Several predators prey on mountain beavers. Above ground, the main predator, when present, is probably the bobcat (Felis rufus). Coyotes (Canis latrans) and great horned owls (Bubo virginianus) are other major large predators. In burrow systems, mink (Mustela vison) and long-tailed weasels (Mustela frenata) are the main predators. Weasel predation is probably limited to young or subadult animals less able to defend themselves.
