		<description>Josh, The scientific community has considered all of the recent evidence objectively and fairly, and found it inconclusive. You obviously don&#039;t like that result, but you can&#039;t blame the scientists. There is nothing more to say unless new evidence comes along.</description>

		<description>What disturbs me about this whole debate is not the fact that the scientific community has declared the bird extinct, but rather the fact that &quot;Science&quot; is too proud to accept and consider reasonable evidence that the birds still exist. It seems as if many of the so-called experts are almost unhappy that there is a chance the birds are still around. One would think that bird enthusiasts would be willing to admit that they were wrong if it meant the rediscovery of a species though to be extinct. Perhaps the real issue is that most of the evidence produced has been by members of the common horde and therefore unacceptable to the scholarly pillars of the scientific community.</description>

		<description>I was not criticizing David Luneau. He had a video, and presented it to the team. The fundamental problem is that nobody put on the brakes. Then they ended up at the press conference a year later telling hundreds of reporters that this is &quot;rock-solid proof&quot;. Your comparison to the Sasquatch film shows that from the very beginning you knew it would never be &quot;rock-solid proof&quot;, so the announcement should have been &quot;We have reason to believe that there are still Ivory-billed Woodpeckers in Arkansas, and we will continue searching&quot;. The scientists on the team should have known that. Imagine how much of this fiasco could have been avoided if the initial announcement had been more realistic. Ultimately that was Fitzpatrick&#039;s responsibility, but he decided to go with the overblown media hype that has brought us to this point.</description>

		<description>As one of the very early members of the search team, I have a very different perspective. I was contacted by the Lab and employed by the Lab. My profession is wildlife film-making. I document species for a living you might say.

In reference to the Luneau video, we first saw this in May of 2004, in Little Rock, Arkansas. While there was excitement about the video, David Luneau was balanced in his presentation. There were many technical problems, but none more than the fact that his camera was on on autofocus.

I recall clearly walking up to DAvid, shaking his hand and saying&quot;Congratulations, you got the bird but unfortunately, the video you&#039;ve shot will never be more than the Sasquatch film.&quot;

How prophetic those words have become.
Sincerely,

		<description>Mr. Sibley,

Not sure if this is still read by you. My 14 year old son and I just returned from a 20 day birding expedition to Florida, where he evidenced many of the traits you write and debate about in these blogs-- too-quick ID, desire to see rare birds, etc. We still managed to get about 30 new spp. for him, and it was a great trip. And I served as the &quot;straight man birder&quot; on the trip. He has a thrill for the Ivorybill. Anyway, being a teacher with some time off, I am reading about it today, reviewing the films more than I ever had, and reading comments. I see one line of logic that is not commented on that I might add for consideration.

If the Luneau film was of a (fairly common) Pileated, and subsequently more people are filming in the same habitat, then more similar films would be shot. Since this does not seem to be the case in the last six years, this logic would favor the (near extinct) Ivorybill as the bird in the Luneau film, all other lines of inquiry being as they are. 
With all respect, and as a lowly amateur birder with a life list of &lt; 400 spp., I see an Ivorybill jumping off a tree and flitting away in the film. I think the 8.7 wingbeats per second is key, as is the failure of duplicating the film in situ with other Pileateds (if this is so).

		<description>Who doesn&#039;t want to believe the IBW is here and surviving? Likewise, every December, I still want to believe in Santa and there are many confirmed sightings of him. Excellent point on the dangers of believing our past insatiable consumption policy is somehow promising and redeemable.  Thank you,  I appreciate the insight.  But honestly, when taxpayers are spending trillions to bail out banks, 27M seems like a really crappy gratuity.  Luxury or not, I hate the idea of pitting species against species, but perhaps that is the reality- ugh!</description>

		<description>Emupilot, re: sightings,&lt;br/&gt;&lt;br/&gt;Tyler Hicks does report seeing the white trailing edge as the bird flew, along with the pale bill and other features, but his sighting fails all of the other tests. He&#039;s not using binoculars, and he&#039;s distracted by pulling out a camera and trying to snap some pictures (but the autofocus fails), and it all happens in only a second or two! In such a brief and imperfect glimpse, any observer can grossly misinterpret the observation. There are lots of examples in birding that leave everyone, including the observers, shaking their heads and wondering how they could have been so wrong.</description>

		<description>This is a very good point however. I have the same feeling when I recall some exciting talks on the results of the Slender-billed Curlew expedition organized by different groups. All the team searched the breeding habitat of this mystery species based on some historical data and habitat description. What if that paper described just an extreme habitat of SBC and the regular breeding site is completely different.&lt;br/&gt;&lt;br/&gt;I think besides others, Mr. Sibley (David) would be the happiest if the existence of IBW would be proved without doubt.</description>

		<description>I&#039;m wondering what Mr. Sibley et al. think about Lester Short&#039;s hypothesis, that the Ivory-billed actually depended largely on mature, fire-maintained Longleaf and Slash Pine forests. Short, I think, based his conclusions largely on the preference of the Imperial Woodpecker and the Cuban Ivory-billed for pine forests. I&#039;ve not read the original papers, but to me, it makes a lot of sense--the IBWO declined sharply in the 1880&#039;s, the period when the Longleaf Pine forest was nearly wiped out. (See Lawrence Earley&#039;s &lt;i&gt;Looking for Longleaf&lt;/i&gt; on that.) Jerome Jackson just alludes to this in his &lt;a HREF=&quot;http://bna.birds.cornell.edu/BNA/demo/account/Ivory-billed_Woodpecker/HABITAT.html&quot; REL=&quot;nofollow&quot;&gt;Birds of North America&lt;/a&gt; account--he quotes an author from the 19th century about how the bird was &quot;once a bird of uplands&quot;, and that would have meant Longleaf and Slash Pine forests.&lt;br/&gt;&lt;br/&gt;Under this hypothesis, the bottomland forest populations of Ivory-billed woodpeckers, such as that studied by Tanner, would have been remnants in sub-optimal habitat, and were probably doomed. And this would also mean that pretty much everyone has the wrong idea about Ivory-billed habitat today, both in searching and in conservation.&lt;br/&gt;&lt;br/&gt;I think that sort of question, probably never to be resolved, does emphasize just how little was actually known about the bird, and just how wrong-headed the current FWS recovery plan is.</description>

		<description>David, it is always a worthwhile discussion to decide if $27 million could better be spent elsewhere, but you shouldn&#039;t have to use a fabrication to make your case.  Your statement, &quot;All sightings emphasize a single field mark - the white trailing edge of the wing.&quot; is patently untrue as you ought to already be aware.  &lt;br/&gt;&lt;br/&gt;Cornell&#039;s &lt;a HREF=&quot;http://www.birds.cornell.edu/ivory/evidence/sevenSightings&quot; REL=&quot;nofollow&quot;&gt;seven sightings&lt;/a&gt; include descriptions of &quot;a narrow red crescent on the bird&#039;s folded crest&quot;, &quot;a small flash of red on the bird&#039;s black crest&quot;, and &quot;long neck with white stripe, and black head with long bill&quot;.  &lt;br/&gt;&lt;br/&gt;Tyler Hicks&#039; &lt;a HREF=&quot;http://www.auburn.edu/academic/science_math/cosam/departments/biology/faculty/webpages/hill/ivorybill/Updates.html&quot; REL=&quot;nofollow&quot;&gt;sighting of 12/24/06&lt;/a&gt; was of a perched bird at 40 feet away.
