Attached is a comparison of some images from the recent Cornell website defending the identification of Luneau's video as IBWO. First is the image they themselves posted on the website to show how "unlike" the underwing patterns of the Luneau bird and confirmed Pileated are. Note the extensive black on the trailing edges of the PIWO wing. Also note that they are all flying in an angle perpendicular to the viewer, whereas the Luneau bird is flying directly away.(Click to enlarge)
Below the black stripe, I have added comparisons of some screencaptures of frames from the videos posted by Cornell of confirmed PIWOs flying away from the viewer. Somehow, the video analyst wizzes at Cornell seem to have overlooked that these images are much more like those in the Luneau video in the direction of flight... and, amazingly, they are also more similar in overall pattern! Huh. Well, nevermind, if you just overlook that minor detail, you'll see why Luneau's bird is still clearly so different from a PIWO. Right?
