    This is an ordinary blackbird which has developed abnormal plumage. A look at the close up indicates that it probably a male. Bill is yellow and the plumage in the central back looks black. The rest is a mixture of leucistic (yellowish) feathers and white. These are formed when there is a biochemical block or blocks in the pigment formation in the feather.
    The British Trust for Ornithology are interested in aberrant plumage and have a survey underway. you should fill in a form on their website:
