Source: ARU cuts are likely Blue Jay calls

I have learned from an anonymous source that the Automatic Recording Unit (ARU) cuts trumpeted as being a good match for an Ivory-billed Woodpecker (and reported as such in a letter to Science in early September) are more likely of Blue Jays. Moreover, the sound collection at Cornell has several cuts of Blue Jays that seem to match, or at least account for, the sounds recorded on the ARUs.

Although in their own collection, it appears that these Blue Jay cuts were not examined before the Cornell team sent their latest offering to Science. Rumor has it that the Cornell team has since analyzed these Blue Jay cuts and acknowledged that they are a good match.
