We report apparent predation by coyotes (Canis latrans) on one of two male pronghorns (Antilocapra americana) that were locked together. When the locked pronghorns first were spotted at 2030 h, both were alive, one standing and the other on the ground wounded by a horn of his opponent. At ca. 0230 h, four coyotes were seen within 150 m of the pronghorns. At 0630 h, the wounded pronghorn had been partially eaten, presumably by the coyotes, and the other pronghorn freed himself from the carcass and walked away.
