Whistling in the dark

Cornell has just posted this article called "Encounters in the Big Woods". Here's a paragraph (the bold font is mine):

According to Ron Rohrbaugh, director of the Ivory-billed Woodpecker Research Project, the search team uses a well-defined system for ranking any possible encounters. He says the latest visual encounters all rank in the lowest classification. "They’re all number ones. That means that no more than one field mark was observed, and it was observed by just one person,” he said. Although the visual and audio encounters may not constitute new confirmation of the presence of the Ivory-billed Woodpecker, Rohrbaugh agrees with Lammertink that these encounters keep the crew energized and the morale high.

Note that as of today, two full years have passed since Gene Sparling's claimed February 11, 2004 sighting. After a monumental amount of intense searching, not a single bit of evidence rises above the "false positive" noise that should be fully expected.
