I have tried calling. I meanwhile have a $400 Foxpro Hellfire, but all for nought. For whatever reason I have never seen a coyote when using a call. It is as if they run in the opposite direction when you turn on the call. But if I move in before dawn and sit still, I see them moving through the area.
I have spent so many hours in the field, perhaps it is just a fact that one never seems to hear distress cries at all, and so when someone actually uses one it is out of place ? To give you an idea, I have been out on this property hunting since about the 3rd week of September so that is about 17 weekends (34 days) and I also spent 2 weeks of vacation in Nov and Dec full time hunting so basically over 40 days in the field. During all of that time, I never heard a single distress cry. Crows, yes. Birds of prey, yes. But no rabbits, voles or other squeaking critters.
I recently attended a forum at a local hunting club. The speaker was the foremost Michigan coyote hunter who goes by the name "Dogbreath". His basic tips were as follows:
1) In the eastern part of the US, coyotes have learned that cover = safety. So they are going to be reluctant to leave cover. This you can't expect to get them to come out the woods into an open field (there is problem #1 with my setup)
2) Predators use scent because their life depends on it. So if you are sitting somewhere with the wind straight in your face, it is VERY unlikely that a coyote will come in from that direction. That is because coyotes do not want to approach anything from upwind. So a better situation is to have the wind coming from the left or right, in such a setup it is possible that a coyote will come at you since they are not moving downwind.
3) Everything you do to get into your position needs to avoid contaminating any area the coyote may move through with footprints or scent. Coyotes will tend to take the path of least resistance, provided there is cover.
Those were the main things. If you can use height to your advantage (tree stands or whatever) it all helps getting your scent off the ground and improving your own vision so long as you are not skylined. More height would help in my setup too, as would clearing the brush out of the fencerows so that one can see what is going on in neighboring fields. In spring I am looking to hire a dozer for a day to tear out some brush that is virtually impenetrable.
