The mechanics of the shot are well controlled. The shutter and aperture are well selected. The image is quite sharp and the colors are very good.

One major problem is the fact that the bird is lit from the back and that puts a lot of the interesting details (especially the eye) are somewhat obscured by the shadows. We can't always control for such factors, but remember, that in avian photography the eye is generally the most important item.

The worst picture is the one you don't take because of less than perfect conditions.

Well done and keep shooting!
