They had a man fit security cameras on the front of the house, at the same time a new green bird box/feeder went up at the back.
It looks strange, isn't see through and has a large metal hole plate.
I haven't seen any birds on it and he has cats.
He also told me once how he hated birds.
If it is a camera it points at our bathroom window and has a view of my children getting into the bath. Its not an angle that a human could see. I have closed the curtains for now . I need to know 100 per cent if it is a camera before thinking about taking legal action.
