through spring and early summer, when adults range widely and that year’s young begin moving on their own, then settles over the colder months as raccoons wait out hard weather in dens. They do not truly hibernate, but they den up and slow down when it turns bitter.
Status in Colorado
The raccoon is native and secure here, ranked S5 by NatureServe and least concern by the IUCN, and it is one of the mammals a Coloradan is most likely to meet without ever looking for it.
