Yellowstone euthanizes baby bison after human interference.

A bison calf was put to death by Yellowstone National Park officials after a visitor picked it up, causing the herd to reject it. The calf had become separated from its mother and was pushed up from the river by the unidentified man. Park rangers tried to reunite the calf with the herd but were unsuccessful. Visitors saw the calf walking up to and following cars and people, creating a hazard. Bison have gored several people in Yellowstone in recent years, often after they got too close to the animals.
