My sister lives in Connecticut and has been observing some strange behaviour over the past couple of weeks from a male house finch. It keeps flying into the window with its feet and then hits its wings against the window. There are orange/red droppings all over her front porch. She has tried to discourage this behaviour by putting up objects in the window but there has been no change. She is concerned that the bird is hurting himself. Does anyone know why this is happening and have any suggestions?
