Sorry, can't help you with the ID here, but man I love the radiant BG!! There is just a small patch near the wing-tip and tail that looks like it was touched up. I also feel the bird a little tight in the frame. Lastly, I would lighten the eye a bit (but NOT the pupil), and the area around it. I like the "wet" look. Was it raining, or was it visiting a bird bath?
Sharpness and light look good but the BG makes this one for me. I might give it a bit more room and can't help with the ID, either. I only wish for a bit more eye contact.
