There is a strange noise coming from my wall.
This happens every day and generally starts after about 14.00. This happened last year also but stopped in the winter and started again a few months ago. There is no sign of any animals or anything else gaining access through the outside wall. If I bang the wall the noise doesn't stop or startle whatever is there so it is hard to tell what it is. I have tried to capture this in the attached files. Does anyone know what is making this noise ?
I want to make sure there isn't a protected species in there before proceeding with any further investigation

I've had squirrels come down inside the wall to around head height, but nothing like as low as that. Doesn't sound a squirrely sort of thing to do, going as low as that does it.
I've been wondering about your noise. I think the fact that it's so regular, that it doesn't stop when you knock, and you can't hear scratching or rustling, must add up to mean that it isn't a creature at all. I think it has to be noise from a water pipe or some other human thing like that. For sure it sounds like some sort of animal, but I just don't see that it can be.
I would tend to agree with you but the noise did stop when winter came and then started back up around April which wouldn’t have happened if it was a water pipe.
the noise can change also by getting faster or slower
