sorry didn,t mean for it to sound like they were really stressed actually oppisite I have been flying around elk and it was said as a pun the animals were at ease so they have been around drones or as you say they were a long way off , I had a small herd of elkI followed for a month and at first they got a little boggered around the third or forth time i flew over they just looked up and then ignored the drone they got used to it fairly quickly and those cows are still in the same area I,ll be more careful how i say things Sir the was national geographic shooting you did there ,very nice
