Appeared in my garden in West London UK
It's a pigeon. Shaped like a pigeon, behaves like one, associates with other feeding pigeons/doves.
But, it's black, with iridescence at back of neck/shoulders. Biggest pigeon/dove we've seen.Has a small ruff at back of neck. Holds tail high when on ground, with wings folded under tail. Nice orange eye surround.
Anyone help, please? Thanks in advance.
