Yellowstone bison calf euthanized after park visitors picked up animal on road

A calf that two men picked up in their SUV because they thought it was 'freezing' was put to sleep after it was rejected by its herd upon returning

A newborn bison calf that was picked up and put into the back of car because someone thought it was cold has had to be euthanized, prompting the National Parks Service to criticize a spate of "inappropriate, dangerous and illegal behavior" by visitors to Yellowstone.

Last week two visitors, reportedly a man and his son, were admonished by Yellowstone rangers after they picked up a baby bison and placed it into the back of their SUV. The bison was driven to a ranger due to concerns that the animal was cold.
