Blk Footed Ferret pop-up

I am processing some images from last winter. One of my highlights was spending time photographing a black footed ferret, an animal that was declared extinct in 1979. A few years later a remnant colony was discovered and re-introductory efforts have successfully established small but sustaining populations in several western states. This is in Wind Cave National Park, SD. I was thrilled because the ferrets are primarily nocturnal and are seldom seen or photographed outside captive facilities or under artificial lighting situations. This one is wild, free ranging and apparently thriving. Check my gallery for a full body view.

D3S, 200-400 + 1.4 TC, 550 mm, iso 1400, 1/500, f9, +1.3 ev This is a fairly strong crop, with sharpness and contrast tweaks to maintain detail lost to the crop and from using the teleconverter. Your suggestions and comments are welcomed.
