Poor birdy

Speaking of birds, we have a large, five pane, bay window that faces our backyard and a sort of greenbelt area. This morning there was a very loud "bang" and I knew that some poor bird had flown into the window glass, which wouldn't be the first time. What was a first was the little ring of white feathers sticking to the glass from the poor thing's impact. I looked and didn't see any birds on the ground, much to the cat's disappointment, so hopefully it will be okay.
