As I type this there is a female bluebird attacking one of my living room windows. She goes from sitting on top of a suet feeder, about a foot away from the window, hits the window and goes back to the suet feeder. She does this over and over. It sounds like she is hitting the window with her head. Last year she did the same thing to a window on my storage building. She has also done it to a window on my truck. I first thought she wanted inside the storage building so I opened the door but she didn't want to go inside. Since she is now attacking my living room window,I feel like she is trying to tell me something but I don't know what. She seems very frustrated. This goes on for months. Any ideas?
You need to cover the window so she can't see her own reflection. She thinks it's another bird and she is trying to attack it. Very common behavior, cover the windows.
