-- Holiday Note --
------------------------------------------------------------------
-- HAPPY HOLIDAYS to all! -- |
Whenever the world seems to trample on hope... we still return to it . . . .
Lyrics:
We believe in things that we cannot see
Why shouldn't we, why shouldn't we
Hands that heal can set a chained man free
Why shouldn't we, why shouldn't we
We believe in peace within every heart
Why shouldn't we, why shouldn't we
Burning brightly, brightly in the dark
Why shouldn't we, why shouldn't we
So come on darling feel your spirits rise
Come on children open up your eyes
God is all around
Buddha's at the gate
Allah hears your prayers
It's not too late
And we believe in things that will give us hope
Why shouldn't we, why shouldn't we
Let your voice be heard, celebrate your vote
Why shouldn't we, why shouldn't we
We believe in things that make us all the same
Why shouldn't we, why shouldn't we
Love belongs to all in deed and name
Why shouldn't we, why shouldn't we
And we believe in things that can't be done
Why shouldn't we, why shouldn't we
Lift up your heart, put down your gun
Why shouldn't we, why shouldn't we
We believe in things
We're told that we cannot change
Why shouldn't we
We had heroes once, and we will again
Why shouldn't we
So come on darling
Come on children
God is all around, Buddha's at the gate
Allah hears our prayers
It's not too late
Why shouldn't we
Why shouldn't we
Why shouldn't we
Why shouldn't we
Why shouldn't we

-- Thought I'd Read It All... --
------------------------------------------------------------------
Thought I'd read all the old Ivory-bill stories, but this one from the Texas Big Thicket crossed my screen, and I don't recall it (IBWO part in second half of story):
http://venturegalleries.com/blog/strange-creatures-really-live-thicket/
Upon first reading, I figured it was some sort of fictionalized account or creative natural-history writing, but upon researching it, turns out to be a true story from 1967.
This old volume (among other places) on the Big Thicket references it:
http://tinyurl.com/ktw4b42
The fellow took his specimen back home with him, and there was no serious follow-up or further indication of IBWO on his property, so I can't tell if there's any validity at all to the almost 50-year-old tale... it sounds a bit fishy, if only because it rings so much like a fabricated knock-off of the much-earlier Mason Spencer story from Louisiana (which of course is true)... nonetheless, entertaining.

-- Mike C. Back at Pearl River (last month) --
------------------------------------------------------------------
Mike Collins keeps re-posting various past videos at YouTube (perhaps to keep them appearing as 'recent' in the search criteria, or maybe he adds new commentary or footage, I'm not sure since I don't have time to check them all), but he's also added some fresh footage from his latest Pearl visit, two of which I include below. Nothing new, Ivory-bill-wise, but I did enjoy this first, almost meditative, 15-min. clip from one of his rigged treetops. Almost no commentary in it, and not much action to be seen, just a nice, tranquil canopy-view of the Pearl area in late fall.
Don't know if he has new equipment or is simply more-practiced by now, but I was impressed with the film-quality and his ability to quickly maneuver/focus the camera in that tree'ed-position. Given that I now believe IBWOs may spend 80+% of their time at canopy-level, of course this tree-top view, and the panorama it provides, is all the more interesting (though it also means the viewer is locked in place, and with but one set of eyes, is missing much of that panorama at any given point in time). Will still take a great deal of LUCK to chance upon a clearly-photographable IBWO from that position. Anyway, this might bore most readers, but I enjoyed it:
The other (also 15-min.) video is from ground-level in a kayak, demonstrating Mike's "paddlecam" (camera attached to a kayak oar); more wildlife action here, and much commentary from Mike, so may be the more interesting clip to most people, though I preferred the first (and again, even with videocam attached to paddle and moving kayak, film quality surprisingly good):

-- Congrats Geoff!! --
------------------------------------------------------------------
A quick side-note today, as I just learned that Geoff Hill, known in ornithology circles for various areas of research, but familiar to most of us for leading the Choctawhatchee-area search for the Ivory-billed Woodpecker in the Florida Panhandle, has been awarded the 2014 William Brewster Memorial Award of the American Ornithologists’ Union -- quite a lifetime honor! Way to go Geoff!
http://www.oanow.com/news/auburn/article_d5c7eb32-60b7-11e4-8422-001a4bcf6878.html
Interestingly, by the way, last year's recipient was J. Van Remsen of LSU, who also has a large body of research work, but is likewise especially well-known for past efforts within the Ivory-bill search arena.

Don't know when (if) there will be any major IBWO news to come along, but for now will simply refer readers here to the two ongoing searches already linked to:
Project Coyote has put up several new postings in last couple of months: http://projectcoyoteibwo.com/
Additionally, they also have a Facebook page here:

http://www.ibwos.blogspot.com/
Those appear to be the only ongoing searches with a Web presence. I continue to hear from brief forays into traditional IBWO search areas, but of course those have tailed off considerably by now, and are turning up nothing I've heard of.
Meanwhile, indefatigable Mike Collins has put up yet another YouTube recounting of his first 2006 video encounter with the big woodpecker (as best I recall this was the initial encounter that brought a lot of attention to Mike's efforts):
https://www.youtube.com/watch?v=PUzfR-NtOW4
Otherwise, not execting to hear much new before the Jan.-Mar. winter period... and quite possibly, nothing then.

-- I Get Emails (...plus IBWO Speculation) --
(1935 Arthur A. Allen, Singer Tract) |
Several seabirds spend almost their entire lives far out at sea. Chimney Swifts spend a remarkable percentage of their lives in the air, coasting on the wing. Even warbler species have fairly specific physical niches they inhabit and don't depart from much… some rarely encountered more than 20 feet off the ground, others rarely found lower than 40 feet high. All bird species adapt to fit niches, sometimes narrow ones...
A couple of weeks ago someone sent me a picture of bark scaling, they thought interesting, at the base of a large tree trunk. I don't think there's any chance it's Ivory-bill work, but I'll get back to that in a moment.
Over the course of this blog people have occasionally sent me pics and audiofiles they find interesting of things encountered in their outings.
Unfortunately, in 9 years, hardly a single photo, kent sound, or double-knock sent my way has looked/sounded very promising to me. Double-knocks are hard to judge (and highly ambiguous), especially on often scratchy or muffled recordings so I can't rule out IBWOs on many of them… but I also can't rule out a multitude of other sound-alike alternatives. "Kent" sounds that people have sent along rarely sound like IBWO to me (sometimes I can't even tell why the sender finds it interesting); I can only remember one, or perhaps two, such recordings sent in that really made my ears prick up quite a bit (I've forgotten now if that was from Arkansas or Florida); and, in any event, again there are a LOT of ambiguous, kent-like sounds possible in the woods. Nor has any photo of a bird sent my way been cause for excitement. Lastly, folks send photos of cavities and foraging sign -- again, none very compelling (though some more interesting than others). I don't want to discourage people from sending such things along (...I'd rather view 100 worthless pics, than risk missing out on the one photo that actually 'rings my chimes'), but I do want folks to realize that the chance of getting a positive response from me is incredibly slim, especially if you yourself can't determine what you have -- but if you do send something, please include as much additional information/details as you can that might add any significant context to the attachment that I'm viewing/hearing.
Anyway, back to the more recent (bark-scaling) photo… basically I don't believe that any current-day IBWO would forage low on a tree trunk for any significant amount of time -- depending on the nature of such scaling, there are numerous other possible critters from deer, bear, beaver, squirrels, wild boar, humans, that might cause such damage.
I'm in the camp that believes any remaining IBWOs have evolved heightened wariness and caution, and as such DO NOT spend ANY extensive time at ground level, where they would be far more vulnerable. In fact, I believe they are now almost exclusively residents of the upper canopies, other than when flying from point A to point B and requiring a clear pathway. While they might land momentarily lower on a tree, they probably spend most of their daily lives minimally 35+ ft. high up (maybe 50+ ft.) on tree trunks/branches and inside cavities, well above levels frequented by Pileateds and other woodpecker cousins (and generally out of easy sight-line for searchers). It's not clear to me how many of the remote automatic camera traps were ever set that high (though it's clear several were not). Like Swifts in the air and Albatrosses at sea, I think Ivory-bills may spend most of their lives solely in the canopies… if you send me a photo of foraging sign or a cavity or a fuzzy bird lower than ~35 ft. high, I probably won't take it too seriously (even though there are historical records of such cases), unless there are overriding additional details to catch my attention. If Ivory-bills currently lived and foraged below 35 ft. to any significant extent I believe we'd have the definitive evidence we need by now (well before now!); only perhaps as a denizen of the upper reaches might they be able to carry on successfully, while also evading encounters and detection to the degree they have.
I recall a veteran birder once imploring other birders (who missed interesting birds flying overhead), "always look up (...unless you're driving down the road!)" ...perhaps, just perhaps, in the case of the Ivory-bill no truer words apply.

A wildfire was put out quickly this week in Ojito de Agua, part of Alejandro de Humboldt National Park of eastern Cuba, one final possible home of the Ivory-billed Woodpecker in the 1980s:
http://www.cadenagramonte.cu/english/index.php/show/articles/18902:firefighters-extinguished-fire-in-record-time-in-eastern-cuba
Sorry, for the 2-month lapse in news here (longest in history of the blog I believe), but am not expecting much news through the summer months, and pretty busy with other things. Otherwise, for those wondering, all is well here other than the sparsity of news worth passing along.
I have been asked to mention that just last weekend well-regarded ornithologist/conservationist/museum curator David S. Lee tragically passed away. His main work was in other areas, but he had a sighting of a female Ivory-bill in central Florida back in 1967, at a time many claims, never fully substantiated, came from that state.

Yet another story of a leucistic Pileated Woodpecker today, this one in Thomasville, Georgia:
http://tinyurl.com/kwkqmvb
[some other leucistic Pileateds on the Web here: http://tinyurl.com/npnhppo ]
It calls to mind yet another conundrum of the Ivory-bill situation. One thing I expected from the USFWS/Cornell searches, even if adequate documentation of Ivory-bills wasn't attained, was a very honed-down list of serious locales for further study, from the prior many possibilities. But after years of major, costly, wide-scale searches, we have an even wider list of prospective locales for study, than we had before. Incredible!
It makes little sense that this species could reside in so many widely disparate areas, for so long, and yet not be adequately documented in 70 years. People will try to account for it by the bird's nomadic nature in search of food, but this hardly seems adequate, to explain a species possibly stretching from S.C. to east Texas, from Tenn. to the Gulf of Mexico, in such puny numbers, yet breeding successfully for decades.
I wrote here long ago that one thing that might account for the number and wide range of IBWO reports (the credible reports, once the weakest claims are discarded), would be leucistic Pileateds that by sheer coincidence mimic the markings of IBWO. I was heartened by the fact that, with the single exception of a Noel Snyder verbally-reported bird decades ago, I've never seen nor heard of such a Pileated ever being found (that actually looked like an Ivory-bill). But, still one wonders… if such birds do exist, they are certainly few and far between… probably popping up but very rarely in random disparate locations… oh yeah, sorta like Ivory-bills...
In any event, it's good that others are looking for diagnostic qualities in ancillary characteristics like foraging/scaling sign, flight style/speed, wing ratios, audio soundprints, etc., even if not conclusive, since rapid visual identification itself is now so widely-regarded as inconclusive.
Just a quick ADDENDUM, since an emailer writes that they don't see how any of these 'mutant' PIWOs could be mistaken for an Ivory-bill in the field: so to stress again, I'm not concerned about these specific leucistic individuals that have been documented, but concerned about what their parents, siblings, offspring, and cousins, who we may not have encountered, look like... leucistic patterns amongst them, or yet other PIWOs, could, by sheer genetic chance, follow far more IBWO-like patterns than the specimens shown here.

-- Fermi's Paradox… The Drake Equation --
-------------------------------------------------------------------
Caution: long-windedness ahead….
Off-and-on I read a fair amount of popular physics, often running across "Fermi's Paradox" along the way.
I've never quite understood how anyone could take such a paradox seriously (or, indeed, how a competent physicist could've concocted it). And then I suddenly realized why I have this immediate aversion to Fermi's so-called paradox… it parallels somewhat the "paradox" of the Ivory-bill situation!
For those unfamiliar, here's a synopsis of the Fermi case adapted from Wikipedia:
************************************
'Fermi's paradox is the seeming contradiction between the probability that extraterrestrial civilizations exist in our galaxy and humanity's lack of contact with, or evidence for, them; the basic argument running as follows:
a) There are billions of stars in the galaxy, billions of years older than our Sun.
b) Some, perhaps many, of these old stars have Earth-like planets suitable for evolving intelligent life.
c) Some of these older civilizations would long before now have developed interstellar travel; a technology Earth is only just now investigating.
d) And once interstellar travel is achieved, the galaxy can be colonized, such that by now we should have had contact.
In short, the Earth itself should already have been visited. Yet there's no convincing evidence of such, nor any confirmed signs of intelligent life elsewhere, even in the more than 80 billion+ galaxies of the known universe. Thus, Fermi's question, 'Where is everybody?'
************************************
Or, in a different context, 'Where are those dang Ivory-bills?'
Fermi's Paradox deals with immense distances (and ages) of interstellar space and then makes huge unknowable assumptions about "development" and 'advanced civilizations,' and our own technological capabilities… BUT, perhaps there are 10 extraterrestrials in my living room right now, but due to my limited perception and their superior means they remain invisible to me… seriously, there's no way to know. Fermi's Paradox relies on using our current primitive, myopic knowledge to adjudge the potential of possible lifeforms millions of years ahead of us, about whom we'd likely understand little… 100 years ago what human would've understood the operation of a current-day smartphone?… I can't imagine what all we don't understand of any alien even 10,000 years ahead of us, let alone a million years ahead (...or, as others believe, perhaps every civilization much older than us, has already killed themselves off, as some theorize all advanced civilizations do). The whole matter is a preposterous thought exercise, fraught with pitfalls.
Similarly, at the other extreme, is the Drake Equation, which seems equally ridiculous -- Drake's Equation purports that there are almost certainly 1000s of other intelligent civilizations (in the Milky Way galaxy alone) based on values plugged into a certain contrived equation (though BTW, I don't object so much to the equation itself, but just to the idea that we can accurately determine valid, meaningful numbers to plug into it).
Both Fermi's Paradox and the Drake Equation are the sorts of things one could expect sophomore physics majors to argue over after a Friday night of late beer-imbibing… that professional physicists seriously discuss them boggles my mind. Both are too simplistic, and too chockfull of things unknown.
Anyway, the point is, this situation nicely parallels the Ivory-bill debate in some ways:
In the IBWO case we are dealing, not with vast distances of interstellar space, but great swathes of remote, barely-penetrable earthly groundspace, with beings that, if they exist, are few and far between, and easily missed etc. etc. (you've heard it all before) -- it is not so paradoxical that IBWOs should be exceedingly hard to find, hard to photograph, and hard to document at a level of certainty, anymore than finding alien life, even after decades of high-tech searching, should be easy.
On the opposite side of the spectrum, analogous to Drake's Equation, there is no amount of math or statistics one can slap onto Ivory-bill data (such as it is), that will be tight enough, conclusive enough, to say, "Ivory-bills exist" -- at this point ONLY direct, clear, well-documented, unarguable (and preferably repeatable), photographic evidence of living Ivory-bills will accomplish that… otherwise, the unknowns, the variables, the disputed assumptions and subjective elements whenever "analysis" is required, are too many. I don't make the rules, am just reporting how they seem to have evolved. We need evidence that EVERYbody agrees on, not evidence that requires extensive analysis.
[As a sidenote, there is BTW, one paradox that DOES concern me: it's one thing for humans to have difficulty encountering IBWOs, it's another for non-thinking, non-tiring, 24-hour-working cameras to fail to encounter the bird. Despite 1000's of hours of automatic, remote camera-recording (literally millions of picture frames) from habitat, cavities, and foraging sites that appeared favorable, we have utterly failed, over years, to detect a SINGLE Ivory-billed Woodpecker -- even though these birds must, to exist at all, regularly forage, roost, fly about, breed, etc. This is the single most devastating result of the entire USFWS/Cornell search -- having said that, I'll quickly add that the cameras (which often malfunctioned, BTW) were used in relatively few areas -- compared to all the suitable habitat available. Still, cameras were placed where, following much study, the best chance of capturing an Ivory-bill on tape was anticipated -- either Ivory-bills were not there, despite prior alleged evidence that they were, or we humans are bumblingly, mind-blowingly incompetent at ever understanding/predicting this species' behavior (personally, I'm voting for the gross friggin' human incompetence option, but I could be wrong, maybe they aren't there)].
Anyway (getting back on track), "FAV" asks in a prior comment what I think the bird is in Mike Collins' "flyunder" video. The problem with all of Mike's videos (and the "flyunder" clip is one of the more intriguing ones) is simply that the quality is too low. [Mike's own analysis of the "flyunder" clip is here, with the key footage and discussion beginning around the 3:50 mark.] Mike, FAV, some others think they can draw empirical, analytical conclusions from such graininess; others don't believe the precision required is possible. Strong skeptics would put it simply as, "Garbage in, garbage out." I wouldn't go that far… you can definitely tease information out of garbage, but it tends, of necessity, to be limited and speculative, especially when human subjectivity enters the mix.
So I don't feel as confident about the precise size, features, or even speed of the "flyunder" bird as FAV does. Even if the white appearance (or is it gray) of the dorsal wing, for example, is real (not some sort of artifact) it is too extensive for an Ivory-bill, so glare or photographic 'bleed' must be involved, but if bleed is involved than how much; 10%, 70%? I don't know all the specifics of the sunlight that day, or angles, or atmospheric conditions, or all the camera specifications, that may have affected filming or the look of a distant fast-moving object. As Donald Rumsfield :-( would say, I don't even know all the things/variables that I don't know. Maybe Mike's analysis is spot-on, but, for plenty of reasons, most folks aren't persuaded.
FAV asks which of 10000 species that bird could alternatively be… I WISH I could glean enough indisputable detail to make a good guess. But if my choices are, it's either an Ivory-bill, or it's one of 9999 other species, including possibly a leucistic individual, then I'm not willing to stake my choice on the former, based on this degree of detail. It's too easy, as optical illusions repeatedly demonstrate (and Sibley of course states), to fool ourselves. (...I happen to think the bird in the Luneau video is most likely an Ivory-bill, but again, based on that clip's poor quality, I'm unwilling to assert with certainty, it's even a woodpecker.)
We all know where Mike stands on his evidence… if he wants it to gain any more traction at this late point he needs to have a reputable but independent party, who hasn't already committed themselves in the IBWO debate, analyze the film clips and reach the same conclusions he has (and publish or post it somewhere)... No one in the broader birding community will assume that I or Mike or FAV are objective or impartial parties at this point on IBWO matters. Serious evidence needs to be looked at by other detached, but competent, third parties, whenever possible; even Cornell and USFWS are largely viewed as tainted in this arena, by now.
Like me, I imagine Cornell continues to receive an ongoing trickle of Ivory-bill "sightings" that are so weak (and sometimes comical) that there is no point in publicizing them and adding to the ridicule that already abounds. Similarly, even if say, Bobby Harrison has had 10 more sightings by now, I suspect he knows he'd be foolhardy to announce it publicly, without photographic evidence, accompanying.
So, I love Mike and FAV's passion and persistence, but they don't seem to understand that we're well past the time when even interesting, tantalizing, intriguing, but ultimately fuzzy evidence requiring interpretation, gets us very far. Collecting, analyzing and discussing grainy evidence is fine, but asserting conclusive results from it, and dissing those with different interpretations, won't fly in today's atmosphere. When/if the species is definitively, conclusively documented, there will be plenty of time for dissing! ;-)
Anyway, while skeptics argue from the Fermi perspective, FAV and Mike argue from the Drake perspective… and the nice thing for me about having them around, is that they make me seem like a moderate!
-------------------------------------------------------------------
Caution: long-windedness ahead….
Off-and-on I read a fair amount of popular physics, often running across "Fermi's Paradox" along the way.
I've never quite understood how anyone could take such a paradox seriously (or, indeed, how a competent physicist could've concocted it). And then I suddenly realized why I have this immediate aversion to Fermi's so-called paradox… it parallels somewhat the "paradox" of the Ivory-bill situation!
For those unfamiliar, here's a synopsis of the Fermi case adapted from Wikipedia:
************************************
'Fermi's paradox is the seeming contradiction between the probability that extraterrestrial civilizations exist in our galaxy and humanity's lack of contact with, or evidence for, them; the basic argument running as follows:
a) There are billions of stars in the galaxy, billions of years older than our Sun.
b) Some, perhaps many, of these old stars have Earth-like planets suitable for evolving intelligent life.
c) Some of these older civilizations would long before now have developed interstellar travel; a technology Earth is only just now investigating.
d) And once interstellar travel is achieved, the galaxy can be colonized, such that by now we should have had contact.
In short, the Earth itself should already have been visited. Yet there's no convincing evidence of such, nor any confirmed signs of intelligent life elsewhere, even in the more than 80 billion+ galaxies of the known universe. Thus, Fermi's question, 'Where is everybody?'
************************************
Or, in a different context, 'Where are those dang Ivory-bills?'
Fermi's Paradox deals with immense distances (and ages) of interstellar space and then makes huge unknowable assumptions about "development" and 'advanced civilizations,' and our own technological capabilities… BUT, perhaps there are 10 extraterrestrials in my living room right now, but due to my limited perception and their superior means they remain invisible to me… seriously, there's no way to know. Fermi's Paradox relies on using our current primitive, myopic knowledge to adjudge the potential of possible lifeforms millions of years ahead of us, about whom we'd likely understand little… 100 years ago what human would've understood the operation of a current-day smartphone?… I can't imagine what all we don't understand of any alien even 10,000 years ahead of us, let alone a million years ahead (...or, as others believe, perhaps every civilization much older than us, has already killed themselves off, as some theorize all advanced civilizations do). The whole matter is a preposterous thought exercise, fraught with pitfalls.
Similarly, at the other extreme, is the Drake Equation, which seems equally ridiculous -- Drake's Equation purports that there are almost certainly 1000s of other intelligent civilizations (in the Milky Way galaxy alone) based on values plugged into a certain contrived equation (though BTW, I don't object so much to the equation itself, but just to the idea that we can accurately determine valid, meaningful numbers to plug into it).
Both Fermi's Paradox and the Drake Equation are the sorts of things one could expect sophomore physics majors to argue over after a Friday night of late beer-imbibing… that professional physicists seriously discuss them boggles my mind. Both are too simplistic, and too chockfull of things unknown.
Anyway, the point is, this situation nicely parallels the Ivory-bill debate in some ways:
In the IBWO case we are dealing, not with vast distances of interstellar space, but great swathes of remote, barely-penetrable earthly groundspace, with beings that, if they exist, are few and far between, and easily missed etc. etc. (you've heard it all before) -- it is not so paradoxical that IBWOs should be exceedingly hard to find, hard to photograph, and hard to document at a level of certainty, anymore than finding alien life, even after decades of high-tech searching, should be easy.
On the opposite side of the spectrum, analogous to Drake's Equation, there is no amount of math or statistics one can slap onto Ivory-bill data (such as it is), that will be tight enough, conclusive enough, to say, "Ivory-bills exist" -- at this point ONLY direct, clear, well-documented, unarguable (and preferably repeatable), photographic evidence of living Ivory-bills will accomplish that… otherwise, the unknowns, the variables, the disputed assumptions and subjective elements whenever "analysis" is required, are too many. I don't make the rules, am just reporting how they seem to have evolved. We need evidence that EVERYbody agrees on, not evidence that requires extensive analysis.
[As a sidenote, there is BTW, one paradox that DOES concern me: it's one thing for humans to have difficulty encountering IBWOs, it's another for non-thinking, non-tiring, 24-hour-working cameras to fail to encounter the bird. Despite 1000's of hours of automatic, remote camera-recording (literally millions of picture frames) from habitat, cavities, and foraging sites that appeared favorable, we have utterly failed, over years, to detect a SINGLE Ivory-billed Woodpecker -- even though these birds must, to exist at all, regularly forage, roost, fly about, breed, etc. This is the single most devastating result of the entire USFWS/Cornell search -- having said that, I'll quickly add that the cameras (which often malfunctioned, BTW) were used in relatively few areas -- compared to all the suitable habitat available.

-- Flights... of Fancy --
------------------------------------------------------------------
For what it's worth, just some videos I've lumped together (essentially, meaning I've had a wee bit too much free time on my hands this week...):
The famous Rhein video of an Imperial Woodpecker (Mexico) showing it taking flight around the 1:12 and 1:20 timepoints:
A couple of clips showing a Pileated Woodpecker in flight:
And a couple of clips of Pintails in flight (the species often historically compared to an Ivory-bill in flight):
I don't know all the specifications of these clips in terms of film speed or any de-interlacing, so wouldn't read too much into the perceived speed of the flights... but am more interested simply in the style or giss of the flight patterns (wingbeat speed, as a topic, is actually covered more fully in this old Bill Pulliam post: http://bbill.blogspot.com/2011/11/woodpecker-wingbeats-revisited.html).
The Luneau Arkansas video, by the way, is here:
http://www.sciencemag.org/content/suppl/2005/06/02/1114103.DC1/1114103S1.mov
and a couple of Mike Collins' Pearl videos as well, here:

-- Tidbits --
-------------------------------------------------------------------
1) A Mississippi journalist voices support for Mike Collins here:
http://www.sunherald.com/2014/04/12/5491527/legends-of-honey-island-swamp.html?sp=/99/228/263/490/
2) Occasionally, my Ivory-bill feeds bring in something I don't even know what to think of… the below page contains a couple of oddball quotes from a "Caleb Nelson" -- at first I assumed they were historical in nature, but turns out Caleb Nelson currently teaches at the UVA School of Law (perhaps the whole page is strictly intended as humor?); in any event, Virginia is beyond the historical range for the IBWO:
http://www.lawweekly.org/?module=displaystory&story_id=4107&edition_id=248&format=html
3) Someone emailed me recently asking how many searchers were employed in the official USFWS search throughout the Southeast, and I don't have any figure for that (there were also a lot of volunteers and independents who only worked short stints). I quickly scanned through the final FWS report and what seemed clear was that only Arkansas, Florida, and South Carolina really had very many active searchers (and even then not enough to cover all the habitat of interest). Mississippi, Georgia, Louisiana, Tennessee, and perhaps even Texas, had remarkably few searchers (although La. and Tx. have been covered a lot in the past). But if anyone wants to put more exact figures on it feel free to.
4) Finally, I've seen some pretty major tree work done by Pileateds in the past, but still found this recent addition to YouTube impressive:

-- Memory Lane --
-------------------------------------------------------------------
First, "ChiricahuaBob" has added a couple more entries to those cited in the prior post, about further areas in Florida worth exploration:
http://www.ibwo.net/forum/showpost.php?p=6285&postcount=272
http://www.ibwo.net/forum/showpost.php?p=6286&postcount=273
A quick note that in the second post C-Bob refers to "the Green Swamp in NC FL," and though it's clear from the post he's referring to an area in NorthCentral FL., just to clarify, I'll note that there is likewise a Green Swamp ("Wilderness Preserve") in southeast North Carolina (NC) that has also had IBWO rumors over the years (…maybe Bob should check it out!). BTW (and I hesitate to even mention this), the FL. Green Swamp is one of the areas the infamous "Magic Bill Smith" early-on made IBWO claims for.
Speaking of Magic Bill, I had occasion recently to go back and re-read some of the discussion from the old, hot-and-heavy international BirdForum thread on Ivory-billed Woodpecker updates (I don't know, is that still the longest thread they've EVER had!?)… anyway, quite a trip down memory lane, and a cast of characters… an interesting way to jiggle the ol' memories a bit. It starts here (but takes a little while to really get going):
http://www.birdforum.net/showthread.php?t=33968
You can almost click randomly anywhere in the middle of the
More recent, but still re-hash, is the below brief interview clip with David Sibley, from another site. In it he responds to what I suspect is one of his least favorite questions… what to say about the Ivory-billed Woodpecker:
David is one of the most congenial, soft-spoken, skilled and insightful field birders in the country, and I suspect he is restraining himself mightily here from saying what he actually thinks ;-) (i.e. that the IBWO saga was a wild goose chase and an incredible waste of time, energy, and conservation dollars). At any rate, David remains one of the most respected birders/naturalists around (who's opinion carries tremendous weight in the birding community) so please keep any comments here as civil as David is.
With that said, however, I'll repeat the story I've told previously:
Around the year 2000, after the David Kulivan Louisiana IBWO sighting I was in line at a book signing for Sibley when I reached the table and quickly asked him what he thought of Kulivan's story and the chances of Ivory-bills still being around. Without missing a beat, he answered that he thought it was close to impossible… that with SO MANY birdwatchers around these days and the IBWO being such a LARGE bird, there was almost no likelihood it could have gone undetected for so long. With a line of fans behind me, I didn't have time to argue the points, but it made me aware that David's mind was already largely made up (years before the Arkansas story came along) that the Ivory-bill was extinct, though his reasons seemed simplistic… big birds that spend most of their time either inside cavities, or high in tree canopies in remote dense forests, can fairly easily evade human encounter. And despite the great growth in birdwatching as a hobby the actual number of experienced birders who spend any significant time in IBWO-like habitat remains very small. So at that time, the species' possible survival, seemed well within the possibility realm to me. Today, after larger-scale, longer-term, and better organized searches it's tougher to argue the points, but still the immensity of difficult habitat, requirement for a clear photo or video, and ongoing smattering of possible credible encounters, do keep hope alive.
IBWO sighters, without a photograph, will always be accused of seeing what they want to see, but the skeptics' default position of incredulity is similarly a very predisposing position… as it was 70+ years ago when no one believed Mason Spencer's claim that he saw Ivory-billed Woodpeckers… until, that is, he shot one.
