Tales of pterosaurs are one thing; photos and videos of Frigate birds are another. The confusion between the two has become common enough to elicit a response here, for there is little actual resemblance. I now list web pages that are enlightening in this regard.
How Absurd! A Frigate Bird!
… the beginning of that video shows an obvious Frigate Bird soaring as Frigate Birds will soar. I’ve lost count of how many times I have responded to that video footage, explaining that it does not show any ropen but only a common ocean-going bird.
I realize that some believers in ropens know little or nothing about Frigate birds. Please note that when something is soaring, in daylight, over a beach or school of fish, and the wings resemble the wings of a Frigate bird, then we need to consider it a Frigate bird, unless there is something noteworthy that makes it differ from ANY kind of Frigate bird.
One video is so obvious that it brings up a question: “Why did the person who put up the video not realize the obvious?” The bird has the white throat-chest common for some Frigate Birds and it has the wing-shape of a Frigate Bird.
