-- More Retrospective --

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

Mark Michaels has newly-posted a retrospective of Ivory-bill sightings (and other info/commentary) from 1944 - 2003 at the Project Coyote site:

Nice job Mark. Makes for a good adjunct-read to Chuck Hunter's historical review of the evidence in Appendix E of the "Recovery Plan For the Ivory-billed Woodpecker" from USFWS (starting on pg. 66):

And I agree with most of Mark's points, especially regarding scantiness of valid information, certain flawed analyses and assumptions, and the circularity of various arguments (though he's probably more favorably-disposed towards certain bits of evidence than I am). The bottom line for me still remains:
There have been a significant, even if rare, number of sightings over time (not always highly-publicized) from individuals (birders, wildlife officers, park rangers, etc.) who should be able to reliably recognize an IBWO apart from similar species. To which skeptics will frustratedly opine, "Yeah, yeah, yeah, so get a #$%@*^%!!! photo!" ...and I DO sympathize with them and several of their arguments. But the possible habitat of the IBWO is remote, dense, and neither visited by birders in great numbers nor with great frequency. My only excuse for the lack of a definitive photo by now, even when areas producing credible claims are scoured, is, as previously noted, the combination of the species' sparseness with a lifestyle, I think, spent mostly in the upper tree canopies, out of easy or good view.  So while hope fades, it is far from gone. And while I wish I had enough faith in the practice of science to draw a conclusion of extinction based on the evidence so far collected... I don't.
