I think the B&W conversion shows a very nice tonal range, excellent detail. Very difficult image to capture from a dof standpoint with three birds, one landing.
I would have considered trading a bit of shutter speed, go to perhaps 1/2500s to get a little more DOF.
The clipped wing doesn't bother me, as all the lines lead to the center of the frame.
In a perfect world, would hope for slightly more separation of the heads of the top two birds.
This is a pretty powerful image, and I like the conversion. Super tonal range and a lot to look at and consider. While I like this composition, I find the clipped wing a little too bit in the frame and taking some of my attention away from the action...not b/c it's clipped BTW. I tried a version cropped down to the cut in the wing feather and a little more off of the right as another option.
