Guilty plea for disturbing Yellowstone bison calf leads to fine.

A Hawaii man, Clifford Walters, pleaded guilty to a federal charge and was fined after he helped a bison calf, which was later euthanized after its herd rejected it in Yellowstone National Park. Walters helped a newborn bison calf out of the Lamar River, after the animal became separated from its herd. The calf was then rejected by the herd, which can happen when humans interfere with wildfire, according to the park. Walters was ordered to pay a total of around $1,000 in a fine and payment to the park's wildlife fund.
