Black bears: typically avoid humans and often retreat. Most encounters end with the bear leaving once it detects humans. However, they may become more aggressive if:
- Protecting cubs
- Defending a food source
- Startled at close range
- Habituated to human food
Brown/grizzly bears: tend to be more aggressive than black bears, especially females with cubs. They may charge as a bluff or stand their ground to assess the situation.
Polar bears: are predatory and may view humans as prey. These encounters are rare but potentially the most dangerous.
The safety recommendations for bear encounters generally include:
- Making noise while hiking to avoid surprise encounters
- Carrying bear spray in bear country
- Not running if you see a bear (this can trigger chase instincts)
- For black bears: appearing large, making noise, and fighting back if attacked
- For brown bears: playing dead if attacked (lying face down, hands protecting neck)
Bear attacks are actually quite rare. Most wild bears prefer to avoid human contact, and many encounters end with bears simply moving away once they detect humans.
