The different viewpoint shows the colours beautifully. Just a tad more depth of field would have got that beak really sharp, but a minor nit as the colours along the back are the main focal point.
I see a slight magenta cast on the image, like Simon I think f2.8 is just too shallow to get all the detail in, I take it you have a new camera too the exif say's 40D look forward to seeing more.
