This was a tough shot to get!  It was very high up in the trees, and very difficult to even get it in my viewfinder, dealing with the movements of the boat, etc.  The EXIF data shows this to have been over 320 feet away!!  In fact, it was hard for us to tell what species it was at that distance, but we were thinking Peregrine Falcon.  This shot is a fairly extreme crop from the original frame, and the Mark IV's extra pixels definitely came in handy here.
