Jackson, Wyo. • Wildlife managers have killed five wolves from a large pack that had been killing yearling cattle in western Wyoming.

The Dell Creek Pack numbered as many as 16 animals and repeatedly killed cows grazing on private ranchland in the Hoback River Basin southeast of Jackson this winter.

The Jackson Hole News & Guide reports (http://bit.ly/1QXCkGI ) that gunning from a helicopter has in recent weeks trimmed the pack down to 11 members.

U.S. Fish and Wildlife Service Northern Rocky Mountain Wolf Coordinator Mike Jimenez says that Dell Creek Pack hadn't started killing livestock until this winter.

Jimenez says large packs can be problematic because they need more food and can kill larger prey.
