I enjoy hearing the bugling and hearing them grazing behind the camera.
One time I even seen a elk as the camera was panning towards how ever it senses to pan and move to get critters in view.
There were a dozen turkeys in view for some time before sunset.
I let it run in the background and tweak the volume in the player it is on. Enjoy
