I have a pet iguana that I keep in a cage on the other side of a room from the window. Over the past week a male cardinal has repeated flown to the window and has tapped at it with his beak, while his mate sits on a branch behind him. My iguana just sits and looks at the cardinal with an expression of, "what is up with that stange bird?" I am curious to find an answer to the same question. What is causing this behavior? Will you please help me and answer my question?
