I s'pose I have some ambivalent feelings about this, but iconoclast Stewart Brand (with others) has a current project underway, called "Revive and Restore" to bring back-to-life various extinct species, using modern genetic techniques. Although their current focus is on the Passenger Pigeon, both the Ivory-billed and Imperial Woodpeckers are among other candidate species being considered.

-- Replay --

-------------------------------------------------------------

For any who may be interested, someone named John Deamond has pieced together this video of various IBWO-related clips (there seems to be no accompanying audio). The first minute-or-so are some very quick clips, mostly zoomed, that have made claims of showing IBWOs (some from YouTube, some from Mike Collins, 1 from Geoff Hill's group). The next 11 minutes are various replayings of the Luneau clip from Arkansas, and the last minute is some superfluous animation:

I don't find anything distinctly helpful or new here, but pass it along in the event others may wish to play with it. Also, don't know any particulars about John's project beyond his own statement that it is "...about extinct birds and how the events surrounding and following their demise reflect issues with how we deal with the natural environment."

-- Random Thoughts on a Hot Summer Night --

-------------------------------------------------------------


Often I let such things go, though sometimes they wear on me a bit… mislabeled pictures of an "Ivory-billed Woodpecker" (with a photo of a Pileated) continually appear on the Web, simply adding to the widespread confusion that stiiiiill exists over these 2 species even after all this time. 

(Ivory-billed Woodpecker... NNNOT!!)

Mislabeled pics on the Web are especially egregious because of the way they are picked up by others and transferred along, so even if the originating site eventually corrects their depiction, the inaccurate picture may have already traveled on, unchecked, repeatedly far and wide. 
Likewise, I've lost track of how many videos on YouTube have appeared claiming "Ivory-billed Woodpecker" for a bird that is clearly something other (and there are other Web video sites that I don't track closely enough to even know how often the same mistake occurs elsewhere).
 It's even more disconcerting that many of these claims emanate from poor habitat or simply inappropriate states (New York, Washington state, Arizona…). Although, most of these cases are probably sincere mistakes, it's also clear that some are instances of prankish individuals wishing only to mess with other people's minds. Getting a good, clear sighting, let alone photo of an Ivory-bill, in good habitat remains a daunting task.

Even National Geographic (a site many would presume credible) for years carried a lead photo of a Pileated Woodpecker above a 2006 Web article on the IBWO search, entitled "The Ghost Bird"… a photo that got picked up and used by others referencing it as an "Ivory-billed Woodpecker." Is it any wonder that IBWOs continue to get ID'd mistakenly in the field by novices and ill-informed individuals, sometimes literally relying on an incorrect picture seen on the Web… or, is it any wonder that others now pretty much automatically dismiss any and all such claims… still, each and every claim and picture coming forth must be looked at individually and adjudged on its own merits… not judged or generalized about on the basis of all that has preceded it.

Science is not (nor ever has been) the pristine activity some uncritically view it as. In recent months many 'scandals' (of varying seriousness) in scientific publications have emerged. One of the most widely followed has been the so-called "arseniclife" or "arsenicgate" story in which a NASA-based study claimed the discovery of a bacterial life-form employing arsenic in the place of phosphorous in its DNA (a monumental biology finding). One likes to imagine that NASA pretty well knows what it's doing scientifically, but following the much-ballyhooed announcement a near immediate firestorm of Internet-generated criticism began throwing cold water on the claims. For now, the original authors continue to defend their results, even while refutations have been published and few seem to take the initial claimants very seriously. 
It is reminiscent of the 1989 Fleischmann/Pons report of creating tabletop cold fusion in the lab, which was likewise quickly shot down by the majority of the scientific community. Mistakes (...or merde ;-)) happen. There have been many instances of fraud in science in recent times; these last two examples aren't instances of that… just mistakes, over-anxiousness, and possibly poor or sloppy science.
 
In some quarters I still see the original Cornell/Nature Conservancy pronouncement of Ivory-billed Woodpeckers in the Big Woods characterized as a "hoax" or "fraud." It is clearly a MIS-characterization (for what, at worst, was weak science), but again, once on the Web it will carry well into the future, to many future newbie students… IF, the IBWO is never confirmed.

Happy Holiday! to my US readers… and Happy Higgs Day! to my European readers (and science buffs EVERYwhere!)… now that 'The God Particle' is being confirmed, perhaps the Lord God Bird will follow… ;-)

anyway, just one actual IBWO note of curiosity today:

I recently clicked to Louis Bevier's honed (skeptical) site on the Ivory-bill debate, only to find it gone:

http://web.mac.com/lrbevier/ivorybilled/Overview.html

Having not visited for several months, not sure when it went down, but apparently Apple dropped that particular domain from use at some point. So I surmise that either…

1) Louis, purposely or accidentally, let the site disappear, since he has the hard data and may feel the debate is long-settled, so no need to continue the Website... (or he may be re-working the material to re-post the site).

2) or, if by chance he is planning to publish further, extended material on the matter (in an academic journal), he may have felt no need to keep the Website up-and-running with a more formal publication in the offing.

3) or, he may simply be tired of being associated with the entire IBWO topic at all and moved on.

There are other possible explanations as well I s'pose, so if anyone knows more, or if his site can be found at some new URL, please let us know.
You can, by the way, still find most of the text portions of Bevier's old site via the Internet's Wayback Machine here:

-- Book Review --

--------------------------------------------------------------

I previously promoted Canadian Tom Gallant's recent novel, "The Lord God Bird," before actually seeing it, and now with so little other news to report, and having read it, I may as well do my own review….

First, one should know that I can count on the fingers of one hand (and not including the thumb!) the number of novels I've read in the last 20 years, so I ain't the finest judge of fiction (in fact I tend to be hyper-critical of it)! It takes a work like Gallant's to even grab my (prejudiced) attention much, and spend $$$ on a novel.

With that said, I recommend this quaint and odd little book to all Ivory-bill aficionados in particular, and nature readers more generally… I want to say that upfront, because I don't want the criticisms ahead to be taken too weightily.

Gallant's writing is about as terse and abrupt as any I've encountered, and yet still descriptive. The nameless main characters are (possibly paradoxically) both sparsely, yet richly, drawn out. The writing is almost too spare and pithy for my taste, but in a short volume, it nonetheless works well, and will please most readers. The overriding effect is that of deep 'truths'/insights being continuously but nonchalantly proffered to the reader from the main protagonist.

The story is surprisingly close in general pattern to actual events of the last several years: a local Arkansas outdoorsman (who remains nameless throughout) spots an Ivory-billed Woodpecker in the Big Woods of Arkansas, and the news soon travels to the ivory-towered world of the Cornell Lab of Ornithology. Two representatives from there visit the area and quickly also spot the bird, bringing in even more academic types and volunteers for a more thorough search of the area… sound familiar? 
Obviously, the book is based on the real events that this blog has followed so closely for the last 6 years, yet its unfolding story is told in a completely fictionalized form, so while the pattern sounds familiar, the details differ greatly. I find it a bit odd that Gallant chose to stay as close to an actual sequence of events as he did (when he had an immense world of fictional possibilities to draw from)… but having done that, I find it odd that he didn't choose even more of the events from the last 6 years that were available to weave into the story. There have been so many elements of the Ivory-bill saga that could be fictionalized into interesting twists and mysteries and storylines… I think he missed a lot of potential opportunities here; but this book is more a succinct and heartfelt telling, than a highly-involved weaving.

For me, the novel takes off with chapter 3, when the Ivory-billed Woodpecker itself comes on stage as an anthropomorphically-thinking/'speaking' character. The anthropomorphized Ivory-bills are something you will either read and find off-putting… or, read and tear up at. For most readers of this blog I hope it is the latter. For me it is a centerpiece of the volume; a sort of flight-of-fancy element that lets the story carve out a special niche, as we surreptitiously gain access to the thoughts/'feelings' of the iconic species. In fact, I would've liked to have seen a lot more of it in the pages.

In chapter 8, "Ron" and "Steve" from the Cornell Lab of Ornithology enter the scenario, and as so often happens in fiction, begin playing the role of 'outsider' academics cast into the real world of the main character who is wary of them. I won't go much into the details of the storyline, nor the ending, so as not to spoil it for any readers. Much of the narrative is about the relationships that develop between the main character and the varied others who enter his world following his sighting. The main character's outlook and 'philosophy' of sorts is also an ongoing thread throughout these pages. And there are of course many interludes, focused on the action of the Ivory-bill 'characters' as well, as they succeed and fail and succeed again at raising young, while warily watching the human invasion of their premises. The story moves along at an easy-flowing pace; sometimes a bit predictable, but not too predictable. And the ending pleases.

On the critical side I felt the volume suffered from some choppiness, some under-development, and possibly some factual glitches, but overall was a wonderful effort for a first-time novel (Gallant has previously written non-fiction). It is a somewhat lyrical ode to nature, though possibly not quite as lyrical as I was expecting or hoping for. At times, for me, the volume alternated between being a simple pleasant human story and being a loftier work, on the verge of soaring... but never sustained its loftiness long enough. The ending is poignant and a tad haunting, but could've been even more powerful (that's just my take, as someone inordinately wrapped-up in this species, and who may have held unrealistically high expectations that the book couldn't attain). One of the advance blurbs on the book's back cover calls it a "sweet uplifting parable for our times." I think that's as good a 6-word summation as I could offer.

Four times in the last 20 years I have myself started writing (and failed to finish), an Ivory-billed Woodpecker book: 3 of those efforts were non-fiction (each with a quite different approach), but one was a novel.  The novel I envisioned carried a different plot than Tom's book, but a somewhat similar tone, 'feel' or 'mystique' to what Gallant has created here. His is a crisper, probably simpler, story than I had in mind, and I'm thrilled he told it. So despite the mild criticisms, I do heartily recommend it to all who are enamored of this iconic bird, or simply in search of an enjoyable nature story. I'm glad someone took the time to write it (and, in the process, to exhibit so much respect for the subject)… the Ivory-bill deserves no less.

With so little to report, I'll just mention that Jack Hitt's latest book, "Bunch of Amateurs," includes a long chapter on the whole Ivory-bill escapade since Cornell's original announcement (and the role of "amateurs" in that escapade). I've previously linked to this NY Times article of Hitt's which includes some of the same info he used in his book:

http://www.nytimes.com/2006/05/07/magazine/07woodpecker.html?_r=1&pagewanted=all

(not sure if everyone can directly open the link or if you'll need a free registration with the Times to access it)

Since I expect ensuing months to be slow for IBWO news I'll put out a call as I did once before:

...If anyone who has been involved at some level with the IBWO story over the last several years is willing to submit to an interview as I've done in the past (answering transcribed questions, not an audio or podcast), let me know. This could be anyone who thinks they have a viewpoint or information worth sharing, either from the 'believer' or skeptical side, positive or negative…. Assuming I know of you in some guise just email me (cyberthrush@gmail.com) with a note indicating a willingness to be interviewed. If by chance I might not know of your role in the whole IBWO endeavor then please explain in the email your background and what you feel you may have to offer (so I can figure out what sorts of questions to pose for you). Don't everyone volunteer at once!….

Sometimes I skip over reporting on non-documentary Ivorybill-related movies, novels, stories, and the like here… enough folks already regard the content of this blog as fiction ;-) without me bringing up deliberate outputs of fiction. But the reviews I've seen for a recent novel set in the Big Woods of Arkansas, entitled "The Lord God Bird" by Tom Gallant, are too good and positive, not to pass this one along (haven't read it myself, but haven't seen a single bad review).

From the publisher:

"Infused with captivating imagery and spare, assertive prose, The Lord God Bird explores the vibrant spirit of a wild creature in a way no nonfiction work ever could. This is a profound, yet hopeful, meditation on the way humans relate to the natural world."

-- Florida Dreaming --

--------------------------------------------------------------

 May closes out soon and with it, summer overtakes the southeast… summer heat, humidity, foliage, bugs, snakes…. If any Ivory-bills fledged this spring they may just now be beginning to travel around the forest greenery with their parents, just as Ivory-bill searching is largely forced to wind down to a standstill.

Not too much new to report (a few re-hash articles have been on the Web), so I'll just toss out the little bit of visual entertainment I can find: 

First this nice-sounding double-knock apparently recorded in the Choctawhatchee (around the 5-6 second point; & turn your volume up):

 

the fellows recording it made a pleasant companion travelogue of their venture (no additional IBWO material though):

 

From the serious (I assume/hope) to the oddball… an individual on Facebook casually claims the recent sighting of 2 Ivory-bills on a tree somewhere in central Florida (outside Gainesville, I believe, but not certain), and got at least one blurry photo:

http://tinyurl.com/ctvxwfv

The bird certainly has an interesting posture, size, and neck(!), and is on an interesting tree (though poor-looking habitat), but lacks key features of an IBWO (longer bill, white saddleback) and so it goes....

Here's an artist's rendering of an IBWO in a similar pose:

-- Comedy of Errors? --

---------------------------------------------------------------

..... Seven years ago today, Cornell Lab of Ornithology officials made what may have been either the most incredible, or, ultimately most embarrassing, announcement in the entire history of American ornithology. Some of us are still awaiting a verdict on that announcement… (while others have long-past made up their minds). And seven years later, no final compendium of the official search, as promised, has been forthcoming; in fact the principals largely steer clear of public Ivory-bill discussion now -- what was once a great fund-raising tool would now virtually be a fund-raising obstruction. 
But the topic continues....

Many (unfortunately) will view last week's mini-fiasco at a local Texas TV station (implying first a Red-headed Woodpecker and then later a Pileated Woodpecker were putative Ivory-bills based on one local observer) as the mere continuation of a (perceived) comedy of errors begun 7 years ago.

Every few months I still get via email a claimed Ivory-bill sighting from somewhere… and I suspect others in the ornithology community hear a lot more stories than I do. Claims for Ivory-bills continue to show up on websites, including Twitter and Facebook. And YouTube receives several "Ivory-bill" videos each year. In short, even after all this time and publicity, claims from the inexpert and inexperienced roll in… and I don't blame people (too much?) for getting excited and jumping to false conclusions based on limited knowledge. …It is odd though when out-of-the-blue, one of these multitudinous claims makes it directly onto a TV station. So, I do blame a knucklehead ;-) news station when they take such a story and run with it to a mass audience without the simplest of verification (the Texas story was no doubt used, because it included video… but THAT of course is exactly why it could've so easily been researched and junked!). 

I won't recount the full story here; it's already received more publicity than it ever deserved. One suspects the primary station involved was deluged with a range of polite to riled corrections from a throng of birders/biologists… but I also suspect they simply found it humorous that, in a day of Jihadi terrorists, global warming, and economic plight, folks would so bristle over a mere botched animal/human-interest story. Bristle they (rightfully) did...

Because of the nature of the Internet, and despite a later correction from the broadcast station, the bogus story will continue to bounce around the Web in some quarters for days or weeks, reinforcing the 'laughability' quotient of the whole Ivory-bill topic.
A Texas trademark slogan warns us, "Don't mess with Texas"… I'd prefer to revise that to, "HEYYY, Texas, DON'T MESS with birders… puhhh-leeeze!!!"

Documentary filmmaker George Butler has been working on "The Lord God Bird," the only Cornell-endorsed film account of the IBWO search, as "a work in progress" since the beginning of this Arkansas-based saga. The independent film has been screened sparingly over recent years, and is included in upcoming Earth Day celebrations (next weekend) at the Berkshire Museum in Pittsfield, Massachusetts, if you're in the area:

http://birdstuff.blogspot.com/2007/03/i-just-saw-lord-god-bird.html

The film was originally intended as "the first in a planned trilogy of films dealing with extinction," with subsequent entries to focus on the Royal Bengal Tiger and the Lowland Gorilla.

---------------------------------------------------------------

-- Of Soras, Kitchens, and Paradoxes --

------------------------------------------------------------

Probably ought do a new entry since some readers only read the posts here and miss the comments section… so for any who don't know already, the prevailing opinion to the latest taped sounds from Louisiana is that they are likely Sora rails (I'm not 100% convinced of this myself, but its a moot point since I am convinced they are not IBWO sounds). You can read the comments to the prior post to fill in some of the details, if you haven't already...

One other thing I'll touch on from the comments (and I thank people for not letting them slip toooooooooooo far into 'snarkland' before making your points):

For obvious reasons many (most?) birders no longer wish to involve themselves in the Ivory-bill debate (no doubt wishing it would just go entirely away!). It was suggested in prior comments that the 'mystery' sounds should've been put on listserv groups (including "Frontiers of Identification") for access to a quick, broad range of opinion. I don't believe the "Frontiers of ID" listserv is an appropriate site for most questions that come up here, nor do I think they would even take it seriously (they may even have an unspoken ban on this sort of IBWO material), and I don't fault them for that.

I myself had mentioned a desire to see the question put on the Louisiana birding listserv, though I'm not sure even they would have seriously reviewed it (and I wouldn't recommend it for any other state birding listserv -- by the way, you can't just willy-nilly post things on these listserv groups, but must be a registered member, and that involves a process as well). I do wish that more individuals from the Louisiana Ornithological Society had heard and responded to the sounds, and would still be interested to hear from certain of them.

But the point is, soliciting a wide selection of experienced birder viewpoints is not all that easy anymore when it comes to potential IBWO "evidence." When I occasionally seek opinions on certain questions through backchannels, the response I often get (if any) is along the lines of, "here's what I think, but please don't put it on the blog" or "here's my opinion, but don't attach my name to it." I always respect people's desire for confidentiality, but it does mean that more people weigh in on certain matters than can always be told (though still not as many as I'd like!); at this point 'Ivory-bills' is simply a 'taboo' subject for many who don't want to dabble with it.

I've said before here, if you can't take the heat stay out of the IBWO kitchen… (as David Kulivan, Mike Collins, Geoff Hill, and a li'l outfit called the Cornell Lab of Ornithology etc. can all attest to!); the Project Coyote group seems capable of defending themselves, as they should expect to have to do; other searchers prefer not to even have an internet presence and thus not deal directly with skeptics and criticisms. Part of me wishes that ALL evidence could be immediately laid out on an open table and summarily dealt with by the 'collaborative' Web. But I also completely agree with a colleague who notes that the more 'suggestive' evidence that comes forth without something conclusive following it, the more the IBWO case gets weaker, not stronger. That is the 'paradox' of the IBWO case… the more "evidence" that is produced the WEAKER the argument becomes to the general birding community, UNLESS clearcut photographic or video evidence follows close behind….

-- 'Round and 'Round We Go --

------------------------------------------------------------

Thanks to all who've sent along their thoughts on the Louisiana sounds via email… even though nothing is settled; no one writing me is willing to call the sounds Ivory-bills, but nor has anyone pinpointed a really convincing candidate for what the sounds are -- I'm honestly surprised a good candidate hasn't arisen yet. I think the most difficult thing to account for is the sporadic, unpatterned nature of the calls -- the notes themselves do sound like certain things, but not when given in the rather random sort of series that they appear. As I've been leaning somewhat toward waterbirds as the source for the sounds my best candidate thus far (though it has some problems) is immature Common Moorhen (Gallinule):

http://tinyurl.com/88uozh9

Kinda wish someone would put the calls on the Louisiana listserv -- even if most readers there are likely jaded to Ivory-bill stuff, it still may take just one person, well-acquainted with Louisiana fauna, to hear the tapes and say, "Well it was February, so of course that is ___________", and the riddle is over! -- I'm a believer in the collaborative 'hive mind' of the Web (even as messy as it can be) -- the day of "experts" solving things in isolation is receding (and this 6-year IBWO saga/debacle? of inconclusiveness may be an example of why). Still, would also be good to hear the opinions of David Sibley, Pete Dunne and several others, though they may not wish to publicly wade into such matters. We need to put these mystery sounds to rest as soon as possible… even if it's not Ivory-bills, other IBWO searchers need to know what is capable of such sounds. I've recently put the sound clips on Twitter, but don't expect much feedback from that. (On a sidenote, the last people still alive to have actually heard Ivory-bills in the wild, Nancy Tanner and George & Nancy Lamb have heard the tapes, but are not able to clearly rule in or out the possibility of IBWOs.)

For what it's worth, I think the Louisiana team wishes these latest auditory clips to be viewed not in isolation, but as part of a larger body of work (sightings claims, scaling, anecdotes, etc.) that they've compiled over an extended period of time in the general central Louisiana area they are working. Still, we need lengthy, close-up, detailed observations by multiple observers, at a minimum…. and really, photos/video. (sorry, to sound like a broken record…)

Again (so you don't have to keep jumping back to an earlier post), here are the swamp sounds in question:

--------------------------------------
ADDENDUM: for bird-detective-types ;-), wishing to play around with various sounds themselves, the site I used above, xeno-canto, is here:

http://www.xeno-canto.org/

I like it because it usually has several different examples for any given species; males, females, and juveniles can have quite different calls/songs, and even a single given bird may have a variety of different vocalizations depending upon circumstances.

Cornell has at least 2 sites from which you can listen to bird sounds, their famous Macaulay Library, and their "All About Birds" site:

http://macaulaylibrary.org/
http://www.allaboutbirds.org/guide/search/ac

And a couple other sites here:

http://www.naturesongs.com/birds.html
http://www.enature.com/birding/audio.asp

Finally, even YouTube will often have great examples of bird calls.
-------------------------------------------------------------

-- Update --

------------------------------------------------------------

Not much of an update (read prior post if you haven't already), but I've been listening to the Coyote tapes repeatedly, and received slightly more context about the sounds. My first impression remains the same, that these don't sound (to my ears), like what I'd expect of Ivory-bills… the pitch, tone, cadence, speed, rhythm doesn't maintain itself correctly through the tapes, even though some short bits do sound intriguing (but, I've done no technical analysis). Having said that, I can't pinpoint a good alternative candidate for the sounds either. Certainly though, a great many sources must be considered:

1) various amphibians

2) injured or 'yelping' dogs or other mammals

3) mechanical or artificial (man-made) sounds: bird calls, tools, hinges, equipment etc.

4) I'm not aware of insects that could make these sounds, but would want an entomologist to weigh in on that.

5) just among birds alone, jays, herons, waterfowl, blackbirds, hawks, escaped psittacine birds, vagrants, and perhaps more must be considered

If some of the above suggestions seem outlandish to people, one must understand that the possibility of IBWOs IS outlandish to people… to rule IN such a low probability possibility as IBWOs, one needs to consider and rule OUT all other low probability possibilities. And from what I'm told, several of the above are already considered and ruled out. Process of elimination is a somewhat weak, but necessary, way to proceed (and I would expect spectrographic analysis will rule out all but a few of the above, though not necessarily pinpoint an answer). My own guess is still that there WILL be an alternative explanation for the sounds (this is the time of year a LOT of forest critters begin sounding off!), but admittedly, with each listening I'm having a harder time surmising what it might be.

I'm curious, by the way, of what Nancy Tanner might think of the sounds, if anyone out there can draw her attention to them. Anyone else who cares to weigh in via the comments or privately through email, feel free to do so, as well.
