One for the bird experts. I had in my garden tonight what appeared to be a black Magpie. Other than it's tail feathers, which were standard Magpie blue, there wasn't a single speck of white on it. It had the same shape, size, and walk of a Magpie but was black from head to toe. Any ideas as to what it was? I know they are a member of the crow family but it definitely wasn't a crow.
