YELLOWSTONE NATIONAL PARK, Wyo. — Yellowstone National Park officials killed a newborn bison because its herd wouldn’t take the animal back after a man picked it up.
The calf became separated from its mother when the herd crossed the Lamar River in northeastern Yellowstone on Saturday. The unidentified man pushed the struggling calf up from the river and onto a roadway, park officials said in a statement Tuesday.
Park rangers tried repeatedly to reunite the calf with the herd but were unsuccessful. Visitors saw the calf walking up to and following cars and people, creating a hazard, so park staff killed the animal, according to the statement.
It’s the latest example of Yellowstone visitors getting in trouble or hurt after approaching bison. Park officials euthanized a newborn bison after a similar incident in 2016, when a Canadian man and his son put the calf in their SUV, thinking they could rescue it.
The man pleaded guilty. He was fined $235 and ordered to pay $500 to the Yellowstone Park Foundation Wildlife Protection Fund.
Bison have gored several people in Yellowstone in recent years, often after they got too close to the animals.
Many of Yellowstone’s larger animals — including bison, which can run up to 35 mph and weigh up to 2,000 pounds — are deceptively dangerous, even when they’re just grazing or resting.
Park rules require visitors to keep at least 25 yards away from wildlife including bison, elk and deer, and at least 100 yards away from bears and wolves.
Park officials are investigating the bison calf incident. The suspect was a white male in his 40s or 50s who was wearing a blue shirt and black pants, the statement said.
