There was one bad experience during my visit in Michigan. Julie had taken their dog to the vet while Abigail was taking her afternoon nap, and I sat quietly reading in the living room. All of a sudden, there was a HUGE BANG and this glass window, which I sat facing, SHATTERED!!!! Can you say "heart stopping"?
I jumped up, ran over to look outside, and this is what I saw. A grouse had flown into the window! Unfortunately, it lay dying of a broken neck as I reached the window.
A few small pieces of glass had fallen to the ground, but most of the shattered window had fallen into the space between the interior glass and the storm window.
I don't remember ever seeing a grouse up close, or for that matter, from a distance either. I have no idea as to why it had been startled and flown into the window. Perhaps it saw its own reflection as an intruder and was flying at it to chase it away? We'll never know.......
