I shot my daily pictures early in the morning. While I was shooting pictures in my back yard, I heard birds singing behind me. I looked at the bird feeder. No birds! I then looked up and saw the sparrows on my house's roof top. I snapped this picture just at the right time to capture one playing "king of the mountain" by sitting on top of the hot water vent stack. Some of the other birds in the flock can be seen behind "him".
