Yes. I think KK has enhanced the contrast and sharpened the image in post-production - something most (all?) digital photographers do to make the image more strikingly effective.
Nothing wrong with that, but it can sometimes have the effect of exaggerating certain features with the result that the birds may not appear quite as they would in the field through binoculars or a scope. So I'm not sure that the rumps of Gt Knot normally appear so strikingly white as they do in the photo; the same with the contrastingly dark primaries and primary coverts.
