In late October, wildlife authorities in the U.S. state of California announced they captured and euthanized three adult gray wolves and shot a juvenile dead, all from the Beyem Seyo pack in the Sierra Valley. Wardens killed them, the California Department of Fish and Wildlife (CDFW) said, because the wolves (Canis lupus) had become “habituated to preying on cattle” rather than hunting elk, deer and other wild prey. The wolves killed were a breeding pair, an adult female, and a juvenile male “mistaken” for the adult male. Officers also found the remains of two other juveniles from the same pack that were severely decomposed. The cause of death remains unknown, and authorities are investigating. This pack took down at least 88 head of cattle between January and October 2025 according to a new CDFW report — about half of the 175 livestock deaths statewide and one of the highest rates in any western U.S. state where wolves live.
