No, they wanted him to work on coyotes all year long but him and his dogs were supposed to specialize in denning coyotes. I also specialized in denning coyotes as I found that to be about the best control method. But my real specialty was taking the older smarter coyotes that others had tried and not gotten yet. Him and his dogs were being tested at that point to see how well they did at it. The county had two other guys doing control work, but they didn't do a lot of denning, they snared and flew for the problem coyotes I denned but could only cover so much ground by myself, we all ground crewed for each other, the plane and helicopter. The county is 4265 square miles, so it takes a lot to cover it. So, if you have a guy flying and a couple of guys on the ground locating for them then the guys on the ground will take the dens while they are in that area and good dogs make that easier as well as faster. I took four dens in a day one time, 4 pups in one six in another, 8 in one and 10 in one for a total number of twenty-eight pups. but the guy in the plane got 9 adults off of those dens then went to another area and took more adults while the new guy who didn't areal gun took those dens. The guys on the ground crews give the plane GPS quadrats, you get there ahead of the plane sometimes locating the adults while it's still dark and take down the quadrants then move on to the next area. Often you locate call the plane or helicopter get them on the location and then haul butt to another area and locate more call them in and do it all over again making a mental note of each location that the coyotes answered at so you can go back pick up the aerial shot coyotes that are marked with ribbons by the plane then take the den. If the plane sees a den, they will mark it also with a ribbon It's kind of like the chaff a fighter jet uses to confuse radar only normally just one let go at a time. and these guys will get it right on top of the coyote I wouldn't want them dropping explosives at me or the gunners shooting at me. I ground crewed for a couple of them that could put two rounds in a running coyote on the same pass. My country is pretty open, and you can see for a long distance it has draws, hills and valleys, sage brush ect. but you can still see the coyotes once you have trained your eyes to know what you are looking for. Often the pilot and gunner will be looking for a moving target and it's hard for them to see a stationary coyote that blends well with the terrain. That's when the ground crewman gives them a mark and wing tip location as they pass over it. I got pretty good at seeing standing or lying coyotes and have shot them from the helicopter before the pilot saw them but would come to a hover. It was learned by calling and having them come set, stand or lay down not moving while others wouldn't see them. To my way of thinking a lot of coyotes are educated in that manner they just feel something is off or are on the edge of their territory, so they just observe and don't move then aren't seen, the caller gives up at that stand gets up leaves the coyote watches them leave then after a while goes over and low and behold smells human scent. Just my thoughts and what I have observed by being with others that didn't have themselves trained yet to see standing coyotes or other predators, what do you mean do you see that coyote or bobcat? Where is it? Type of thing.
