How could a drone help a deer?
By indicating to farmers who are operating heavy equipment where deer might be hiding and resting in their fields. Many deer are killed instantly or lose limbs when they're run over by farming equipment, by farmers who have no idea they're there. What a wonderful use of drones! Video Link. It's a Swiss TV news segment, and includes some other interesting new technologies Swiss farmers are using. (thanks, @DeerRehab)
