Fat Bear Week delayed after a large bear kills a rival bear

Fat Bear Week, a celebration of brown bears’ survival instincts, brought a grisly reminder of the animals’ predatory nature on Monday, when a male bear, 469, killed a female, 402, at Katmai National Park & Preserve in Alaska.

The unsettling scene was captured by a popular live webcam that follows the bears on the Brooks River.

In a statement sent to NPR, the park said, “National parks like Katmai protect not only the wonders of nature, but also the harsh realities. Each bear seen on the webcams is competing with others to survive.”
