That bird looks outright pompous! And that view makes me want to say, GET AWAY FROM THE LEDGE! Nice how you got the Empire State Building in the background.
unfortunately the cloudy/overcast day transforms right through your photo, the focus is not sharp around the pigeon's head and the colors just don;t jump out at me
Nice composition. The photo seems to be a bit hazy and blurry. The bird doesn't seem to be in focus, especialy its head. I think that if you had croped a little more out of the bottom of the photo it would help.
