Birdbrain

There's a small bird, maybe it's a finch, that keeps flying into the bathroom window. Every morning for the past week, it hurls itself into the glass, sometimes hopping up from the windowsill and sometimes getting a flying start from across the yard. BAM! It only does this in the morning, when the sun is shining directly into that east-facing window. You would think it would be dead or at least have a horrible headache by now.
