Colorado’s black bears are flooding into neighborhoods at record rates — and drought is only part of the story
In many Colorado mountain towns, black bears and people have shared the same forest edges and neighborhood perimeters for generations — an uneasy truce built on habit and mutual avoidance. But something shifted in 2026.
Reported bear sightings filed with Colorado Parks and Wildlife hit more than 6,000 between January and mid-August — nearly twice the number from the same period last year. Communities that once managed the occasional ransacked trash can are now contending with a surge that wildlife officials say is unlike anything they’ve tracked before. The bears aren’t lost. They’re hungry, and they’re running out of options.
A record year that caught Colorado off guard
More than 6,000 bear sightings were reported to Colorado Parks and Wildlife between January and mid-August 2026. That figure is nearly double the count from the same stretch in 2025, and the year isn’t over. Wildlife officials say 2026 is on track to become the most active year for bear-human encounters the state has ever recorded.
Black bears have always appeared in Colorado neighborhoods — mountain communities have managed the occasional raided trash can or backyard intruder for decades. The current surge, though, is operating on a different scale entirely, one that has caught even experienced wildlife managers off guard.
Officials point directly to drought. Serious, widespread drought conditions have stripped forest floors of the natural foods bears depend on, pushing them toward the nearest reliable calorie source: human neighborhoods.
Hyperphagia: the biological pressure behind every bear sighting
Understanding why bears are so persistent means understanding what their bodies are demanding right now. In late summer, black bears enter a state called hyperphagia — an extreme phase of food intake driven by the biological need to build fat reserves before hibernation. A bear that fails to accumulate enough fat before winter risks not surviving it.
During hyperphagia, a bear may need to consume up to 20,000 calories per day. That’s roughly 672 acorns, seven pounds of sunflower seeds, or 100 donuts — every single day.
Under normal conditions, bears meet this demand through berries, acorns, and grasses. Drought eliminates those options. Low snowfall and early snowmelt create dry conditions that persist through spring and summer, wiping out the natural food supply precisely when bears need it most. With the forest offering little, residential areas become the next logical destination.
A trash can, a bird feeder, or a backyard fruit tree isn’t just an opportunity — for a bear in hyperphagia, it’s a survival necessity.
Will rain fix it? Scientists aren’t so sure
The intuitive fix seems simple: bring the rain back, restore the food, and bears will return to the forest. Wildlife scientists, though, are cautious about that assumption.
Historical data does offer some encouragement. In previous years, summer monsoons correlated with strong fall acorn crops, and bear-human encounters dropped as a result — a pattern suggesting rainfall can make a real difference over time, A-Z Animals posted.
Timing is the problem. Summer rains may arrive too late to replenish food supplies within the narrow window that hyperphagia demands. Food availability doesn’t recover the moment rain falls; plants and trees need time to respond, and bears don’t have that luxury. What scientists consistently emphasize is that human behavior remains the most controllable variable — securing attractants, removing food sources, reporting sightings early. These actions reduce conflict in ways that weather simply can’t guarantee.
Colorado’s statewide response: education, grants, and early reporting
Colorado Parks and Wildlife hasn’t waited for the weather to improve. The agency joined BearWise, a public education program run by the Association of Fish & Wildlife Agencies focused on reducing the temptations that draw bears into neighborhoods. Residents are encouraged to secure trash, remove bird feeders, bring in pet food, and keep grills clean.
Beyond education, CPW’s Human-Bear Conflict Reduction Grant program has put real money to work. Since its launch, the program has distributed nearly $3.9 million to Colorado communities. In 2025 alone, 22 grants totaling $1 million were awarded — funding bear-resistant trash cans, electric fencing for chicken coops and beehives, and efforts to clear fallen fruit before bears find it.
Early reporting matters too. When residents flag sightings quickly, wildlife officials can intervene before a bear becomes habituated to human contact. A habituated bear is far harder to manage, and relocation often isn’t a viable option at that stage.
Face to face with a black bear: what experts say to do
If you encounter a black bear, the instinct most people follow is exactly what wildlife officials advise against. Running can trigger a chase response. Don’t do it.
Stay calm. Speak in a loud, steady voice, clap, shake your keys, make your presence impossible to ignore. Back away slowly and give the bear a visible escape route — most bears, given the chance, will take it.
Carry bear spray in bear country, but treat it as a last resort, deployed only when the animal is within effective range. If a black bear actually attacks, fight back. Unlike grizzly encounters, playing dead isn’t recommended here; passive behavior can make the situation worse.
As 2026 continues to set records, wildlife managers will keep watching monsoon patterns, acorn crops, and sighting numbers. The most immediate line of defense, though, runs through individual choices — made every day, in every neighborhood where bears and people share the same landscape.
