WWNO just ran a long story on our search effort. You can listen at the link (recommended) and/or read the text. I’ll share some thoughts about it below, but first a brief update.
As April came to an end, Steve Latta, Jay Tischendorf, Tommy Michot, Phil Vanbergen, and I collected the AudioMoths that had been deployed in early March, completing the effort for the season. Jay, Tommy, and Mike Weeks will be returning to attempt some more DNA collection, and Tommy, Mike, and Phil will continue to service the trail cams. But the bulk of the work has come to an end.
We plan to get an earlier start next winter. And on the technical end, the lab is continuing to tweak the software and refine the machine learning; this has taken took a little longer than anticipated. Similarly, the DNA testing protocols are being refined. I don’t have a time frame for when detailed results will be available and can’t offer any information on if, when, and how results will be presented. But work is ongoing, and for next season, we hope that we’ll be able to turn the audio results around rapidly and get actionable information that will lead us to nesting or roosting sites.
To expand on something that’s mentioned near the end of the WWNO piece, I can say that I’ve cursorily reviewed perhaps .5% of the total audio, (from 3 or 4 of the first round deployments, February – early March). Most of this review involved scrolling through sonograms and listening when it seemed appropriate (meaning I likely missed a lot). It gave me greater appreciation for the technical challenges and the potential for false positives, especially when two or three potential confusion species are vocalizing simultaneously. While I have not heard extended bouts of kent-like calls at close range, I have heard more than enough suggestive sounds, both calls and double knocks, to be encouraged.
Changes to Project Coyote are in the works. Among these is a name change, to Project Principalis – to avoid confusion; I hope retaining “Project” will be enough of a reminder of Frank Wiley and the early days of our partnership. But there’s an existing NGO known as Project Coyote that focuses on actual coyotes, so the change is overdue.
It’s also likely that the blog will move to a different site and take on a somewhat different form. In the interim, there will probably be a guest post on Lazarus species by Jay Tischendorf, sometime in the next few weeks, and perhaps another one from me to detail the changes once they’re finalized. These plans are tentative at the moment. Stay tuned.
Hearing the WWNO story was a little disorienting. I’ve done a lot of media over the years, mostly unrelated to the ivorybill. I’ve never been the subject of such an in-depth profile. And I didn’t expect to be so much the focus. This is all about the ivorybill and the habitat, and while I won’t pretend to be above wanting acknowledgement for all my hard work, I am not the story.
I was disappointed that Phil Vanbergen and Matt Courtman, who made the March 2017 recordings and played a major part in bucking me up when my spirits were at their lowest, were not mentioned by name. I pushed for their inclusion as best I could.
Travis Lux, the reporter, first approached me about doing a story on Project Coyote back in 2015. He was just starting his career in radio and was planning to pitch the piece as a freelancer. Travis landed a job in Texas, continued to follow the blog but had otherwise been out of touch until he heard about the AudioMoth deployments, by which time he had returned to Louisiana. When he reached out to me in February, I think we both assumed that the focus of the story would be on the current effort. Apparently, the interest was there for a longer piece.
Listening to it was weird. I think it was the first time I’ve heard Frank’s voice since he died, at least in more than a very brief snippet. That jarring moment aside, four year seems like a lifetime. My thinking about the ivorybill and many of my perspectives have evolved since 2015. Today, I’d be a lot less excited about the bark scaling that’s a focus in the first part of the story than I was then. I’ve refined my scaling hypothesis considerably due to things I learned that year and later. I’ve also gotten more jaded, so I don’t think I’d be quite as overflowing with optimism.
The experience was a little like watching a movie based on a beloved book. The story wasn’t told in quite the way I would have liked; topics that seem important to me were glossed over; but I don’t see it through the eyes of an outsider. Taking that perspective as best I can, I think it was a well-constructed and illuminating piece. I hope you enjoy it too.
Here’s a gallery of photos from the recent trip.
Since we’re now involved in a formal scientific study, I will refrain from posting about possible encounters until the end of the season. Similarly, we will refrain from using attraction methods (playbacks, kent-imitations, ADKs) while the study is ongoing. We will have a steady presence in the area but will endeavor to tread lightly.
The work on deploying the AudioMoth units began on the evening of Thursday, February 7, with an instructional session led by Tessa Rhinehart of the Kitzes Lab. In the course of this session, we decided on protocols for the deployment period to insure that there’s no confusion about the data collected.
The next morning was training day. We set out to do our first round of deployments, with rotating groups of two learning the process. I was a little unnerved when it took us most of the day to hit eight deployment points. Fortunately, the pace picked up considerably over the course of the week.
On Saturday we broke up into teams of two. A journalist joined Steve Latta and me to observe and record the deployment process. This is someone who had interviewed Frank and me and spent time in the field with us a few years ago. News of the ARU deployment renewed his interest in the story, and if all goes well his report will be airing soon. Stay tuned.
Thanks to Tessa Rhinehart – for her clear instructions, for wrangling us all, for braving the challenging conditions. Thanks also to Steve Latta, Matt Courtman, Mike Weeks, Tommy Michot, Phil Vanbergen, and Patricia Johnson for all their efforts. We covered a lot of ground and worked hard to get the job done by mid-day Wednesday. Deployments are effectively completed for the season, with units to be swapped out for review. We have opted not to spread the recording units as thinly as we had originally planned.
I had one especially interesting find, a form of foraging sign I have only seen once before, in a cluster in 2015. It’s unusual, distinctive, and though it’s somewhat outside the category I’ve suggested may be diagnostic, I think it’s likely ivorybill work and have some hope we’ll be able to resolve that question once and for all.
I found a sweet gum limb standing, embedded in the ground. It had fallen recently, as dead leaves and balls were attached; the bark was very tight; and the wood was hard, showing no signs of rot. I found a small cluster of similar work in 2015 (scroll down in both linked posts), but this type of of feeding sign is extremely unusual for the area, and I’ve never seen it anywhere else.
In 2015, I was able to identify an invasive ambrosia beetle (a tiny Scolytid) as the source of the infestation. Sweet gum is one of the main host species, and infestation, which can kill limbs and saplings but not larger trees, has become increasingly common
The chunks of bark on the ground included the largest ones I’ve ever seen from a sweet gum, the one Steve is holding below, in particular. We have documented Pileateds removing bark from sweet gums, but never in pieces approaching this size or as extensively when bark is thick and tight. While this type of work is somewhat different from what I’ve hypothesized may be diagnostic for ivorybill, I suspect that IBWO is responsible for it. We’re hoping to be able to test the samples Steve collected for DNA, so stay tuned for that.
The only close-up of ivorybill excavation is in Tanner’s dissertation, showing some small holes in a hackberry. I see a similarity between that work and some of these digs.
I found one especially intriguing older cavity in a sweet gum snag this trip. The shape is unusual; it seems to be an expanded knothole. The same appears to have been true of the 1935 nest cavity. The fact that this cavity is surrounded by a scaled area makes it especially interesting, though it may well be disused.
Brief Update on Another Area
Before meeting up with the team on February 7th, I spent the morning of the 6th in the vicinity of the Saucier sighting. It seemed a fitting way to remember Frank, a year and a day after his passing. As has been the case in a number of prior visits, large cavities and bark scaling are easy to find, though the scaling was not as suggestive as the best examples from our main search area.
I’m planning another post related to trail cam deployments before long.
