I started clicking them together, and it sounded surprisingly like a grouse’s clucks. Almost instantly, I heard a rooster nearby set off in a flurry of clucking that resembled an angry turkey more than a pint sized fool hen. I kept up the charade, clicking the rocks in the same pattern that the grouse was blasting, working a little closer to where he was. When I saw him, he was about 30 yards away, up in a spruce tree. I just kept on calling, and he couldn’t take it. He flew to a closer tree, then one even closer. I was already in disbelief, but then the rooster dropped to the ground about 10 yards in front of me and began strutting.
