The Red Bird

We have had a cardinal living in our backyard for a couple of years now. It constantly is pecking at our window like it is trying to come inside. Yes, this happens at 6am when we are trying to sleep. We have tried putting out an owl and also lining the window with foil(I read about both online) and nothing seems to stop this bird. James is very entertained by the bird and loves to stare out the window at it. If anyone has suggestions on how to get rid of this annoying red bird please let me know!
