This was the best shot of the morning, and I like that you can see the various shades of brown in the bird. When I put it up to 200% magnification, it holds up pretty well in terms of clarity with the exception of the tail feathers.
This shot was taken using a 50mm lens. It was also handheld because I forgot my tripod (umm, hello!) it was a bit early, but still. I do usually pack up my camera gear the night before, for exactly this reason.
From the comments in the original post I have one more way that I am going to approach this bird. Thanks to all who left their thoughts! So far this flash version is my favorite, but what do you think?
