uncle nicky. that sounds like a very good possibility for a gobbling lull. i have seen it happen here many times but i never paid enough attention to remember if it coincided with leaf up.
the bird you mentioned may have been shot at before. or he might have just decided to leave those hens. who knows when it comes to these birds.
Phil. i am interested in knowing if this is just in your area or if it is the whole state. do you know people in other parts of maine and are the birds around them not gobbling as well?
