Snowshoe hares have a negative effect on moose as they eat some of the same vegetation that moose eat, which only contributes to the decline in appropriate forage for moose. [17] The red fox is yet another animal that inhabits Isle Royale; red foxes mainly feed on snowshoe hares and occasionally scavenge on moose, or any other meat a wolf ...
The bear may also pin its prey (usually young) to the ground and then immediately tear and eat it alive. [84] Despite being characterized as unskilled predators with minimally-refined hunting skills, most individual bears who are routine ungulate predators have shown the ability to vary their hunting strategy and have hunting success rates ...

Aggressive mimicry often involves the predator employing signals which draw its potential prey towards it, a strategy which allows predators to simply sit and wait for prey to come to them. The promise of food or sex are most commonly used as lures. However, this need not be the case; as long as the predator's true identity is concealed, it may ...
The moose calf crop has been declining since the fires of 1988. During that summer there was also high predation of moose by grizzly bears in small patches of surviving timber. The winter following the fires many old moose died, probably as a combined result of the loss of good moose forage and a harsh winter.
They prefer to prey on mule deer, but occasionally kill elk, white-tailed deer, and bighorn sheep, and in Alberta, moose kills have been documented. Recently, cougars have recolonized many areas where they were eliminated in the 1800s and early 1900s, and have greatly increased in number. [ 31 ]
