A species I havent seen before Dave. Excellent exposure, and this is really sharp. Apart from the vultures, GC was kind to you with the smaller guys too.
Overall very nice! I agree with toning down the perch, and I would crop from bottom just enough to hide the slim extention of the perch at right as I don't feel it adds to the image. Love the pose, and the clean and slightly mottled BG.
Thanks to all for looking and for comments/suggestions. Daniel I agree with cropping the perch.
The persh is a light coloured sandstone but I suppose the colour could be changed.
