The life-saving potential of drones has been proven in plenty of successful search and rescue missions around the world, from Iceland to Australia.
The technology is now being used to save animals, too. In Graubünden in eastern Switzerland, drones with thermal imaging cameras were able to spot and rescue 450 newborn deer playing a high-stakes game of hide and seek in meadows and pastures due to be harvested.
Throughout the season across the area, around 1,100 missions saved 450 fawns during pre-harvest inspections using drones and thermal cameras. The fawns tend to lower themselves to the ground when a mower approaches, giving farmers little chance to spot them in time.
The drones have been brought in as part of a wider campaign to protect the animals during the Spring harvest.
