I didn't make it over to Franz Josef, but I hope to on a future trip! Agreed on the kea too, very cool. When they were hopping around near us, I picked up on an awareness from them on the level of a dog or cat at home. They were very with it. Although a five year old, I don't think even my cat and dog are that smart!

Thats what i found about them and what the guide told us. We did the ice climbing trip and they were hopping around us, curious as to what we were doing
