Black Bears in Estes Park | Wildlife Guide

Overview

Colorado's native bears are American black bears.

Rocky Mountain National Park states that only black bears are known to exist in the park and that grizzly bears are no longer found in Colorado. Despite the name, black bears can be black, brown, cinnamon, blond, or honey-colored.

Black bears usually avoid people, but food rewards can overcome that natural wariness. Colorado Parks and Wildlife reports that most human-bear conflicts are connected to garbage, human food, pet food, bird seed, and other attractants.

Wildlife is one of the greatest treasures of Estes Park. Observe from a safe distance, respect natural behavior, and help preserve these remarkable animals for future generations.

Wildlife Wisdom

A fed bear is a bear in danger.

Preventing access to food is the most effective way to reduce conflict around homes and businesses.

01 · REMOVE REWARDS

Do not let a bear succeed

A single food reward can encourage a bear to return to the same property or neighborhood.

02 · SECURE FIRST

Prevention works before a sighting

Trash, grills, pet food, bird seed, compost, and coolers should be managed before bears become active.

03 · KEEP DISTANCE

Never approach for a photograph

Use binoculars or a long lens and allow the bear a clear escape route.

Seasonal Behavior

Bear activity follows food, weather, and denning cycles.

Exact timing can shift from year to year.

SPRING

Emergence and renewed feeding

Bears leave winter dens and begin searching for available natural foods. Human attractants can become especially tempting when natural food is limited.

SUMMER

Active feeding and movement

Bears may travel widely in search of natural foods and water. Unsecured trash, pet food, grills, and bird feeders can draw them into developed areas.

FALL

Intense pre-den feeding

Bears increase food intake before winter. Attractants around homes and businesses become particularly risky during this period.

WINTER

Denning

Many bears spend winter in dens, but den timing varies. A bear disturbed near a den should be given space and reported if there is an immediate safety concern.

DROUGHT YEARS

Natural food shortages increase conflict

Colorado Parks and Wildlife notes that reduced natural food can increase human-bear conflict.

YEAR-ROUND

Do not leave attractants accessible

Consistent prevention is more reliable than waiting until a bear appears.

Living with Bears at Home

Most conflict prevention begins with attractant control.

Homes, rentals, garages, decks, and outdoor storage areas should all be reviewed for bear access.

01 · TRASH

Use wildlife-resistant practices

Follow current Estes Valley trash-storage rules and keep refuse inside an enclosed structure or approved container as required.

02 · BIRD FEEDERS

Seed is a powerful attractant

Bird seed can attract bears directly or draw other animals that create additional wildlife activity.

03 · PET FOOD

Feed indoors when possible

Do not leave pet food, bowls, or feed-storage containers accessible outdoors.

04 · GRILLS

Clean and store carefully

Grease, food residue, drip pans, and nearby trash can attract bears.

05 · FRUIT AND COMPOST

Manage seasonal food sources

Ripe fruit, fallen fruit, compost, livestock feed, and unsecured garden materials can attract bears.

06 · DOORS AND WINDOWS

Secure access points

Keep garage doors closed, lock accessible doors, and avoid leaving food near open windows or screened openings.

If You See a Bear

Stay calm, do not run, and give the bear space.

Rocky Mountain National Park provides specific encounter guidance.

01 · STOP

Do not run

Running can trigger pursuit. Stay calm and assess the bear's location and escape route.

02 · GATHER PEOPLE

Pick up small children

Keep the group together and prevent anyone from moving closer.

03 · MAKE YOURSELF KNOWN

Use a firm voice

NPS guidance says to make noise, shout, or clap while remaining calm and backing away slowly.

04 · BACK AWAY

Leave the bear an exit

Do not corner the bear or block its route.

05 · STAND TALL

Do not crouch or play dead

For black bear encounters, NPS advises standing tall and fighting back if an attack occurs.

06 · REPORT DANGER

Use wildlife professionals

Contact Colorado Parks and Wildlife or local law enforcement for aggressive, injured, trapped, or dangerous bears.

Bears and Pets

Pets can escalate an encounter quickly.

Control pets and avoid allowing them to chase, bark at, or approach bears.

01 · LEASHES

Keep dogs controlled

A loose dog may chase a bear and then return to its owner with the bear following.

02 · NIGHTTIME

Check the yard first

Use lights and look outside before letting pets out after dark or near dawn.

03 · FOOD BOWLS

Bring them inside

Outdoor bowls and spilled food can attract bears and other wildlife.

04 · FENCING

Do not rely on ordinary fences

Black bears are capable climbers and may cross many residential fences.

05 · SMALL PETS

Supervision matters

Keep small pets close and do not leave them unattended in areas with wildlife activity.

06 · NEVER INTERVENE

Do not physically separate animals

Call the appropriate authority if a pet and bear encounter creates an immediate danger.

Conservation Context

Preventing food rewards protects both people and bears.

Colorado Parks and Wildlife explains that bears that become comfortable around people can damage property or threaten safety. Habituated bears may ultimately be killed. Preventing access to human food is therefore a direct conservation action.

Larimer County's Wildlife Protection Ordinance and the Town of Estes Park's related requirements are designed to reduce wildlife access to refuse across the Estes Valley.
