DSCN3039.JPG: Was an easy and fast reject. Did you ever look at this picture at 100%? There is nothing in focus on that picture.
DSCN3018.JPG: Also not sharp. The bird shows no details (would probably not, even if sharp) as it is overexposed. Straighten the image (not that I think that with straitening and resubmitting you were done. The image is irrecoverable, but the bird should stand straight).
DSCN3048.JPG: washed out structures in the feathers.
Optical aberration between the bird and the background!
DSCN3047: washed out colours, over exposed. If the picture were more detailed (first point), you would probably need model releases.
