Black bears are a common and native presence across Colorado’s forested mountains. Open occurrence databases hold 1,864 records for black bears in Colorado, most of them iNaturalist photos, spread along the Front Range foothills and the western slope.
Where and when to see black bears in Colorado
Look in montane and foothill forest with good cover and seasonal food. Sightings concentrate around White River National Forest, Grand Mesa National Forest, and Florissant Fossil Beds National Monument and the state’s other big national forests. The seasonal rhythm reflects a bear’s active calendar, not its true numbers: reports climb through spring, hold high through midsummer, then drop toward winter as bears move to their dens. A run of near-empty winter months is denning bears, not departed ones.
Status in Colorado
The black bear is native to Colorado and secure here, ranked S5 (secure) by NatureServe and least concern by the IUCN.
A Colorado field note
Western Rocky Mountain black bears often wear the brown or cinnamon color phase, so a “brown bear” in Colorado is almost always a cinnamon-phase black bear, not a grizzly. Grizzlies are considered extirpated from the state, which is exactly why color is a poor guide here and structure, no shoulder hump and a straight facial profile, is the real test.
Common questions
Are black bears common in Colorado? Yes. It is one of the state’s most-recorded mammals and lives in forested habitat statewide, from the foothills to the subalpine.
When are they most active? Through the warm months, peaking in midsummer, and far less so once they enter their winter dens.
