Biologists with the Montana Fish, Wildlife and Parks department were looking for a female grizzly bear during August to use in a population augmentation program in the Cabinet Mountains. Instead, they caught two adult males, which were rereleased.

The second bear was definitely not happy with the experience, taking out his aggression on a trailer cage after being released. He showed, the department said, “why grizzlies must be respected.” Credit: MontanaFWP via Storyful
