Drones playing AC/DC and human voices are used to ward off wolves near cattle in California.

Biologists are using drones equipped with speakers to play AC/DC music and human voices to scare wolves away from cattle near the California-Oregon border. This non-lethal method aims to protect livestock as the wolf population has grown, leading to conflicts with ranchers. Although the drones have shown success in deterring wolves, concerns exist about wolves becoming accustomed to the noise and the high cost of the technology.
