Spotted in my garden (suburban, neighbouring farmland, mostly dairy). Eating from my bird table along with finches, tits and robins. Feathers are bright white with black patches on the wings and brown patches on the breast. Bill and legs are yellowish. Bird is quite tame, allowing me to move this close to take photo through window.
Any ideas?
