The banging on windows and doors has subsided for now. Yes we have a nest at front of house where a downspout meets the brick wall. This nest has been there for 5 years, it just keeps getting re used.
I Think There are too many Robins looking for territory down here. Up at our House in Tiny we have a similar nest at the front of our Carport that keeps being re used but we have far fewer Robins about and there is no window banging.
We had an issue a few years back where a Northern Flicker was making a god awful noise on the neighbours stainless chimney.
Oh! and Axeman yes, Robins are nesting even up at the beach. There is one at the nest at all times.
