Frank Wiley Hospitalized

Two weeks ago, Frank went into the hospital. About two days after admission, he was taken to the ICU with a systemic infection. He started showing signs of improvement on Monday this week and was able to go off the ventilator as of yesterday. (I was there from Tuesday 1/24-Tuesday 1/31.) I know Frank to be a fighter, but even so, he’s doing far better than I expected. His family is asking for prayers, so if that’s something you do, it would be appreciated. My thoughts are with him and with them.

Recordings from January 2010

When I began blogging on WordPress, I mentioned that I’d be posting sound clips from our old search area that were available on the old Project Coyote site, but I’ve been somewhat undecided about it and wasn’t sure I could track down all the material, a problem I’ve now solved. The most interesting audio was obtained between January 24-26, 2010. Archived selections from those recordings and accompanying sonograms are available through the Wayback Machine, and you can click on the links to hear the clips. Some of these were recorded in the field on handheld devices, while others came from remote units provided by Mark Gahler.

In addition, to these selections, I thought I’d take the opportunity to post Frank Wiley’s entire recording of the extended auditory encounter that took place just after noon on January 25th so that readers can hear the full recording as well as the extracts. Six people were present when this incident occurred, and it’s unusual in recent IBWO history, not only for the number of people present but also because putative double knocks and kent calls were heard during a single event that appeared to involve at least two birds. See below for a little more about the old search area, how we got there, and what transpired between Summer 2009 and January 2010. This is the same area where we obtained the suggestive camera trap photos. The adjoining parcel was logged between November 2010 and January 2011, and there has been little indication that IBWOs may be present since that time, although we suspect they may still be using one or more of the nearby Wildlife Management Areas. Frank’s complete 58 minute field recording should be of interest to the dedicated among you. If you’re wearing headphones, note that there are some clarinet toots at the beginning; a possible kent call follows soon thereafter:

The search effort was inspired by what seemed to be a credible report from a resident of rural East-Central Louisiana. This individual, who passed away shortly after Frank Wiley arrived on the scene, had attempted to report sightings of ivorybills for a number of years but had been dismissed. When Frank interviewed him, he was not only insistent that birds were present in the area, he corrected the drawings that are included in the Louisiana Game Guide.

The red shapes at the upper right are his rendition of the difference in shape between and ivorybill and pileated wings. He showed the crest as somewhat more erect in flight and perched. Perhaps most significant, he accurately depicted the female crest as considerably more erect than the game guide’s version (the red pen was used to highlight the differences not to show color.) I did not have the privilege of speaking to him, but Frank Wiley has told me he was very emphatic about these corrections.

During almost weekly visits to the property and surrounding locations between August and November 2009, Frank had several possible sightings, one of which involved three birds. In two instances, he obtained photographs, but these are of birds in flight at some distance and do not show definitive field marks. In addition, he heard suggestive knocks and kent calls on numerous occasions and recorded a number of the knocks.

I made my first visit to the location in November, 2009 On November 24th, 2010, during a stakeout of the location where the first of these photographs was obtained, we heard but did not record an extended series of calls, lasting approximately ten seconds, and coming from the general vicinity of the sighting described below. These calls were unlike others that have been recorded by contemporary searchers and resembled those documented by Tanner and Allen at 03:14 on the Singer Tract recordings.

On November 25, 2009, Frank and I were staking out a feeding tree when a large woodpecker flew into the top of nearby pecan. The bird was obscured by foliage but was moving around in the canopy as I tried to observe it. Frank moved and flushed the bird, and I got a brief glimpse as it fled, but only enough to notice white on the wings that appeared to be too extensive for a pileated. What was perhaps more significant about this sighting is that we both heard loud, rapid, Wood Duck-like wing beats, at a distance of approximately seventy-five feet. Later that day, I  flushed a pileated at much closer range and the wingbeats were considerably softer and muffled sounding. We placed a camera trap in this location and the second image on this page was obtained there a week later.

Between January 24-26, 2010, Bill Benish, Ross Everett, and Frank Wiley had possible sightings. Everett, McCaslin, and I heard possible kents on the morning of January 25, and shortly after noon on that day, all six participants had an extended auditory encounter that was recorded in part by Wiley, Benish, and me on separate recording devices; a couple of minutes had elapsed before team members were able to activate their recorders. All team members heard multiple kents and double knocks during this incident. We believe that two birds responded to the banging of a tin roof on a deer stand in the vicinity. Just before sunset on January 26, Benish heard and recorded a double knock. In addition, Mark Gahler’s remote recording devices captured possible kent calls on January 25th and 26th.


Encounter Rate

      A poster on the Ivory-billed Woodpeckerl Researchers Forum raised a couple of questions about sightings and their quality, and about our encounter rate. I thought I’d take this opportunity to respond here.
      A number of people have had possible sightings in this area. Quality is a subjective term, but it’s safe to say the quality has varied. In most cases, the sightings have been by single observers. A few have involved perched birds. Distinctive features – black crests, malar and dorsal stripes and bills – have been noted in several instances; however, most have been fleeting glimpses of birds in flight. One recent flyover may have involved a pair – field marks were seen on one of the two birds. Just as we see little point in posting additional audio unless conclusive documentation is obtained, we don’t think that posting details of sightings serves much purpose, unless it’s a robust, two-person observation or is accompanied by a clear photograph.
      A little background on the encounter rate. I made my first search trip to Arkansas back in April 2007. Since then I have spent countless days in the field, probably upwards of 100 by now, in Arkansas, South Carolina, Florida, and Louisiana. I’ve learned a lot over the years; I’ve made some mistakes; I’ve written off some possible encounters as wishful thinking and have tried to maintain a healthy self-skepticism. I’ve also been somewhat obsessed with finding a category of feeding sign that is beyond the physical capacity of a Pileated Woodpecker to produce and is therefore diagnostic. As discussed in some of the recent posts, I believe I have succeeded in this, but of course my belief remains just that and is entirely unproven.
      While we don’t count finding suggestive foraging sign in estimating the ‘encounter rate’, which is actually a possible or putative encounter rate, the quantity of scaling that I consider to be Grade A or that is congruent with Tanner’s description far surpasses what I have seen anywhere else. Our old search area was considerably more compact, and in 2009 and 2010, before the adjacent parcel was logged, it was fairly easy to find suggestive feeding sign within that compact area. Since that time, I’ve refined my criteria for Grade A scaling and have made them somewhat more stringent. Nevertheless, this year in the new search area, I have found sign that meets my criteria or fits the Tanner model on virtually every field day. During trips last year, fresh scaling seemed to have been concentrated in one or two locations, and this year it seems to be more scattered. This is purely impressionistic, but whatever the case, there is an abundance of feeding sign that is unmatched by anything I’ve seen elsewhere. And I have never seen scaling that resembles what’s shown in my May, July, and October posts anywhere else, save in the former Project Coyote search area.
      Regarding the encounter rate itself: we include all putative encounters – DKs, whether ambient or in response to ADKs, putative kents, and possible sightings – even weak possibles. We estimate that we have been having one putative encounter for every 20-24 person hours in the field. The rate was considerably higher on my recent trip but probably nowhere near high enough to change the estimate. I should also add that, purely impressionistically, this is the only location where I have heard frequent apparent responses to ADKs. We had a possible attraction in the old search area and did get apparent response DKs from time to time, but nowhere near as often as in the new search area.
      The challenge lies in figuring out where the birds are roosting and nesting, if indeed they are present. We suspect there may be a nesting pair, as auditory encounters in the southern sector have frequently involved two sources of sound. To date, we have no indication that more than one bird is present in the northern sector. We have had very little success finding cavities in either sector, but it has also been difficult to find Pileated Woodpecker roosts in the deeper parts of the swamp, even in obvious, defended home ranges.
      I will be making brief trips in November and December and probably a somewhat longer one in January.

About Project Coyote

In 2009, we  learned of a private landowner in East-central Louisiana who claimed to have Ivory-billed Woodpeckers on his property. This individual seemed to be very credible, correctly pointing out several inaccuracies in sketches published in the Louisiana Hunting Guide. Over the next two years, there were a number of  possible sightings and auditory contacts. Frank Wiley, Mark Michaels, and other Project Coyote volunteers gathered evidence – camera trap photosgraphs, recordings of  suggestive calls and double knocks, images of extensive bark scaling on living and recently dead trees in the vicinity. This material was originally posted on a website that is no longer operational. We have received a number of requests to revive the site and have decided to do so here. Pages that included images will be available in PDF format.

In 2011, a large parcel of adjacent forest was logged, and while we believe that ivorybills are still present in the vicinity of the original Project Coyote search area, the birds do not seem to be frequenting our old hot zone. For this reason, we have shifted our focus to other parts of the state. We remain optimistic that the species is present in multiple Louisiana locations and that conclusive documentation will eventually be obtained, but this may well take years.
