I was holding my son up looking out our living room window this morning and THWACK a medium-size bird hit it. Startled us both, poor bird didn't survive.
I wonder how much help non-vertical glazing would be. Maybe windows inclined 10 degrees down to reflect less of the sky? I wonder how many birds total live in the US. 600 million is a lot to lose, but there still seem to be plenty birds.
