Zoo American Black Bear Welfare: Enrichment and Hibernation

American black bears in zoos require complex foraging environments and appropriate winter management that supports their semi-hibernation physiology and behavioral needs.

Key Facts

Black bears undergo facultative hibernation — their body temperature drops less than true hibernators but they enter months-long torpor
Wild black bears forage up to 20 hours per day during hyperphagia before winter denning
They are omnivores with highly varied diets including berries, insects, fish, and carrion
Black bears are cognitively sophisticated with excellent memory for food locations
Despite being the most abundant bear species, some populations are threatened by hunting and habitat loss

Welfare Considerations

Black bear welfare in zoos benefits from complex foraging enrichment that matches their naturally high food motivation, particularly scatter feeding, puzzle feeders, and honey logs. Winter management must provide denning opportunity for bears that naturally hibernate — preventing appropriate torpor causes physiological and behavioral stress. Exhibit complexity with varied substrates, water features, and climbing structures supports natural behavior expression year-round.

What You Can Do

Support zoos with naturalistic black bear exhibits that include winter denning facilities
Advocate for bear-viewing tourism standards that prioritize welfare over maximal visibility
Oppose black bear trophy hunting in states where populations are declining
