Okay so it seems there were a few folks who thought that brown fleshy bit hanging down ...the one by the side of his face...was some sort of rubbery earring.
I looked at some pictures of the other Huaorani and it seems only a few use the ontoka (a wooden disk). I saw no one wearing them when I visited in the mid 1990’s so I wondered if they were only used on heydays and holidays.
I found a description of how the piercing is done by another author who visited with the Huaorani and holds them in high regard as do I. I have written for permission to post it.
Suffice it to say for now that it seems that the Huao prefer the pierced lobes to swing empty.
At any rate here is my updated version of the Warrior
