Have you any advice about getting rid of pigeons?? We feed our birds regularly, have lots of different species coming so put out different kinds of food, but we are now inundated with pigeons, who assemble on the roof – my husband counted 34 of them one day – and swoop down to eat, No matter how many times we clap/ stamp/bang doors etc. they come back within minutes. Any ideas? We do not want to stop feeding birds!
