Well last fall I spent a good amount of time just outside of Mount Rainier national park in the Norse Peaks Wilderness searching for grouse. I made a few trips up to one particular area spanning from June to August, each time seeing at least one bird and hearing many of them 'hooting'. Come opening day and 40+ hours of hunting, did not find a single bird nor did I hear any hoot. This area was high elevation at the tree line and looked like fantastic habitat for blues, but like I said they disappeared. Am I missing something or was this just bad luck? The only thing I can think of that may have moved the birds is that there was a decent amount of foot traffic because there is a hiking trail that goes along the backside of the ridge. Other than that I can't understand why they would move. Any knowledge is great appreciated.
