Regardless of what some critics say about the concept of modern living pterosaurs, the hypothesis of Marfa Lights being from those cryptids is not soon flying away. Of course, not all nocturnal predators flying overhead need be living pterosaurs. Owls appear to be much more common, although acceptance of the hypothesis of barn owl bioluminescence is hardly common among biologists (it is explained in the book by Fred Silcock: The Min Min Light). The strange flying predators thought to cause Marfa Lights—those creatures act more intelligently, at least sometimes, than barn owls, and that supports the more-revolutionary hypothesis of nocturnal bioluminescent pterosaurs.
The point about owls is that they are dull-minded, at least they seem to be specialized for individual hunting techniques rather than complex group behavior. Two barn owls often hunt together, of course; but do the two hunt in a truly coordinated manner, like whales that encircle schools of fish with bubbles? I doubt it. But the intelligence of ropen-like flying predators—that is a possibility, more likely even than highly intelligent barn owls.
Of course, the strange flying lights could be from multiple sources: owls and ropens. But the problem with that idea is simple: If large ropens fly over Texas at night, glowing barn owls might not live long glowing.
