Yoga for Geese

I think this one is Warrior Pose 3, or Virabhadrasana III (I'm fairly sure someone will be along shortly to correct me). 

Who knew Orinoco Geese did yoga?! The others don't seem awfully enthused, and as someone who has been bent about by experts I share their nervousness... I'm ok with toe pose and even down dog, and I can sometimes manage tree pose (if you imagine the tree is subject to considerable gusts of wind) but I suspect geese have additional qualities of balance.
