Columba livia, or the common pigeon.
I imagine this is not the usual angle people are used to seeing pigeons; rather, you probably picture them from above, staring up at you from sidewalk level, begging for a piece of whatever it is your eating, in the dingy second-hand light found at the concrete bottom of your urban canyon.
In this light their iridescent neck feathers are quite striking.
Canon R10, f/14, 1/640sec, ISO-500, the full 400mm using the Bird Lens.
