Yellowstone baby bison put to death after visitor picks it up, leading herd to reject it

Yellowstone National Park officials say they had to kill a newborn bison because its herd wouldn’t take the animal back after a man picked it up. Park officials say in a statement the calf became separated from its mother when the herd crossed the Lamar River in northeastern Yellowstone on Saturday. The unidentified man pushed the struggling calf up from the river and onto a roadway. Park rangers tried repeatedly 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, so park staff killed the animal.
