This image was too tight on the bottom, so I added a little. The eye is not as sharp as the portrait I posted a few days ago, but the action and early low light prevented me from achieving more. I did not go higher in ISO. Shot a year ago.

Great image Steve of the wing action while maintaining sharp focus on head and body. Composition would be greatly improved by a bit of space in front of bird, and agree with Axel that the whites are borderline.
