-- And So It Goes… --
The latest issue of Birding Magazine from ABA includes a report from their official Checklist Committee, including the unsurprising decision that the Ivory-billed Woodpecker is not included on the current checklist, remaining instead a Code 6 bird, meaning probably or definitely extinct. The article is available in pdf form here:
Meanwhile, Cornell has uploaded a wonderful piece (~11 mins.) with Chris Saker and Martjan Lammertink on the use of a man-made "double-knocker" box to research the Pale-billed Woodpecker in Costa Rica. Although this was only uploaded recently I assume the design may be the same version(?) of the box that was employed during parts of the IBWO search in the southeast:
...would be good to know to what degree Cornell will make the boxes available to interested independent Ivory-bill searchers, or at least give out the specifications for folks who may wish to construct their own?
There are also some demo videos there of the exact same DK simulator design in use in Tennessee.
Anyone who deploys these should be aware, though, that if you have more than one party in the field, and one of the groups has a DK simulator, you will worry yourselves blue in the face trying to sort out whether any putative DKs heard by the other field parties were the simulator or a real-thing response to the simulator! Those spectrographic differences between simulated and real can help you sort this out, but only if you actually got a decent recording of the "unknown" DK. Even if you think you are certain about times, locations, etc., some nagging doubt will always remain.
