Squab-proofing the kitchen window.
For the past two years, juvenile pigeons have died flying into this window. I've tried those bird shaped stickers which are supposed to help, but they're not very visible, and didn't work.
After some internet research, I'm hoping white vertical stripes will do the trick.
This is automotive pinstripe tape, but maybe a paint pen would be easier to apply.
Edit: does this qualify as #
Fensterfreitag ?
