The bloody pigeons, having been unaware of my garden for the past 4 years have suddenly discovered a feast of brassicas and completely stripped all my kale, Brussels and Perennial kale as well as leaving huge amounts of large bird poos everywhere.
I also have many small birds, like various tits, wrens, dunnocks, robins etc which I love to watch, harm no plants and actually perform helpful pest control activities while going about their business.
I know I can (and will) make and place nets or cloches over the brassicas, but I'd quite like the discourage the pigeons visits completely. But I don't want to scare off the small birds.
I've thought of shiny stuff hanging about the place, replica birds of prey, scarecrow but I think all of these would scare off all the birds (or fail completely).
Is there a way to selectively scare away the pigeons?
