The gray wolf is at the top of its food chain and serves as an alpha predator with no natural enemies or direct competitors once it reaches its adult size. Wolves hunt in packs and can bring down game much larger than themselves, preying on everything from small animals like rabbits and pheasants to much larger ones like elk and moose.
Gray wolves are threatened only by other gray wolves and by human poaching and encroachment onto their territory. Wolf habitats have suffered substantial damage at the hands of human enterprises, such as logging and farming operations that drive wolves from their hunting grounds and can cause them to starve.
Wolves are social animals who depend on one another for help and support. They also hunt together, communicating through a complex system of barks and other vocalizations to collaborate in exhausting large prey and driving it to death over a long distance and length of time.
Wolves kill by nipping at their prey until blood loss weakens it and it collapses or else stands to fight. Wolves have dull claws but powerful jaws and bite muscles which allow them to cling tenaciously to their prey until they drag it to the ground where the pack can dispatch it.
