I've recently been granted access to a new piece of ground. The landowner says that he sees turkeys regularly. I hunted this property yesterday morning, and did not hear a single gobble on roost. I am used to hunting large river bottoms, where gobbling on the limb is just about guaranteed. My question is, does this lack of gobbling mean that the property is largely void of birds, or just that they do not use this or the surrounding farms as regular roosting?
