The Oregon Department of Fish and Wildlife has confirmed that wolves from the Imnaha pack have killed a yearling cow and injured a calf.
The department in a press release said radio collar evidence shows wolves from the pack were present at the site of both attacks.
The incidents are the third and fourth confirmed wolf depredations by the Imnaha pack in 2013.
The northeast Oregon pack has been involved in more than two dozen depredations in recent years.
A court injunction is currently blocking a state order to kill two wolves from the pack.
The pack is one of six known packs in Oregon, and one of only two Oregon packs known to be involved in depredations.
