Cornell Daily Sun article

You should read this entire Cornell Daily Sun article on the Ivory-bill controversy.

Here's just one snippet:
The lab of ornithology has just designed a new website with a detailed analysis of the [Luneau] video that, according to Fitzpatrick, allows everyone to see what Cornell ornithologists take as proof of the existence of one ivory-billed. The website also allows viewers to compare the ivory-billed video with over 60 videos of pileated woodpeckers.

Sure would be nice if they would happen to tell the rest of the world where they have hidden this web page, eh?

http://www.birds.cornell.edu/ivory would be a good place to start. I find it interesting that in the video the canoe appears to do a pretty good dip, and then damps out the up-and-down motion immediately, but the passenger never seems to move.

There were two people in the canoe. Probably the other guy moved.

I have a slightly different take on the position of the bird in the video.

If you use the slider to slowly advance the video just prior to Frame 33.3 you can see the bird scoot to the left of the tree trunk. It looks to see what is approaching. It momentarilly provides a partial profile.The bird then turns right to launch itself.

I can just discern the white stripe below the crest and the nape stripe - "it's a bit of a stretch but I keep seeing it". The images of Ivory Bills that I've seen do not have the white stripe below the crest directly above the eye. Pileateds do though.

Frame 66.7 does show the birds' tail with its body totally obscured and the position of the bird is correctly identified.

Try to view the video with the positioning I described. The video is poor and the Normal Size setting is best. Work the slider slowly forward and back at that frame.

Please tell me if I'm wrong. Maybe I too only see what I want to see.

Phew, I have at least 20-20 vision but viewing this video will make me go blind I think. The shoring up of the video evidence probably means no new evidence and gettin' worried.
With this video, I never know what I'm seeing especially the peek around the
tree which I know is likely but
gimme more pixels. OK I'll watch
the dang thing again!
I can't wait to see the new website if I can trust what my eyes that is!

Can a Pileated Woodpeckers be pied?

If so were any observed with white in the following areas combined:

Lower coverts
Median coverts
Breast
Alula
Greater primary coverts

That is the bird in the video.

"you can see the bird scoot to the left of the tree trunk"

I don't see this. What I do see is some stationary feature on the tree trunk (another branch stub?) being revealed from behind another tree trunk in the foreground as the boat travels forward. The only evidently moving object I see in that area appears very briefly as the bird flushes, and is far too indistinct to make out what part of what bird it is.

"you can see the bird scoot to the left of the tree trunk"

Yes! The first view of the bird is it's wing{patch of white)Frame 33.3. If you pause the video at that point then use the slider to slowly advance the frame you'll see the bird peer out at the oncoming boat(Use the slider to slowly go back and forth at this point in the video). It then pivots to the right.The bird is now perpendicular to the tree trunk with only it's tail visible.

It then launches itself from the tree. It then flies out a bit,dips down slightly,turns left and flies away from the camera.

If you pause the video at several points after it launches from the tree you'll see the huge area of white on the wings. That doesn't look like the underside of a IBWO at all.

The "Normal" size setting on the player is best. "Smaller" is too small and the "Larger" setting is too pixelated.

Too bad the camera wasn't focused on that spot. But then again if Mr. Luneau had been holding it, I doubt the video would have been as steady.
