What is this sound?
theres probably birds or squirrels doing that
it could be a couple of branches rubbing together. It could be wires rubbing against something, it could be loose rain gutter rubbing against the house in a breeze. We have an odd sound in our neighborhood like that. its from 2 close growing trees across the street from our house..any day its kind of windy you can hear it quite well.
Maybe a swing?

Rats in the walls?
