Very interesting, sm4him. Nice shot of yours, as well.
I did got the bird sharp in other shots in this particilar sequence, but this one showed up intrigating and nice to me.
The focus was on bird (who was sitting in this branch), but as soon as it flew away, I got this image (70-200mm f/2.8 lens @ 200m, 1/250 sec, f/4.0, ISO 1250). This setting made the bird motion blur it away, and blend it with the background (with some extra help of the B&W colors), despite it was still inside the DoF area, right above the branch.
The confusion caused by the motion blur is what attracted my eyes. You can see its legs moving out of the branch, if you pay attention to it.
However, a 1/500 or 1/750 shutter speed could have resulted less blured and closer to what you describe. Anyhow, I kind of liked the end result, of course, that's why I'm bringing it here.
Thanks again, very much!!
