Pigeons are thick...

Didn't know about the dust thing until I saw the picture below and seen a couple since...

I've had some great ones. I used to live in a south facing garden with a pain of glass about 3mx2m. The birds coming out of the woods at the bottom of garden always became dazzled in the reflection of the sun regularly hit the window.

The downside was that the neighbours cat cottoned on to this, and used to sit and wait... Having a toddler come running in to the kitchen swinging a headless pigeon with its guts ripped open wasnt something the wife enjoyed.

Scared the tulip out of me and the cat!

The cat is not scared. It is just rueing a missed opportunity.

To be fair there are more than enough videos on YouTube of people walking in to glass.

I never had a bird hitting my window, but I did have this nosey parker one night
