I can tell you have never worked on a ranch.
Actually, I did work on a ranch for awhile in college. We had motion-sensitive lights and air canons strategically placed to scare off the coyotes and cats. We also had a "hazer" who came by once a month to check for scat and to move the noisemakers as necessary. From what I gather, they've retired the noisemakers now since they put in windmills for power. The ultrasonics seem to keep away a lot of the wildlife.
