A bison calf was euthanized after two tourists put it in their car trunk last week in the Yellowstone National Park.
The tourists, described as foreigners, drove the calf to a park ranger station because they thought it was cold, eastidahonews.com reported.
They were ticketed and escorted back to release the calf where they found it.
But despite multiple attempts by the rangers, the calf was rejected by its herd. Because it kept approaching people and cars, it had to be euthanized.
The tourists seemed unaware of any problems in their behavior, according to Karen Richardson, who encountered the tourists while she was escorting children on a field trip.
“They were seriously worried that the calf was freezing and dying.” she told eastidahonews.com.
Visitors are not allowed to get within than 25 yards of large animals, like bison, or 100 yards for bears and coyotes, according to the park’s website.
Bison can run three times faster than humans and every year some people get gored. Some fatally.
The American Bison, also known as the buffalo, was officially designated the National Mammal of the United States on May 9.
