Project Coyote’s Future and Two Trip Reports from March

The audio obtained in March took precedence over the trip reports and a few other things I’ve been meaning to address for some time. They’re worth a listen if you haven’t done so already.

Longtime readers of the blog have probably noticed the donate button and the advertising that now appears on the site. Project Coyote has been mostly self-funded from the start, except for a few donations from anonymous individuals and the Rapides Wildlife Association. Some used equipment has been passed on to us by other groups of searchers. I’ve long believed that we’d be able to document ivorybill presence (or go a long way toward ruling it out) with more consistent coverage in the area and a relatively modest budget.

At this point, remote recording units and a couple of additional cameras are at the top of the wish list. Ultimately, I’d love to be able to cover costs for our core group and to provide funding for one or two people to be in the area steadily, at least during February, March, and April. I can dream . . . Anyway, your contributions can help make some of this possible.

Before Frank’s passing, I had decided to ‘retire’ from active searching after this season, for a number of reasons – the sense that I had nothing further to say about feeding sign and the fact that I did not personally see or hear anything strongly suggestive of ivorybill presence in the 2015-2016 season among them. The lack of recent work on hickories was particularly discouraging.

Things started to change when Frank was in the hospital. It became clear that our search was important not only to Frank but also to his family and friends. A number of long-time, mostly quiet, enthusiasts and supporters (including Matt Courtman who had visited the area with Frank some years ago) reached out and encouraged me to continue and even to intensify the effort.

Shortly thereafter, Phil Vanbergen found some recent scaling of the kind that I think is diagnostic for ivorybill on two hickories, though it turned out the work was not as fresh as initially suspected. The trail cam capture of a PIWO removing a strip of bark from one of the trees led me to begin my first March trip in a somewhat pessimistic frame of mind. It didn’t take long for that to change – another ride on what I’ve taken to calling the IBWO-llercoaster.

I arrived in the search area on March 9 and met up with two out-of-state birders with whom Frank and I had been corresponding for some time. I showed them around the search area. They were impressed by the habitat, but we did not see or hear anything significant. On the morning of the 10th, I sent an email to some of the team expressing my frustration over not having had a “compelling recent encounter” and stating that my possible October sighting didn’t meet that standard (even now, I don’t think it compares to the March recordings.)

I was on my own on the 10th and had a slightly less discouraging day; I got my first opportunity to examine the scaled hickories Phil had found. This strengthened my suspicion that the recent PIWO work was “wake feeding”.  Later, I met Matt for dinner and a strategy session.

Everything changed on the 11th. In addition to satisfying myself that the extensive scaling on the hickories was at least several months old and that the recent Pileated activity was likely secondary scaling (based primarily on the small bark chips); over the course of the day, we deployed three of our four trail cameras.


Even more importantly, we had auditory encounters in both the morning and the afternoon. Here is my write up from that day, with a few redactions.

At about 10:15, we were in close proximity to where we’ve had several possible contacts, most recently when I was out with Frank in October. We’d just deployed a second trail cam, and Matt had gone about 50 yards north and west of Phil and me. He texted and asked if he could do some DKs (he’s using two wooden blocks that he knocks together.) He did several, no particular pattern, mixed ASKs in with the ADKs.

I did not take notes, and my memory of the exact sequence is weak, but I heard 5-6 DKs and SKs coming from the east in response. If I remember correctly, there was at least some interplay between the ADKs and the DKs, meaning that there were a couple, and then a pause, then Matt DK’ed and there were replies. Matt said he heard 4-5, and I think Phil said he heard 3-4.

Whether or not I’m misremembering, it was far and away the most compelling series of responses I’ve ever heard, and I’ve done hundreds of ADK sessions. **** this was similar to what you encountered on your first trip, in the same general vicinity, but a lot more dramatic. In addition, there was no ambient foraging, and other than the responses, all we got was one PIWO drum from a different direction. Phil said that one of the DKs was very similar to the Pale-billed DKs he heard in Costa Rica last summer. 

For the kents, we were at a different location a few miles away; the time was approximately 2:45 pm. Phil and Matt heard a number of calls, of which I only heard two. Of the two I heard, the first was on the low-pitched side, I’d say close to the pitch of the what Tanner called “conversational” calls on the Singer Tract recordings or what Frank and I called the “wonka wonkas”; it had a trumpet-like quality, maybe more than I’d expect for an IBWO, but still in the ballpark. The second was higher pitched and more tooty/reedy, very close to the Singer Tract recordings. The wind was dead calm for the second call, so it was not a tree squeak. In both cases, the calls came from the East.

. . . 

So there we are. Quite a day. Now, if we could only find out what’s making the sounds and what’s knocking the bark off the hickories at the outset.

For those who missed it, here’s Phil’s recording of two of those calls – headphones or good speakers recommended. We did not record the knocks we heard in the morning.

On the 12th, Steve Pagans, Matt, and I returned to the location and heard 1 ambient DK and 2 SKs, at approximately 1:55 pm.

These sounds came from roughly the same direction as the calls we’d heard the day before. The possible DK was not as loud as the SKs, or as yesterday’s knocks, but it was distinct. Matt did some ADKs. There was a Red-bellied Woodpecker foraging to the south of the direction of the knocks. Matt’s ADKs seemed to induce it to bang more frequently and forcefully, but we didn’t hear any distinctly IBWO sounding knocks in response. Steve and I heard a single possible kent from the same direction as the possible SKs and DK. It was faint. Steve heard it better than I did and thought it was good; Matt didn’t hear it all. This was probably due to how we were positioned in terms of proximity to the sound.

Under normal circumstances I’d label this episode as a fairly weak possible, marginally worthy of mention on the blog. But given the location, it seems more significant.

The 13th was also eventful. Matt and I opted to return to the area where we’d heard the knocks on the morning of the 11th and give the other location a rest. Here’s my write up of the morning’s possible auditory encounter.

We decided to do a mix of playback and DKs at 9:40 AM. I did about a minute and a half of playback, using the iBird app (3 rounds – 28 seconds of Kents, “conversational” calls, and tapping). Matt followed with perhaps a minute of knocking wood blocks together. Over the course of the following five minutes, we had several knocks. Initially, Matt heard a single that I think I missed. It was followed by a very loud knock coming from the East. It was VERY loud and clear, what Frank would have described as some banging on a tree with a baseball bat. Shortly thereafter, another sound came from my left, roughly north of us. Matt heard it as a single, but I heard it as a double, with the second to my ears perhaps the closest thing to what Tanner described as an echo of the first I’ve ever heard. After that, we heard another loud single roughly from the southwest. The last was more distant and somewhat less striking.

The first single knock and the one I heard as a double were astonishing. There’s no doubt in my mind or his that these were neither mechanical sounds nor foraging. I am kicking myself hard for not having my recorder running; I’ve gotten too jaded about auditory encounters, and it’s a little tough to manage both recording and generating sounds.

A little later, I found a dying chestnut oak with some mildly intriguing feeding sign. There were some huge, thick bark chips on the ground and this, more than the appearance of the work on the tree, struck me as potentially suggestive; this is the first interesting work I’ve found on an oak in several years.

Matt and I returned to this location on the morning of the 14th. Matt did ADK series on the half hour until shortly before noon. It was a cold and windy morning, uncomfortably so. We heard nothing of interest.

On the 15th, I headed for New Orleans and my flight the following morning. Phil and Matt returned to the woods and captured numerous calls between 7 and 11 am. When I heard the recordings I cleared the decks and made arrangements to return as soon as I possibly could.

Patricia and I were back in the woods by lunchtime on the 23rd. Louis Shackleton – a good friend, professional photographer, and birder who happened to be in Louisiana – joined us on the 24th. We didn’t see or hear anything of interest and left early ahead of predicted heavy rains.

At shortly after 11:00 am on the 25th, Patricia and I heard some possible double knocks in apparent response to some very aggressive knocking on my part; two of these knocks came from roughly north and one from the east (the same direction from which the March 15th calls were coming).  I’m still reviewing the audio from this trip and may have additional material to post in the future.

I went out alone on the 26th, returning to the same vicinity, and did not see or hear anything interesting.

We were rained out on the 27th. On the 28th, I found a large cavity not far from where the calls were recorded. It does not appear to be fresh enough to be a recent nest, but we plan to target it with a trail cam in the event that it’s being used as a roost. This find illustrates how difficult it is to spot cavities in our search area – six people had spent the better part of multiple days in the immediate vicinity before I noticed it, and the snag is in plain view.

More storms came through on the night of the 28th, and the next morning Patricia and I decided to take a break from the “hot zone” and instead visited the area where Phil found the recently scaled hickories and where Matt, Phil, and I had heard knocks on the 11th and 13th. We found that one of Phil’s scaled hickories had lost its top, which gave me a chance to examine one of the scaled areas up close. As expected, the wood was somewhat punky, and and the bark was fairly easy to remove by hand.


We also discovered that the top of one of our target hickories had been blown off. The tree shows signs of beetle infestation, which gives us reason to hope that it will be visited by woodpeckers before too long.

It was interesting to get a close look at this freshly fallen top and examine how hickory bark separates from the trunk under these circumstances. While it seems to come free fairly easily in very large strips, the bark is extraordinarily tough and strong. When fresh, it’s flexible but very hard to break; doing so requires twisting, and it won’t fracture. Within about 48 hours the piece I collected had dried out and become surprisingly hard. This further reinforced my view that Pileated Woodpeckers are not anatomically equipped to scale large chunks of bark from live or freshly dead hickories.

It was a beautiful day in the woods, and some of the other highlights included recently hatched Wood Ducklings, a posing Yellow-crowned Night Heron, and the first ‘gator (a small one) I’ve ever seen in the area.

The next morning, I returned and redeployed a second camera, which had been trained on another nearby hickory, to the one with the downed top so that we can cover the entire stub.

We spent the morning of the 31st in the area where the calls were recorded before catching an afternoon flight. We did not note any interesting sounds while in the field, but after listening through Patricia’s recordings, I noted the possible double knock discussed in the previous post.

I’m planning two more trips before summer. I anticipate that we’ll have all cams deployed and have high hopes for the hickory stub.

Meanwhile, I thought I’d throw in some additional images that may help to convey what a special and magnificent place this is.
