One of the amazing things to witness when the Luneau video first came out was how quickly, equally experienced, skilled, reputable birders/ornithologists came to utterly divergent conclusions: i.e. the bird was clearly a normal Pileated Woodpecker in escape flight, or no, the bird was potentially/probably an IBWO, and certainly NOT a Pileated. Any cognitive scientist will tell you how weak human vision, and especially brief looks, is as a basis for firm conclusions… indeed, many a criminal trial has hinged on eyewitness testimony that later proved simply erroneous.
Anyway, there are thousands of great optical illusions, demonstrating the clear shortcomings of human vision. Here’s a big handful of some faves:

With all that said, nevertheless I've consistently long-felt that short of clearcut photographic/video evidence, the only IBWO evidence that's very persuasive to me are sightings claims (preferably not brief or distant) from experienced, knowledgeable observers (which remain few-and-far-between). As weak or distrustful as such claims can be, the other evidence proposed for IBWO presence is yet far weaker, reminiscent of Loch-Ness-Monster evidence (...though DNA evidence, if ever found, could be interesting).
It is especially devastating that despite millions of frames shot by automatic remote cameras (which have issues, but not the flaws/constraints of human observers) focused on cavities, foraging sites, and flyways not one single IBWO has been captured in years of effort. As others have suggested, perhaps Ivorybills actually reside in points A and C but we are only repeatedly looking in point B where they briefly traverse/disperse through on occasion… or, of course, perhaps they simply exist no more. The beat goes on….
(I have 4 or 5 more postings I'm considering between now and end of January, but after that it could be a slow year here at the blog.)
