-- Springtime Updates --

------------------------------------------------------------

Mark Michaels has a new post up for their Louisiana search, including more details on methods/criteria being employed, and a further mention of the attempt to attain analyzable DNA from scaled bark.
They have swapped out their first set of audio recording devices… he mentions, but doesn’t go into detail, obtaining “preliminary results” from the deployments, so I’m not sure if that means all audio has been reviewed already or more likely is still underway? I imagine another post for specific putative audio findings will come later.


And Jackson Roe, at his blog (in Arkansas), also recently entered another post wherein he speculates about the suitability of Western Cuba for IBWOs.

Thanks for the mention and the link. Some of your characterizations may be confusing to your readers, and I wanted to shed a little more light.

Results thus far are preliminary but encouraging. Much remains to be done on all levels. There are many thousands of hours still to be recorded, though many thousands have already gone through some analysis.

At this point, I can't comment on when and how findings will be made public. It's not my decision to make.

Regarding the DNA collection, the science on this is sound; it is fairly well-established at this point; and as with the remote audio, the technology has improved dramatically since the Auburn and Cornell searches of the aughts, or even five or so years ago.

To be clear, we are not trying to collect DNA "from scaled bark". We are trying to collect DNA from places where it's most likely to have been deposited - insect tunnels into the sapwood (more promising), the surface of scaled trunks (somewhat less promising), and from cavities (promising but with many complications).
