The Gray wolf
The gray wolf (Canis lupus) has over 32 subspecies that are found worldwide and range from across Europe to northern Asia, however most are located in North America. Gray wolves prefer to live in areas with a variety of topographic features such as forests, open meadows, lakes and rivers, and rocky ridges.
Wolves have occasionally been known to prey on free-range poultry. They will typically kill birds with a single bit over the back, leaving large canine tooth holes in the carcass. Multiple birds--if not all are likely to be killed. One wolf is capable of killing 50 to 100 birds in a single night. They will often return every few nights to prey on the flock again.
