Roger Knoll submitted this image taken with a Nikon D300, with an exposure of 1/160sec at f/6.3, ISO 400. A wider crop that includes the end of the tail feathers of the closest birds would improve this photo greatly. Consider trying a horizontal crop or a square crop to do this and to make the most of the horizontal lines of the birds. Using a smaller aperture also would have kept the two front birds in focus instead of just the second one, then let the depth of field fall off as the viewer’s eye moves through the photo. This appears to be a result of the center focus point, next time you find yourself in a situation like this try locking in the focus and then recompose the image.
