Bird deterrent

I put these on our windows a couple of months ago. They are designed to stop birds from flying into the glass. I thought they were working quite well until I spotted signs that a pigeon had tried to fly through the space in between the stickers. I’ve since moved them to narrow the gaps, so hopefully we’ll have no more crashing birds.
In other news - Mr H is recovering well. He’s finished his antibiotics but is still on painkillers.
