This is an update collection of reports on both the pterodactyl and giant bats. There are actually comparatively few such reports, no least because there are few collectors either. Yet we have seen enough to satisfy ourselves that these and several other flying cryptids surely exist but are otherwise rare.
That means we rely on the lucky few who do see something then having the determination to share the observation with someone who will simply not dismiss them. Likely in these particular examples, there actually exist hundreds of legitimate sightings with the typical observer keeping his mouth shut.
We really need a better publicized data collection initiative that is judgement free. BFRO for twenty years has nicely policed bigfoot data to the point were we have several thousand excellent confirmed sightings. This makes dismissal downright silly and certainly ignorance run amok. We need the same type of support for giant bats and pterodactyls.
Do note that the importance of confirmation is to judge the observer by an independent investigator. Otherwise every report falls under the fear of the teenage boy playing the fool.
