Drones bring the cows home in Lisbon

Drones have become essential for bringing cattle into the barn during this winter's deep snow,' said David Zufall of Lisbon. 'The accumulation of snow has made it nearly impossible to bring the cows inside with a four-wheeler or side-by-side without getting stuck, even with a tractor's tire path. Since the last snowstorm, I've successfully been using a drone to guide the cows inside for the night, and it has worked remarkably well.' Photo taken on the Zufall Farm in Lisbon, by David Zufall.
