I have called in and shot coyotes in the west, mid-west and southeast and I found that they are much more difficult to call in the southeast. There is so much cover, weeds, creek bottome, ditches, ravines and woods that they can be on you in a heartbeat. It is also hard to cover downwind. When I hunted them out west and in the midwest I could call in and shoot several in a day. Here in the souteast I feel lucky to actually kill one every 3rd time out. With all the cover they never really have to cross much open ground to circle downwind. I have had the most success in setting up where I had some kind of natural barrier on my downwind side. When I can I will set up with a cliff behind me or a wide / deep creek. It helps funnel them to you on the upwind side and hopefully across an open field. I have had the most action here when using a combination of sounds at the same time. The last two I shot have came to a conntontail in distress call and a woodpecker in distress call playing over the top of the rabbit sound. The newer electronic calls will play 2 sounds at the same time. I would think that your terrain in sw Virginia is very similar to my Tennessee terrain with fields and pastures broken by rolling to steep hills, creek bottoms and timber stands. I am going to go out this evening and tomorrow morning. I hope to have some success as the breeding season is now upon us.
