Do Bears Eat Other Bears
Yes, bears sometimes eat other bears. Cannibalism is uncommon but documented in several species. It usually occurs when food is scarce or during intense competition for resources.
Why Bears Eat Other Bears
Bears may kill and consume other bears for nutrition, territory, or to eliminate rivals. Male bears sometimes kill cubs sired by other males, a behavior called infanticide. Starving bears are more likely to scavenge or hunt other bears.
Which Bears Are Most Likely to Eat Other Bears
Grizzly bears and polar bears are the most documented cases of bear-on-bear predation. Polar bears may kill and eat other polar bears, especially during food shortages on sea ice. Grizzlies occasionally prey on black bear cubs or weaker individuals. For more details on bear diet and behavior, visit https://www.nps.gov/subjects/bears/bear-diet.htm
