Kanacki, you broght up a fascinating factor - cryptozology - that has many unanswered questions down here, for example the 'Carbuco'. This is a small bird, perhaps the size of an Owl that seems to have a light emitting organ in it's forhead - equal to a one cell flashlight - .
I was introduced to this bird (?) by my father in law. One day, while eating breakfast, he casually mentioned that a pair of them had ben living in a near by hill, l cerro de Pericos - hlll of the little parrots . He said that they were heavy flyers, that they seemed to fly in one direcion, and would turn on this light feature just before landing. But, unfortunately, they had moved on. So much for my investigating them, so I put it down to a local superstition.
Later when I was living with the Yaqui, they repeated the same story. They said that there was a small colony of them that lived in burrows on a sandy hill. I put off visiting them for fear of disturbing them (?) then suddenly they were gone, sigh.
Later a Priest near Guasave notified me that he had the body of one that an Indian had brought him, and described something the size of a large owl with a third 'eye', and invited me to visit him, but before I could, he died. All traces of the creature disappeared
All stories of the creature indicate something that flies like a grouse, and has something like a third eye, that is capable of emitting light, for what purpose I have no idea.
This is just one example, I have several. For instance that giant aquatic serpent that I found myself swimming with while on the Gloria Pan hunt, that little, very venemous snake, the 'Pichi Quate',the size of a lead pencil, the large bird of prey that would swoop down and catch Yaqui Children, and on.
One thing that occurs to me Kanacki, during ww ii, The Japanese were heavily into those Islands, have you ever found any report of them ? I do recall a science fiction motion picture of a lost aircraft crashing unto an unknown island and finding the Japanese garrisoned there living in terror of them, that must have been based upon the Ropen (Pterodactyl) rumor.
I can't even go to Mexico until (at best) next year, and that will require some luck. Besides, Don Jose' has already found Tayopa, now it is just a matter of digging the goodies up. Unfortunately finding a lost mine (or a whole group) does not automatically translate into wealth, but I think Real de Tayopa is not going to keep us waiting much longer to see that treasure, in fact I think he is very close right now.
