## Key facts: Black Bear
- Black bears are the most common bear in North America, numbering 800,000 or more.
- Coat colour varies — black, cinnamon, blonde and white (spirit bear) — despite the name.
- Black bears lack the shoulder hump of grizzlies and are generally smaller and less aggressive.
- They are skilled climbers and often escape danger by ascending trees.
- Human food attractants — bins, bird feeders, pet food — are the main cause of conflict.
- Populations are increasing in many eastern US states as forests recover.

## Identification and colour morphs
American black bears are smaller than grizzlies, with no shoulder hump, a straight facial profile, shorter claws and prominent ears. Fur colour is highly variable: most bears in the eastern United States are black, while western populations include cinnamon, blonde and brown morphs. The Kermode bear of coastal British Columbia carries a recessive gene producing white or cream fur — the 'spirit bear' revered by First Nations.

Colour alone does not distinguish black bears from grizzlies; body shape, hump presence and claw length are more reliable. Black bears are adept climbers, particularly juveniles, which retreat up trees when threatened.

## Ecology and behaviour
Black bears are omnivorous generalists. Spring diet includes emerging vegetation and carrion; summer brings berries, nuts and insects; autumn is dominated by calorie-rich foods such as acorns and beechnuts to build fat reserves for winter. They enter dens — hollow trees, rock cavities or excavated burrows — and enter a state of torpor, though not true hibernation.

Females give birth in the den to one to four cubs. Home ranges vary from roughly 5 km² for females in rich habitat to over 500 km² for males in sparse country. Black bears are mainly crepuscular and avoid open areas during daylight where hunting pressure is high.

## Living alongside black bears
As black bear populations recover in the eastern United States, encounters with suburban and exurban residents increase. Bears are attracted to rubbish bins, bird feeders, barbecue grease and pet food left outdoors. Once habituated, they lose fear of people and may damage property. Wildlife agencies recommend bear-proof bins, removing feeders in spring, and never feeding bears intentionally. Relocation rarely works for food-conditioned animals. Regulated hunting in many states helps manage population density and fund conservation. Education programmes — such as 'BearWise' — reduce conflict by teaching communities coexistence practices.

## Conservation status
The IUCN lists the American black bear as Least Concern with an increasing population trend in much of its range. Louisiana black bear (Ursus americanus luteolus) was delisted from the US Endangered Species Act in 2016 after recovery. CITES lists most populations on Appendix II. Habitat fragmentation and road mortality suppress local populations, but overall numbers are robust. The species serves as a model for how large carnivores can recover when hunting is regulated and forest habitat returns. Continued public education on attractant management remains essential as bears and people share more landscape.

## Frequently asked questions: Black Bear
### How can you tell a black bear from a grizzly?
Black bears lack the shoulder hump, have a straighter nose profile, shorter claws and more prominent ears. Grizzlies have a dished face and prominent hump. Fur colour is unreliable — both species vary.

### Are black bears dangerous?
Black bear attacks are rare. Most bears flee when encountered. Problems arise when bears become food-conditioned and lose fear of people. Securing rubbish and removing bird feeders prevents most conflict.

### What is a spirit bear?
The Kermode or spirit bear is a white colour morph of the American black bear found in coastal British Columbia. A recessive gene produces cream-coloured fur. Roughly 10% of bears on some islands are white.

### How many black bears are in North America?
The IUCN estimates more than 800,000 American black bears across Canada, the United States and Mexico, with populations increasing in many eastern US states.

### Do black bears hibernate?
Black bears enter dens and enter torpor over winter, slowing metabolism but remaining capable of waking. Pregnant females give birth in the den. Duration varies by latitude — shorter in the south, longer in the north.

### What do black bears eat?
Black bears are omnivores eating berries, nuts, insects, carrion, fish and occasionally deer fawns. Diet shifts seasonally; autumn feeding builds fat reserves for winter denning.
