Please don't paste what the solution of the image is in the comments. It totally ruins the surprise of seeing it appear. If the author wanted you to know it was a hummingbird, they would have called the piece 'hummingbird'.
Thank you Markblonde well said - sadly there are a number of players who want the world to know they 'got it' - as if anyone cares. I try to be charitable and tell myself they can't help their need to parade their success at solving a puzzle and that their habit for destroying the surprise for others is not based on pure malice.
