The herd would no longer accept the animal.
Rangers at Yellowstone National Park had to euthanize a bison calf after two well-meaning tourists loaded the animal into their rental SUV. The father and son thought the creature was cold and took it to the ranger station for help, according to East Idaho News in the video above. The story has gone viral online and forced the Yellowstone to issue a statement about what happened.
Rangers ticketed the men and forced them return the animal. Unfortunately, creature’s herd refused to accept it again. “The bison calf was later euthanized because it was abandoned and causing a dangerous situation by continually approaching people and cars along the roadway," Yellowstone National Park said on Facebook.
Many people were very angry that rangers killed the calf, and the park service has tried to address their concerns. According to the agency, bison in the park can carry the disease brucellosis, and “federal and state laws prohibit their shipment outside the park.” Rangers also don't consider rescuing animals part of their mission. “Our goal is to maintain the ecological processes of Yellowstone,” it said.
Despite their cuddly appearance, bison are very dangerous. According to Yellowstone, they injure more visitors there than any other animal. Rangers advise staying at least 75 feet away from them.
