For the life of me I can't see how this 'thing' in the video could be mistaken for a Sandhill Crane. I just don't see it.
And, if you watch how a Sandhill Crane moves - their legs joints do not bend like the 'thing' in the video.
Sandhill Cranes 'knees' (if they are knees) work more like elbows kicking out backwards as the bird moves forward.
Whatever the 'thing' is in the video? I've no idea, but, my vote does not go for the Sandhill Crane.
Thanks for an interesting post. Interesting as in the excerpts from the original video.
The show, IMO, is just too 'woop-woop'...
