I find although sometimes I can get closer I have to back away to reduce the possibility of the bird flying out of the frame, thus more cropping.
Well caught, Jack. I would be tempted to use a sightly smaller aperture to give more DOF and thus leeway with the bird moving from the point of focus acquisition. I agree with Fabs suggestion to crop from above and I would smooth out the light and dark streak in the bottom left corner
