Back to comment: Sorry to say but this image looks more like a snapshot from the zoo that you thought might fit the challenge than it does a portrait. This image would be easier to accept as a portrait of a bird if it were more closely cropped. The partial birds at the top of the image are a big distraction and add nothing of value to the picture. I would suggest playing around in post processing a bit more with this image, as the detail in the bird's face are pretty much lost.
I have a feeling that you might get creamed here because it's not what people consider thinking of a classic portrait. Good colour. I'd have liked slight more sharpness on the bird's head for a couple more points.
