It can be quite difficult to sort out Stock Doves from Feral Pigeons, less so Woodpigeons. They are smaller than Woodpigeons and lack the white patches around the back of the neck. They are an overall blue grey colour with green iridescent band at the back of the neck and pinkish breast. They have two partial black bands at the back of the wings. You can separate from a Feral Pigeon by the lack of a pale rump.
