So, David Luneau just posted to the Arkansas list that the "astounding" and "conclusive" sound recordings referred to in recent news articles may not be recordings of Ivory-billed Woodpeckers! This is starting to get interesting again:
The sound recordings that have been referred to in recent news reports are still being analyzed. It is premature to assume that they are recordings of IBWOs as reported in the press, as that conclusion has not been reached by everyone involved. There will be a presentation on the results (to date) of the acoustic data given by Russ Charif of Cornell at the AOU meeting in late August. As of now, none of the recordings are available to the public.
