ScienceNOW article

Here.

An excerpt (the bold font is mine):
Sibley says the new paper backs his argument: "He's documenting for the fist time how ivory-billed-like a pileated can be." But Fitzpatrick disagrees. He points out that the pileated woodpecker in Nolin's video quickly slows its wingbeats, as pileated woodpeckers are known to do. The bird in the Luneau video, in contrast, continues to fly rapidly for all 4 seconds. As for the plumage, he says that the Nolin video was not properly processed for frame-by-frame analysis. "The result is a blur and confusing to decide where the black and white are," he says.

Could this be the beginning of the unraveling?

If a pileated flaps its wings up and down like cardboard models as Fitzpatrick suggests and not in a rowing motion as “non-ornithologist” Davis Sibley suggest – where does all the white on Nolin’s video come from?

"where does all the white on Nolin’s video come from?"

All that white is not really white, its just a confusing blur waiting to turn black once its deinterlaced, or so we've been told.
