Thanks glad you liked the pics.
I am certainly not disputing the statement that it could be oversharpened, I did way more than I normally would because it appeared to be taking it ok. That is why I need to learn how to really tell. I usually look for a change to the texture or a brightening in the feathers or a halo around the bird. I didn't notice any on these which is why I am asking what aspects lead you to the conclusion that it is oversharpened. I still don't see any halo even after you pointed them out. I will have to play with this photo some tonight at home and try to learn how to see these things you have pointed out.
Thanks for bringing it to my attention.
