Bill, could you elaborate on how dense the branches have to be to encourage YP to use them?
i.e. 1"-2" diameter branches from the top of an Oak Tree vs. tops of a River Birch Tree that are down to 1/8" diameter and relatively dense?
Will the YP use the branches if the individual tree branches are a foot to 3 feet apart, or will they be more attracted to branches that are more closely together like branches from a bush?
