i saw about 100 of these birds all on a grassy bank about 9 o'clock last night. same shape as a pigeon but slightly smaller. they were white with pale grey wings.
sorry, yes scotland in a town, Prudie. Dottie, they were very similar but no black markings on the tail. it was the amount of them that drew my attention at first, all pecking at the grass. Although it was dark there are a lot of overhead lights as it's a retail park.
