Peregrine Falcon in B&W

I really like the colors in the Peregrine Falcon, but I thought I would try today shooting in monochrome:

ISO 160 50mm f/3.5 1/10

This was taken with a 50mm lens, but isn’t as tack sharp as I would have wanted it to be.  It is a little fuzzy at the tip of the beak, something I missed when I previewed it in my camera.  I will put the original photo below, but the one above has been edited in GIMP.  I cropped, changed the levels, added some contrast and sharpened it. There is a bit of detail lost in the tail, perhaps a flash would have helped with that?

I welcome all constructive comments!

Cheers!
