Watch: Yellowstone coyotes 'duke it out' over prize buried in snow

A guide leading a tour in Yellowstone National Park this week captured dramatic footage showing two coyotes battling over a presumed bison carcass buried in the snow.

The accompanying footage, captured by Yellowstone Wolf Tracker guide Michael Sypniewski, begins with one coyote launching an attack on the other coyote as it attempted to feast on the carcass.

Wolf Tracker’s description: “A couple mornings ago, Wolftracker guide @michaelwsyp and his guests watched two coyotes duke it out along the Lamar River. This intense back and forth battle went on for close to 10 minutes!”

The description continued: “Although obstructed from [the tour group’s] view, they believe the two canines were fighting over the remains of a bison carcass buried deep in the snow.”

The footage appears to show that the coyote already on the carcass was the dominant combatant.

As winter turns to spring, many of Yellowstone’s critters rely on frozen carcasses, revealed by melting snow, for sustenance.
