How do you attract a whippoorwill bird?

We had one right below our bedroom window. When the birds are close, they are EXTREMELY loud. Tried a plastic garden owl. That worked for one night until the bird figured out it was plastic. Tried a trap. The bird didn't go near it. Tried sprinkling used cat litter around, thinking the bird would detect a natural predator. Nothing worked until I put out a string of white Christmas lights on the ground where it normally sat and screeched. I feared this would just attract bugs and provide a buffet for the bird, but so far, so good. It has kept him away for the last week. Keeping my fingers crossed.
