Geting a bird to come to you right off roost is tough. Especially when competing with hens. I like to call very little getting an answere or two and staying quiet till they are on the ground. Sometimes it wont be the bird you are calling to that comes in. It will be a silent bird you might not have known was in the area. I have had this happen on more than one occasion right off roost. It is the most exciting time to be in the woods but it can be the most frustrating.
