Well, it just got a lot worse, rangers at Yellowstone just had to euthanize the baby bison. Apparently after they took him back to his herd, the herd wouldn't accept him, and abandoned him.

The calf started approaching cars, which was a safety issue. The park didn't have the resources to take care of him, and they couldn't ship him anywhere else for months because of a quarantine for a disease called brucellosis.
