Nothing new of course (except getting to hear Martin Collinson's fine British accent : - ), and solely focussed on Arkansas and the Luneau video yet again, but worth a look if you enjoy video.
--- All of which reminds me, that Cornell originally said they'd be replying to Collinson's analysis (Pileated vs. Ivory-bill flight comparison), but as yet I've not seen it --- if their rejoinder is indeed out there somewhere and I've missed it, someone please point me in its direction...

-- Congaree Info --
---------------------------------------------------------------------------------------
South Carolina was one of the last places James Tanner believed the Ivory-bill persisted 60 years ago, and the rumors/claims have never completely dwindled. Since it's looking like a lot of attention may get paid to S.C.'s Congaree Swamp next IBWO search season, might be worth reviewing the area a bit. Here's what USFWS employee Bob Russell previously wrote about the Congaree over a year ago at BirdingAmerica:

Since it's looking like a lot of attention may get paid to S.C.'s Congaree Swamp next IBWO search season, might be worth reviewing the area a bit. Here's what USFWS employee Bob Russell previously wrote about the Congaree over a year ago at BirdingAmerica:
"The finest bottomland forest in the east, only 5,000 acres of the 20,000+ acres have been adequately explored botanically (let along for birds!) according to rangers in the park. Knowledgeable birders who enter the visitor’s center will be startled to see James Tanner’s photo prominently displayed. Tanner was greatly instrumental in helping set up this former national monument—did he know something we don’t or did he have suspicions that IBWO were in the area? We’ll never know but presumably he knew IBWO habitat when he saw it and this is the only existing site that rivals the Tensas swamp of old. Don’t bother with the boardwalk and developed trails but strike out on your own by kayak, canoe, or hiking (open understory, relatively easy to walk under the climax overstory) and check out remote areas of the park. Shouldn’t take you more than 2-5 years of your life.some basic Congaree info here:
Be sure to purchase John Cely's excellent park habitat map at the Visitor Center to hone in on some of the better old-growth stands. Use caution when approaching the too abundant wild pigs that forage throughout the park as some of the old boars are humongous and able to inflict real pain. Birders working this area in March through June should always be aware of the very slight potential for Bachman's Warbler in areas of native cane and swampy blackberry and greenbriar thickets."

-- More of Same From Cornell --
--------------------------------------------------------------------------------------
Updates from Cornell have long taken on a tendency of divulging little new or encouraging information that was not already previously released. And such is unfortunately true of their preliminary report for the '06-07 season. Other than saying they will search further next year, very little in the way of encouragement here. Nothing positive to report thus far from all of the automatic cameras currently in place. A lot of emphasis continues to be put on the acoustic data ('kents' and double-knocks) --- as I've previously said, interesting but weak data upon which to build a case; certainly worth following up on, but, by itself, never diagnostic. Meanwhile, quite oddly, not a single team member sighting for the season is even mentioned in the report (do they regard none as credible?). Only the early season IBWO encounter claimed by a hunter in Wattensaw is briefly referenced. I assume their final report, whenever issued, will include several more details, but no greater weight of evidence.
Clearly, in addition to Arkansas' Big Woods, Cornell does find much habitat of interest and worth further study. Key searcher Martjan Lammertink concludes, “We are encouraged by the good habitat we have found. I’d like to spend more time in the Atchafalaya basin, in the Pascagoula in Mississippi, parts of South Carolina, and in the Escambia, Apalachicola, and other rivers of the Florida Panhandle” (all, places already known to be of interest). Lammertink mentions being "impressed with the sheer size of the Atchafalaya basin in Louisiana," and being "awed by the quality of the habitat" in the Congaree (S.C.) --- frankly, it's a bit disconcerting that Lammertink, who virtually proclaimed the Ivory-bill extinct in the 1990's and is considered an expert on the species, suddenly is impressed with habitats that were there all along and referenced frequently in the past for their IBWO potential. Where's he (and a lot of other folks) been all this time, and if his judgment was faulty in the 90's might it still be wrong? How many locales of interest were totally bypassed given his mobile team's limited time in the field? There continues to be no mention of central or south Florida, nor several other areas that may be worth a serious look-see. Instead, just continued emphasis on the Congaree, where I suspect Cornell/FWS may shift much of their attention next year.
Long ago I wrote I'd be amazed if an independent searcher accomplished what institution-based searchers, with their money, resources, and numbers, have failed to do (and document the Ivory-bill)... but... I'm beginning to wonder... In the meantime, other summary reports should be forthcoming through the summer. ------------------------------------------------------------------------------------

-- Watchin' and Waitin' --
--------------------------------------------------------------------------------------
...and waitin'... and waitin'...
Another search season ends with stiiiill NO evidence for the extinction of the Ivory-bill :-))) .... just further sightings claims and/or auditory encounters in at least 3 or more disparate locales. But for lack of a photograph many will choose to contend IBWOs must be extinct, not merely rare. Such contentions are easy to make, but when involving an entire species, rash indeed, while reports continue trickling in.
As I've said before (regarding false positives and false negatives, or, type I and type II errors), the most ill-consequential possibility in this situation is not in assuming a species lives only to realize later that it is extinct, but in assuming it's been extinct for 60 years only to then discover that it persists; a hugely serious blunder indeed.
... here, another photo of an Ivory-bill museum specimen I hadn't previously noticed:
http://www.flickr.com/photos/67388199@N00/397882868/ see ADDENDUM first!
ADDENDUM: THANKS!! (the internet is great) In case it wasn't clear to all, the reason I linked to this particular above photo was because of the peculiar lack of dorsal striping on this specimen --- didn't know if this could possibly result from the specific preparation techniques used, or if female IBWOs could be so variable as to not always clearly exhibit the dorsal striping, but thought someone seeing it might comment. Sure enough, the answer (which I didn't anticipate), sent in by a half dozen different folks so far, is that this is NOT an Ivory-billed Woodpecker afterall, but a MIS-labelled female Imperial Woodpecker. The incredible size of bill and feet probably could've been a tip off.

........................................................................
And for further entertainment here's one of my favorite old verbatim articles on the captive-bred/released California Condors; sure to bring a chuckle or two:
"Cocksure Condors" By Bob Saberhagen Californian correspondent
Filed: 09/09/1999"PINE MOUNTAIN — When former Sierra Club national chairman Les Reid helped....and not a lot has changed since 1999; see here:
pass the 1992 Condor Range and Rivers Act to provide habitat for the endangered
California condor, he never thought he would have them in his bed. Monday, while
working at the computer in the downstairs den of his rustic Pine Mountain home, the
84-year-old environmental activist heard noises coming from the top floor.
There Reid was greeted by eight giant California Condors cavorting in his bedroom.
They had ripped through the screen door leading from an outside deck of the hillside
home nearly 6,000 feet above sea level.
One bird was carrying Reid's underwear around in his mouth, he said.
"It was a beautiful moment," said Reid. "They just stood there looking at me.
They weren't afraid of this old white-haired gentleman." The group in Reid's bedroom
was part of a gang of 15 young birds that invaded the mountain community a week
ago and decided to stay. The 15 are among only 29 of the huge vultures flying free
in California, part of a recovering population that totals only 167 after nearly becoming extinct
in the 1980's.
Dubbed the "The Wrecking Crew" by biologists chasing them, the wandering birds have
spent the past few days making their presence well-known to residents of the mountain
community south of Bakersfield. But so far, to the dismay of some residents, a team of biologists
from the U.S. Fish and Wildlife Service's California Condor Recovery Program has been
unable to chase the endangered birds back to the wild.
While many locals marvel at their graceful daily flights over the village, others are not so pleased.
The giant vultures, averaging 20 pounds each with wingspans of 9 or more feet, have been soaring
from home to home at the higher elevations, startling several occupants with destructive, noisy —
and messy — visits to their decks and rooftops. Homeowners report the birds have destroyed patio
furniture, potted plants and insulated wires. They've also torn up roofing shingles while leaving huge
amounts of droppings in their destructive wake.
Recovery team members have been in hot pursuit, chucking pinecones at them when they land,
but the birds just flee from house to house. Their apparent lack of fear toward humans has Fish and
Wildlife biologists concerned for the safety of the group. The birds were born in captivity in San Diego
and released over the past three years in Lion Canyon near New Cuyama in northern Santa Barbara County.
"If they keep this up they could end up back in captivity," said biologist Mike Barth who, with team partner
Tom Williams, has spent the past several days trying to convince the birds to leave the area and shy away
from contact with humans. Pine Mountain resident Patti Fields resorted to squirting them with a garden
hose after they ignored her shouts, but they continue to return to her home each time biologists flush them
from another. "I just scrubbed the deck the day before they first showed up," she said, her nose wrinkled at
the mess on her roof and wooden deck. "They sound like an army marching across your roof."
The birds can drop a cup or more of excrement at a time, Williams said. While undesirable, the group's
behavior is not all that unusual. Condors have in the past been known to frequent areas populated by humans.
"It's normal for juveniles to hang out together and they have a tendency to tear things up," Williams said.
This group recently spent some time in the Stallion Springs area of Tehachapi, where Fish and Wildlife workers
are presently going door to door telling people not feed or encourage them. They have also visited homes near
Lake Cachuma. Recovery program officials said they are being tolerant — for now.
"We're hoping that when they start breeding they'll stop this kind of behavior," said Deputy Project
Coordinator Greg Austin. "We don't want to see these birds doing these things. Right now we're giving
them some slack." Austin said the birds, ranging in age from 2 to 5 years old, will reach sexual maturity
at age 6. Only 167 California condors are in existence today. They were near extinction in 1987 when
the last of 22 remaining wild birds were captured and placed in a captive breeding program. So far, 49
condors have been released to the wild since 1992, when the first 13 were released. Twenty of those are
presently in Arizona with the remaining 29 in California.
Ideally, biologists prefer the California-released birds remain within the 467,000 acres of habitat in
the Los Padres National Forest provided for them in the Condor Range and Rivers Act. Outside
the wilderness the birds face a host of urban dangers. Condors have died drinking anti-freeze, by
electrocution after landing on power poles, and others have become ill eating carrion containing lead
bullets. Many of the problems have been solved by using aversion training methods, including use
of mock power poles that jolt them with a low voltage shock. But this group of juveniles seems to have
forgotten lessons taught in the negative conditioning classes, especially the portion regarding fear of humans.
Among other perils they face here is the possibility they might collide with power lines during their low- level
flights through the community. "They can spread their wings and electrocute themselves," Barth said. Austin
said efforts to train the birds are being thwarted by well-meaning people who feed and encourage their presence.
Officials ask that residents stay at least 100 feet away from them. "If they approach, clap your hands and yell to
scare them off," said Williams. Above all, don't feed them, he stressed.
Williams said condors normally feed up to twice weekly on the carcasses of deer, cattle and other large, dead
animals found in the wilderness. Officers said they will continue attempts to persuade the birds to leave the
area where their activities will be constantly monitored. "We're going to keep tabs on them, document where
they go and what they're feeding on," Williams said. "We just want to keep them out of trouble," he added."

this is the well-known paradoxical 'game show' riddle of some years ago that many of you are likely familiar with (and which created a lot of controversy at the time); but if you're young enough or unmathematically-inclined enough, it might be new to you:
A game show host presents contestant Birder Bob with 3 doors, one of which has a brand-spanking new pair of Zeiss 10x42 FL T binoculars behind it, the other 2 have dead starlings -- the host KNOWS what is behind each door. Bob gets to pick a door and win the prize behind it (hopefully the binocs). The host asks Bob for his pick and he chooses door #3. The host, knowing where the starlings are, says I'll show you what's behind Door #1, and opens it, revealing a starling corpse. He then asks Bob if he would like to change his original door choice (to #2) or stick with #3, before revealing the prize. Should Bob switch, stick with his first choice, or does it make any difference (for his best odds of getting the binos)?

-- "Prime Season" --
---------------------------------------------------------------------------------------
With summer's full splendor of foliage, heat, bugs, and snakes, fast approaching, most official Ivory-bill searches for this season have concluded. Mike Collins however, says "prime season" for searching has just begun as he continues his efforts in the Pearl River region (LA.). I suspect by this Mike is referring to the fact that nesting IBWOs would've likely fledged by now and be moving around in family groups, calling to one another, and foraging often and widely for foodstuff (although he can speak for himself if he means something else).
The nesting period unfortunately is likely when IBWOs are hardest to stumble upon (most birds are), and without a knowing guide, like Tanner had, to lead them to a nest, today's searchers have been out-a-luck for photos. Pre-nesting, when pair-bonds are forming and territories established should also be a good time for searchers, and only the sheer scarcity of individual birds likely accounts for the rarity of sightings in those months.
Mike would likely abruptly re-write the approach to Ivory-bill searching if in fact he documented the birds during the humid months ahead.
........................................................................
This won't be for very many of you, but in honor of Mike being a mathematician, a couple of things:
If your interest runs to prime numbers, instead of prime search seasons, here's a website of interest with many links:
http://primes.utm.edu/
.... and now, a simple riddle (nothing to do with prime numbers):
"Three spiders named Mr. Eight, Mr. Nine, and Mr. Ten are crawling along a Louisiana swamp. One spider has 8 legs; one (mutant) spider has 9 legs; and one (mutant) spider has 10 legs. All of them are usually quite happy and get along amicably. Today however the heat is testing their patience.
"I think it is interesting," says Mr. Ten, "that none of us have the same number of legs that our names would suggest."
"Who the Hell cares?" replies the spider with 9 legs.
How many legs does Mr. Nine have?
[ the answer can be determined from the little information given, and there is only ONE correct answer? --- it's actually quite simple, but interesting how many folks have difficulty with it].

"Three spiders named Mr. Eight, Mr. Nine, and Mr. Ten are crawling along a Louisiana swamp. One spider has 8 legs; one (mutant) spider has 9 legs; and one (mutant) spider has 10 legs. All of them are usually quite happy and get along amicably. Today however the heat is testing their patience.
"I think it is interesting," says Mr. Ten, "that none of us have the same number of legs that our names would suggest."
"Who the Hell cares?" replies the spider with 9 legs.
How many legs does Mr. Nine have?
[ the answer can be determined from the little information given, and there is only ONE correct answer? --- it's actually quite simple, but interesting how many folks have difficulty with it].

Taking a cue from John Trapp at 'Birdstuff' Blog I took an online quiz to discover my "Power bird" and the result was interesting in several different respects I shan't explain:
(hmmmm... like that 'prophetic' part ; - )))
I suspect this may be whisking around the bird blogs in ensuing days....

Your Power Bird is an Owl
"You are beyond wise. You are so smart, you're almost prophetic.
Your inner voice always speaks the truth, and you take the time to listen to it.
You are good at seeing who people are... including the darkness of others.
As a result, you tend to have a rather dark -- yet realistic -- outlook on life."
(hmmmm... like that 'prophetic' part ; - )))
I suspect this may be whisking around the bird blogs in ensuing days....

--------------------------------------------------------------------------------------
Are we having fun yet!? ; - ) .... A lot of idle chatter in some IBWO Web quarters for the time being, but mostly just repetitive chaff, yada, yada... probably won't be much new to utter 'til reports/summaries arrive from USFWS, Cornell, Auburn, S.C. As in decades past, the clamor of skeptics, stifles info from being released in any ongoing or open manner, lest it get nitpicked to death prior to full analysis and review.
Be calm, patient, focussed, while ALL new info gets evaluated and let skeptical sorts blather on yada, yada. I suspect once reports/data are adequately reviewed there will be further study of the Congaree next season, as well as some Southeast areas that didn't receive much publicity this go-around, while some of this season's areas of focus will clearly be scaled back for next winter; but that's just a current surmise (and of course it all assumes no Ivory-bills revealed by automatic cameras prior to fall). Meanwhile independent searchers will continue to explore some of the locales that institutional searchers lack time/manpower for. A lot of unknowns remain, for the moment, unknowns, as the science slogs on, and we talking heads flap our lips and keyboards.

--------------------------------------------------------------------------------------
Well, screw the 3 days off ; - ))) ....
For a change-of-pace today I'll start with the Web Grab Bag first (Main Post follows after):
2 NOT-happy stories here, but the first one is interesting and instructional about the Condor restoration project, and the second one deals with some bird cruelty most of us were unaware of in the pigeon world (if you're especially sensitive to animal cruelty topics though I recommend skipping it!) :
1) http://www.signonsandiego.com/news/northcounty/20070524-9999-1mi24condor.html
2) http://www.reuters.com/article/domesticNews/idUSN2439565420070524
...finally, to offset those glum offerings, this verbatim parody of a Monty Python sketch, quoted recently by some chap over at BirdForum using the initials T. Allwood. I'd acknowledge the originator of it, but don't know who he/she be (... if you're not a M. Python fan you may want to pass on this, but I admit to being a bit of a sucker for John Cleese, or just a British accent really):
"Fitzcrow: ....I wish to complain about this woodpecker what I discovered not less than 2 years ago from this very big woods.
Skeptics: Oh yes, the, uh, the Pileated...What's,uh...What's wrong with it?
Fitzcrow: I'll tell you what's wrong with it, my lad. 'E's not the Pileated he's the IBWO and no one , seems to believe me.
Skeptics: No, no, 'e's uh,...he's a Pileated.
Fitzcrow: Look, matey, I know an IBWO when I see one, and I'm looking at 6 pixels of one right now.
Skeptic: No no he's not an IBWO, he's, he's a PIWO'! Remarkable bird, the PIWO, idn'it, ay? Beautiful bill!
Fitzcrow: The bill don't enter into it. It's all about the white trailing edge.
Skeptics: Nononono, no, no! 'E's an PIWO, you're looking at the underside of the wing!
Fitzcrow: All right then, if we're looking at the underside, then what about the white stripes on the back
(cut to Fitzcrow deinterlacing the video).
Skeptic: You just put those on during processing.
Fitzcrow: No I didn't.
Skeptics: Yes, you did!
Fitzcrow: I never, never did anything...
Skeptics: (yelling and examining the footage repeatedly) 'ELLO PIWO!!!!!
Now that's what I call a extinct species.
Fitzcrow: No, no.....No, 'e's hiding!
Skeptics: Hiding?!?
Fitzcrow: Yeah! Hiding, IBWOs hate man. They take on the appearance of a PIWO when ever a human looks at them for more than 3 seconds.
Skeptics: That's insane
Fitzcrow: Well, he's...he's, ah...probably pining for the swamps.
Skeptic: PININ' for the SWAMPS?!?!?!? What kind of talk is that?, look, why can't anyone photograph this bird, why can't we get video?
Fitzcrow: The IBWO's a magical bird. You must be in full ghillie suit and mask your scent to get but a glimpse. Remarkable bird, id'nit, squire? Lovely plumage!
Skeptic: Look, I took the liberty of examining the footage when I got it home, and I discovered the only reason that you think it's a IBWO is that you can't tell dorsal from ventral
(pause)
Fitzcrow: Well, if we admitted it was ambiguous we wouldn't have been given all these shiny new coins.
There are in fact many IBWOs from AR to LA.
Skeptic: "AR to LA"?!? Mate, this bird EXTINCT.
Fitzcrow: No no! 'E's pining!
Skeptic: 'E's not pinin'! 'E's passed on! This IBWO is no more! He has ceased to be! 'E's expired and gone to meet 'is maker!
'E's a stiff! Bereft of life, 'e rests in peace! If you hadn't deinterlaced the video 'e'd be pushing up the daisies!
'Is metabolic processes are now 'istory! 'E's off the twig!
'E's kicked the bucket, 'e's shuffled off 'is mortal coil, run down the curtain and joined the bleedin' choir invisibile!!
THIS IS AN EX-SPECIES!"
Crikey!!
..................................................................................
but seriously... Main Post:
We don't yet know exactly what the final summaries from S.C., Auburn, and especially Cornell will report for this search season, but due principally to the lack of a photograph, a lot of folks are expressing dismay over the search season (except for certain skeptics who can barely withhold their glee at the scarcity of results). So though I've covered this ground before, probably time to cover it again:
1) many folks continue acting as if the Ivory-bill debate began in 2004 with Cornell's announcement at the Big Woods... it began at least 50 years earlier. And for those 50 years no one seriously suggested that Ivory-bills resided along the Choctawhatchee, and only a few suggested the bird would be found in Arkansas (at the far north end of it's primary previous range). In short, even ZERO results from these 2 areas, not on the IBWO-radar pre-2004, would do nothing to debunk the prior 50 years worth of evidence from far more likelier river corridors of the deep south. It remains amazing how much certainty regarding a species' extinction is being expressed in some quarters for lack of an agreed photo from the few search areas systematically studied thus far, even while sightings however rare, continue to emanate therefrom. If only science were that simple.
2) Skeptics continue to overgeneralize from Tanner's small sample, or even from other S. American Campephilus species, or from the many clearcut cases of mistaken identification, or from a few locales, to all Ivory-bills and all claims and all locales; a commonplace but acute fallacy. The simple fact is that IBWOs continue to get reported by observers, and skeptics must explain why each and every one of those individuals is utterly wrong, a more difficult task than explaining why there is no photograph as yet of a scarce, rapidly-flying, cavity-dwelling species in a large expanse of land. When skeptics can demonstrate the intermittent lunacy of Terres, Garratt, Agey, Eastman, Dennis, Stoddard, Kulivan, Gallagher, Hicks, et.al. or when they can show that the Chipola, Fakahatchee, Suwannee, Altamaha, Escambia, Pascagoula, Wekiva, Mississippi, et.al. river systems have been adequately searched and no evidence of IBWOs discovered, THEN they'll have some real, instead of superficial, evidence for extinction. I'm willing to wait for that... or, other evidence, to arise.
In brief, in two short years (only partially devoted to searching) since the Cornell announcement, not much has changed (occasional sightings occur, interesting sounds, holes, and foraging signs are noted, and no photograph attained), but some skeptics are ever more strident in their disbelief of something for which they can't be certain (meanwhile it IS certain that some birders report seeing Ivory-bills). If skeptics are right, they have nothing to fear from further searches in appropriate areas, just more and more evidence will be gathered to support their case; so maybe what underlies their stridency is the one thing they do fear... that given enough time they'll be proven wrong (because, as they keep telling us, birders are sometimes mistaken).

-- Bird Life? --
--------------------------------------------------------------------------------------
Excuse my pessimism, but... :
BirdLife Int'l. now views 20+% of bird species worldwide as at "increased risk of extinction" --- What a bunch of starry-eyed optimists!! Such pronouncements often myopically gaze only a few human generations ahead. With the constantly accelerating rate of human-induced ecological changes, well over half of all bird species could easily be threatened just a few centuries into the future. Within 300 years, I'd wildly guess that the primary land-based bird groups in the United States might be Corvids, Psitticines(!), and Columbidae, and not much else (the outlook for water and oceanic birds may be even more dire). Conservation efforts are wonderful and to be applauded of course, but likely doomed in the loooong run, against relentless human forces; simply postponing the inevitable.
So why try to save Ivory-bills (or Whoopers or Condors or Kirtland Warblers or Red-cockadeds or... ) ? --- not so they'll be here 500 years from now (fat chance of that), but more simply because it is a right thing to do, and (a tad more self-servingly), no one wishes to say 'hey, they vanished on OUR watch'.
