Living with Bears
Most conflicts between people and bears can be traced to human food, garbage, pet food, bird seed or other attractants. When people, intentionally or unintentionally , leave food out for bears to find, a bear’s natural drive to eat can overcome its wariness of humans. Bears that get too comfortable around people can destroy property or even become a threat to human safety. Habituated bears often must be killed.
By educating yourself and your neighbors, humans can live responsibly with bears.
Black Bear Behavior
Mothers with Cubs: Breeding
After a two- to three-month gestation period, a mother bear gives birth to one to three tiny cubs in mid-winter, typically while she’s still hibernating. Newborn cubs — weighing less than a pound at birth — are blind, toothless and covered with very fine hair. When they emerge from the den in early or mid-May, they will weigh 10 to 15 pounds. Cubs stay with the mother bear for their first year, denning with the mother and littermates over the winter. By the time of their second spring, they will be self reliant and will separate from their mother by the second autumn.
Despite popular misconceptions, mothers with cubs rarely attack humans. — but it’s never a good idea to get between a mother and cubs. Mothers will often perform a bluff rush to scare potential threats while the cubs will climb trees or other tall objects to escape the danger. If cubs become separated from their mothers, they can become lost and fall victim to vehicle collisions or predators.
Feeding and Hibernation
Over 90% of a bear’s natural diet is grasses, berries, fruits, nuts and plants. The rest is primarily insects and scavenged carcasses. With a nose that’s 100 times more sensitive than ours, a bear can smell food five miles away.
Most Colorado bears are active from mid-March through early November. In the fall, bears enter a period of compulsive overeating (hyperphagia). They start feeding for 22 hours a day to gain the 20,000 calories a day they need to survive hibernation. Bears will work hard to get the calories they need, and can easily damage property, vehicles and homes. Bears are very smart, and have great memories — once they find food near homes, campgrounds, vehicles or communities, they’ll come back for more.
Signs a Bear Feels Threatened
- Huffing
- Popping jaw
- Stomps a paw
- If your presence causes the bear to look up or change its behavior in any way, you are too close.
What Do you Do if You Encounter a Bear?
While on patrol, officers come in frequent contact with the public and will often perform customer service duties, including answering questions on regulations, recreational opportunities and other topics.
Black bears are highly intelligent and respond uniquely to people and situations. Black bears seldom “attack” or behave truly aggressively, but will fight back if they feel threatened.
When hiking in bear country, it’s smart to keep a few tools on hand for the possibility of running into a bear:
- A can of bear spray
- A whistle
- A tin can of coins, rocks or anything that will make noise when shaken
If a bear comes near your home, do your best to safely chase it away. Yell, blow a whistle, clap your hands, shake a tin can full of coins or rocks, or make other loud noises — but never approach a bear.
If a bear enters your home or yard, deterrents can be useful in areas.. The purpose of deterrents is to. persuade exploring bears to move on. For a list of deterrents that will make your home less attractive to bears, see the "Dealing with an Intruder" section of the Keep Your Home Safer for Wildlife page.
A bear that knowingly approaches a person could be food-conditioned and looking for a handout; it’s very rarely an aggressive bear. Don't feed this type of bear — instead, stand your ground. Yell or throw small rocks in its direction. If the bear continues to approach, get out your bear spray and use it when the bear is about 40 feet away. If you’re attacked, don’t play dead. Fight back with anything available. People have successfully defended themselves with pen knives, trekking poles and even bare hands.
Who Do You Call About an Aggressive Bear?
If you have an encounter with a black bear, immediately contact Colorado Parks and Wildlife, Monday through Friday, 8 a.m. to 5 p.m. Before or after these hours, contact the Colorado State Patrol or your local Sheriff's department. If a person is injured by a coyote, call 911 immediately.
Tips for Living with Bears
Avoid Attracting Bears to Your Home
Leaving attractants, like trash cans and bird feeders (hummingbird, suet and seed), out where they are accessible to bears is a violation of state law, as well as some local city and county ordinance. Always keep trash indoors overnight.
Tips for Keeping Bears Away from Your Home
Crossing Paths with Bears
Never approach bears or offer food. If you’re lucky enough to see a bear, watch from a safe distance. Stand still, stay calm and wait for the bear to leave. Be sure the bear has an opening to leave the area. Never run or climb a tree.
What You Should Do When You See a BearProtecting Pets from Bears
Keep dogs leashed; exploring canines can surprise a bear. Your dog could be injured — or come running back to you with a bear on its heels. Always supervise your pet when outside, especially at dawn or dusk when wildlife are most active.

Camping with Bears
Most campsites west of 1-25 are in bear country. When bears learn that people have food, they routinely visit camp sites, picnic areas and resorts in hopes of finding an easy meal. If you want to avoid problems for yourself and the bears, make sure there’s nothing to attract bears to your camp.
