Some birds are so hard headed that when they spot a window and see their reflection, they keep ramming into the window over and over again. They will only stop to land on their feet or their back, fly back around to the starting point, flap their wings, gain speed and ‘thwap’ smash full speed into the same window all over again. They continue this from dusk when light first finds its way until dawn when the light slowly fades the mirrored image from the same window.
