What Is That Squeaking Noise

I hear a squeaking A bird? An animal scratching paws or claws on glass? My light fixture cord is dancing I concentrate a bit harder. The noise is coming from the base of this light fixture It sound like a raccoon is in the attic twisting the bulb. It is making a hard rusty sound Screech screech screech The cord of this light fixture appears to be possessed Could It be bewitched? I listen and watch in disbelief, as the screeching continues Wishing it had been a bird
