Wolves killed a lamb and probably killed a calf in separate attacks in late May, Oregon Department of Fish & Wildlife reported.
On the evening of May 20, a herder working on private land along the South Fork of the Walla Walla River near the Umatilla-Wallowa county line noticed a disturbance in the flock and saw four wolves, one with a dead lamb in its mouth. ODFW personnel investigated the next day and confirmed the kill was done by wolves. Investigators found a “drag trail” of bone, blood and wool, but the rest of the lamb apparently had been consumed overnight. Tracking collar data showed that OR-40, of the Walla Walla Pack, was near the sheep bedding ground at 3 a.m. on May 21.
On May 23, a landowner checking cattle on private land in the Mud Creek area of Wallowa County found the remains of a dead calf. There was no clear evidence the 150-pound calf had been attacked by wolves, but marks on the rib, back and leg bones found scattered about the site indicated a predator with large teeth was responsible, according to an ODFW report.
In addition, the calf was consumed in one night, also hallmark of a wolf attack. Nonetheless, ODFW designated the incident a “probable” wolf attack rather than “confirmed.”
Tracking collar GPS coordinates showed two members of the Shamrock Pack, OR-23 and OR-41, were in the area at different times on May 22 and May 23.
