Oh that's maddening! Where is it? Can you see it?
At my parent's home (I was grown and married at the time), a cardinal kept attacking one of the windows with a vengeance--crash, fall to the ground (it must have seen its reflection as another bird). That went on for a few months until my dad thought to put up dark screening over the window.
A friend of mine was tormented by a woodpecker constantly fruitlessly pecking at the gutter of her house. They moved (they were moving anyway lol).
An old neighbor shot and killed a woodpecker that wouldn't stop pecking on their tree (not that I recommend that).
These were rather deranged birds. Obsessed, addicted (hope that brings a laugh).
I hope there can be a solution to this problem for you. Maybe it has a nest somewhere.
