Me And My Shadow ?

 Four goldfinches arrived together, but of course only two on the feeder.   Was trying to see where the others had gone, when I caught a glimpse of a different bird sharing the feeder, took a quick shot to check it out.  Then I realised it was just a trick of the light and the one at the back was definitely a goldfinch, as can be seen from the extra.  Not a wonderful shot, but it was taken so quickly before the light changed.
