YELLOWSTONE NATIONAL PARK, Wyo. — A newborn bison at Yellowstone National Park quickly learned how dangerous the world can be.

A coyote tried to attack the bison calf before it could even stand, park officials said on Facebook.

Last week, immediately after a cow bison gave birth, the coyote went in for the kill.

Park ranger Joy Duffy captured images of the attack but did not intervene, which is park policy.

“The cow was worn out from giving birth and the calf was unable to stand yet,” park officials said.

Officials said the coyote was “very determined,” but the cow bison protected her calf until the coyote eventually gave up.

Park officials noted “all three appeared to be exhausted from the interaction.”

Multiple people questioned why park officials didn’t try to stop the attack or help the cow and her calf.

“Death is an unpleasant, but necessary, part of nature,” park officials responded. “Yellowstone is not a zoo or an animal park. It can be difficult to watch nature take its course, especially when young animals are involved.”
