Bears are the largest land carnivores on Earth, yet most of them eat more berries than meat, sleep away half the year, and would rather avoid you than meet you. Eight species roam the world’s forests, mountains, and sea ice — from a 100-pound sun bear to a 1,500-pound Kodiak brown bear — and North America alone holds close to a million black bears. Whether you found this page because you’re curious what bears eat, worried about meeting one on a trail, or trying to tell a black bear from a grizzly, this hub organizes everything we’ve written about bears in one place.
Start with the species profiles below, then dig into the side-by-side black bear and brown bear library — the two species North Americans actually encounter — and finish with the safety section, which is worth reading before any trip into bear country.
Meet the bear species
Taxonomists recognize eight living bear species. Our species library profiles them — along with several famous subspecies and color phases that are often mistaken for separate species.
| Bear | Where it lives | Profile |
|---|---|---|
| American black bear | North America | American black bear (Ursus americanus) |
| Brown bear (incl. grizzly) | North America, Europe, Asia | Brown bear (Ursus arctos) |
| Polar bear | Arctic sea ice and coasts | Bears of the Arctic |
| Asian black bear | Southern and eastern Asia | Asian black bear (Ursus thibetanus) |
| Sloth bear | Indian subcontinent | Sloth bear (Melursus ursinus) |
| Sun bear | Southeast Asian rainforest | Sun bear (Helarctos malayanus) |
| Andean (spectacled) bear | South American Andes | Andean bear (Tremarctos ornatus) |
| Kodiak bear | Kodiak Archipelago, Alaska | Kodiak bear (brown bear subspecies) |
| Siberian brown bear | Siberia and the Russian Far East | Siberian brown bear (brown bear subspecies) |
| Kermode “spirit” bear | Coastal British Columbia | Kermode bear (white black bear) |
| Cinnamon bear | Western North America | Cinnamon bear (brown-phase black bear) |
The eighth species — the giant panda of central China’s bamboo mountains — is a true bear too, and its profile is coming to the species library soon. For a tour by region, see our roundups of the bears of Asia, the bears of South America, and the bears of the Arctic. Wondering which bear is hardest to find in the wild? We ranked the rarest bears on Earth, and covered polar bear population trends and recovery efforts in depth.
Black bears vs. brown bears: the side-by-side library
Almost every bear question we get is really a question about one of two animals: the American black bear or the brown bear (which includes the grizzly). We’ve answered the big questions for both species, so you can compare them line by line.
Diet, foraging, and the hibernation myth
Bears are opportunists with a sweet tooth. Beyond the species diet guides above, we’ve profiled what’s in a grizzly’s diet, what polar bears eat on the ice, and the berry-obsessed “blueberry bears” of late summer. What makes all that foraging possible is the nose: a black bear can smell food from well over a mile away — which is exactly why food storage rules exist in bear country.
And the classic campfire debate — do bears really hibernate? — turns out to be more interesting than a yes or no. Bears enter a state many biologists call torpor or “carnivore lethargy”: body temperature drops only modestly, yet they go months without eating, drinking, or passing waste, and can rouse quickly if disturbed. The species guides on black bear and brown bear denning cover the timelines.
Bear safety: encounters, deterrents, and nuisance bears
Bear attacks are rare, but the right response depends on the species and the situation — which is why knowing your bears matters. Start with the honest risk assessments — how dangerous black bears really are, how dangerous brown bears are, and which bear is the most dangerous to encounter — then learn the encounter playbooks:
- What to do if you run into a black bear — stand your ground, look big, back away slowly; never run.
- What to do if you run into a grizzly bear — a different playbook, and the one situation where playing dead can be right.
- The best bear sprays for hiking — the single most effective deterrent you can carry.
- Dealing with black bears and dealing with brown bears around camps and property.
- Keeping black bears away and keeping brown bears away from your home — garbage, bird feeders, and pet food are the usual culprits.
- Managing nuisance black bears and nuisance brown bears when a bear has already learned bad habits.
The pattern behind nearly every conflict is the same: a bear got a food reward from people. Secure attractants and most bear problems never start.
Populations and where the bears are
North America’s black bear story is a conservation success — see the current black bear population in North America. For state-by-state curiosity, we’ve counted Maine’s black bears (the most in the eastern U.S.), mapped where black bears live in Texas, and settled which state has the most brown bears (it isn’t close — Alaska runs away with it).
Bear hunting and bear meat
Bear seasons are tightly regulated and vary widely by state. Our hunting section covers how to prepare for bear season, the black bear hunting laws in New England, the laws protecting Pacific Coast grizzlies, and rifle choices for big bears. If a hunt succeeds, don’t waste the harvest — bear meat is excellent when cooked properly (and must always be cooked through). Deer hunters will find plenty of crossover skills in our deer hunting hub.
Bears and deer
On a deer site, the obvious question: do bears hunt deer? Adult deer are usually too fast to be worth a bear’s effort, but bears are significant opportunistic predators of fawns in early summer, and they’ll claim any carcass they find. We cover the relationship in do black bears eat deer? — and you can see where bears rank among deer predators in what eats deer.
