That’s a good question, yes. I approach it from different sides, rather than just with one question, “Are modern pterosaurs bioluminescent?”.
Are any Large Flying Creatures Bioluminescent?
In other words, does anything larger than a firefly have wings for flying and have glowing capacity? There is a species other than a pterosaur that is purported to have intrinsic bioluminescent capability, namely the common barn owl, Tyto Alba.
Of course not all Barn Owls glow, but the Australia researcher Fred Silcock has written a book on this subject and he has some explanations. With one expert firmly believing that some barn owls in the wild can use bioluminescence, it may not seem quite so revolutionary to suggest that capacity in some pterosaurs. The name of the book by Silcock is The Min Min Light, The Visitor Who Never Arrives. This subject of glowing owls can get rather tedious, so I will move on.
Ropen of Papua New Guinea
I suggest, to anyone who would attempt to explain pterosaur bioluminescence to a skeptic, that we begin with reports of large flying creatures known to some of the natives of Papua New Guinea, creatures that glow as they fly. They are called by a variety of names:
The variety of native cultures in which this glowing flying creature is known is evidence of the biological reality of it, but not proof of its existence. But the following makes a substantial supplement to the native traditions and stories of encounters:
- David Woetzel’s sighting on Umboi Island in 2004
- Paul Nation’s video recording in 2006
- The Destination Truth video recording in 2007
We could easily doubt one or the other, doubting native stories of encounters with giant featherless flying creatures and strange flying lights or doubting American explorers who witness and videotape strange flying lights. But we cannot nearly as easily throw away both of them together.
We could doubt Gideon Koro when he testified that he saw the ropen that had no feathers but a tail “seven meters” long or we could doubt Duane Hodgkinson when he testified that he saw a pterodactyl with a tail “at least” ten or fifteen feet long. But we cannot nearly as easily throw away both sightings together.
In conclusion, the fact that we do not yet have a live or fresh-dead body of a Rhamphorhynchoid pterosaur does not mean we do not have a strong case for the existence of a modern bioluminescent pterosaur. Patience is a virtue, but I will not sit around and say nothing until someone gets hold of a body. I encourage everybody to be open minded and do what can be done to support the research and the efforts of those who get out and look for modern pterosaurs.
Bunnell’s H-4 requires two questionable things to interact. The bioluminescent-nocturnal-flying-predators hypothesis, “BNFP,” involves a questionable element, flying creatures not classified in biology, and an unquestionable element, prey such as bats, snakes, mice, and other small living things in southwest Texas. Of course, a predator need not always be hunting. They sometimes mate and compete for mates. Some predators even play. To the best of my knowledge, these aspects of group-predator behaviors can account for all the CE-III lights and more. The simplicity award goes to BNFP.
I have seen them, they look like bats but flap their wings way different than birds do… And they have a red-orange bioluminiscent [sic] body… First time I spotted one was somewhere on Nov, 2011; last time I saw 2 of them together a week ago [March, 2012].
The men soon realized that it was no bird that started to circle the clearing. It had a tail “at least ten to fifteen feet long,” (book Searching for Ropens, 2007) and a long appendage at the back of its head: apparently, a live pterosaur.
