Noise disturbance caused by birds on the chimney

I don't understand the idea with the chicken wire. They just sit on it anyway? Spikes would be best.

Hello Tassimat You are absolutely right. This pigeon deterrent is necessary. But you cannot attach it to the existing cover. Gluing works but doesn't last long. So they go on the cage. Steven

There is no better surface than metal to attach the pigeon spikes with rivets!

Hello Alessandro

would you drive blind rivets through there?
And in a short time, the rust would have enlarged the holes.

Steven

Don't shout like that!

That could also be that they attack their reflection.
