Singer Tract Area Ivorybills in 1948

Just over a year ago, I quoted at length from a 1949 letter to Tanner from Arthur MacMurray (a former student).  I’m reposting that transcript below and have some additional commentary. Eckelberry’s famous “last” John’s Bayou sighting in April 1944 has become a legend, even though Peterson, writing in 1948, had the lone female remaining at John’s Bayou until December 1946.

John’s Bayou aside, the MacMurray letter suggests that at least three ivorybills remained in the vicinity of the Singer Tract until the end of 1948, although not in the areas that Tanner studied. I read these reports as involving at least three birds because Willett mentioned a pair, whereas Williams and McCallip involve a lone bird. The Williams and Willett reports seem highly credible to me, given that Willett undoubtedly knew ivorybills and MacMurray seems to have trusted Williams’s ability to recognize the species.

I have tried to identify the locations involved. Little Fork Road still exists, south of Little Fork Bayou. It is west of the Tensas, about 10 miles northwest of John’s Bayou. North Lake #1 presented a challenge. The only North Lake I could find in the area is the North Lake Marydale Oilfield, which is in Tensas Parish, about 18 miles south-southwest of John’s Bayou and 20 miles south of Little Fork Road, just outside what is now Buckhorn Wildlife Management Area. While it’s possible that MacMurray (via Willett) was referring to a designation on a lumber company map (H. Baldwin, pers. comm.), it seems reasonable to infer that this is the North Lake referenced in the letter.

It may be worth noting that as of 1943, a number of relatively small parcels in the vicinity of Little Fork Bayou, including the McCallip property, were not owned by Chicago Mill or Singer. Perhaps these parcels provided at least a temporary refuge, MacMurray’s reference to all he saw having been cut over notwithstanding. Perhaps this hints at how the remaining Singer Tract birds were dispersing or surviving in degraded habitat. Beyond that, there may be little to infer, except that while Eckelberry and the Fought boys’ “last sighting” was valid and makes for a moving story, its lastness is folklore.

***********************************************************************************

The Singer Tract has been cleaned of all its commercial timber as far as I could gather. No Ivorybills have been seen at John’s Bayou for at least three years, according to a resident who has lived adjacent to it for twenty-two years. ( . . . but he is on the lookout for them and remembers you.) John’s Bayou has a lumber railway passing thru it and passing all the way north to some point due west of Tallullah. The Ivorybills apparently left John’s Bayou soon after the large gum tree which had been their nest tree for several years was lumbered.

Mr. Gus Willett is still the local game warden. I phoned him. He expresses his best regards to you. He says that only one pair of Ivorybills are known to be in the region (seen in late November), having moved to North Lake #1. He says that whatever Ivorybills are left are apparently wandering over much larger areas than formerly. He says that all the old stands of gum tree are being lumbered now or very soon, so he thinks the prognosis for Ivorybills is dark and apt to be very brief. He doesn’t know whether or not Ivorybills have been found elsewhere in Louisiana or elsewhere in Florida in the past few years.

A friend of the gentleman who resides adjacent to John’s Bayou reported that he saw what he thought was an Ivorybill on E.C. McCallip’s property on the Little Fork Road 6 miles south of Waverly on December 17th of 1948. So Dot and I spent the night in Tallullah and visited McCallip’s place (minus boots – It was very muddy) All the land we saw looked cut over. There were lots of woodpeckers. Saw 5 Pileateds but none of their cousins. I questioned Mr. Ward Williams (address: Del Hi, Route 1, Box 184-A, Madison Parish, Louisiana) who recognizes Ivorybills and distinguishes between them and the “native” (pileated) peckerwoods. He claims to have seen an Ivory Bill there in November. He regards them as nesting residents and thinks he can find a nest of them there without very much hunting. I left my address, and he intends to write next time he sees a bird. He and his visitors were aware of Ivorybills having been at the Sharkey place adjacent (or in) to Singer Tract.

Dot and I found it expedient under the murky circumstances to proceed on to New Orleans for Xmas day.

. . .

Wish I had more optimistic new regarding the what kind of future we dealt the big-woods peckerwood.

Best Regards,

Arthur

Trip Report: April 26-May 1, 2017

I returned to the search area last week and spent as much time as I could in the field. The trip was generally uneventful, and conditions – strong winds, rain, and high water – limited my field time. Woodpeckers are getting quieter generally; full leaf out, heat (temperatures in the high 80s on the 26th, 27th, and 28th), and abundant mosquitoes make things even more difficult at this time of year; nevertheless, I’m planning one more trip before summer.

On the 26th, I hiked to hickory stub that currently has two cameras trained on it, as one camera needed securing. There were no signs of woodpecker activity on the stub. This beautiful Great Egret in a beautiful spot was a highlight. There were Little Blue Herons in the vicinity too, but I couldn’t get a clear shot, too much mud and intervening vegetation.

On the 27th, I arrived at the “listening point” (where the March recordings were made) shortly after sunrise. I opted to sit quietly, rather than doing playback or ADKs. I did not see or hear anything.

I met up with Steve Pagans at around 10 am. Since water levels were low, we were able to get closer to the snag with the cavity that I found last month. I spotted a second cavity higher on the stub, on the opposite side. IMGP4571 (1)

These cavities are large, similar in size, shape, and unusual appearance. While I suspect they are no longer active roosts, we will put a camera on the snag in June, if it’s feasible to do so. The nest John Dennis found in Cuba appeared to have two entrance holes, although Dennis thought one might be too small.

On the hike out, I spotted this wolf spider with her young on her back.

On the 29th, Steve and I visited one of the less accessible parts of the search area. It is an impressive patch of forest, with some oaks and sweet gums approaching or surpassing 5′ DBH. The sweet gum below is probably the largest single trunked gum we’ve found.

Reminiscent of the Singer Tract.

Predicted wind speeds were 15-20 mph, and the gusts were undoubtedly stronger, so birds were not very active. The gusts were often unnerving, and a couple of large limbs fell, uncomfortably close to us, while we were stopped for lunch.

The forecast for the 30th was for even stronger winds, with thunderstorms in the afternoon. We decided to play it safe and stay out of the woods. Steve went home, and I spent part of the day driving scouting a large patch of nearby forest by car, but I wasn’t able to reach the bottomland area that had intrigued me on Google Earth.

The rains didn’t arrive until evening, but they were very heavy, with 3-4″ overnight. Thunderstorms continued until mid-morning on the 1st, so I didn’t venture out until about 10:30. Conditions were cool and cloudy, and everything was soaking wet. My movements were limited by high water levels; these continued to rise during the four hours I spent in the field. Avian activity was again minimal. Coming across this rattlesnake, the third or fourth I’ve found over the years, was the day’s highlight.

On May 2nd, my last field day, I spent the early morning trying to get to the hickory stub and trail cams. Water levels were too high, so I returned to my car and drove to a more accessible location. While I have been concentrating on it less this season, there have been a number of possible contacts in this area, and we have found abundant sweet gum scaling there every year. As has been discussed in several recent posts, classic, ‘Tanneresque’ high branch scaling on freshly dead sweet gums is not necessarily inconsistent with Pileated Woodpecker.

Still, I found some very dramatic work on the dead fork of a dying gum. Phil and I first found this tree in February, but most of the scaling has taken place since then. Of particular note were the enormous bark chips found at the base, again all removed since the end of January. My hat, which is shown for scale, is 12.5″ x 12″. Note that this scaling involves some of the largest limbs. Since some gum balls are still attached to the dead limbs, I think it’s safe to assume that the bark remains relatively tight; the scaling also looks generally clean, something that I find suggestive of ivorybill. To the best of my recollection, the bark chips are the largest I’ve ever found from sweet gum limbs.

Later that morning, I found a mildly intriguing cavity in a small sweet gum (~18″ DBH). While it’s almost surely PIWO, I’m including it because the shape and skewed angle are somewhat interesting and also to illustrate that even smaller trees can host substantial cavities. The original image was badly backlit, so I’ve brightened it and rendered it in black and white to make the cavity easier to see. Referencing Dennis again, he estimated the diameter of his Cuban nest tree at 12″. While DNA evidence suggests the Cuban IBWO is/was a different species, more closely related to the Imperial than to the US IBWO, the conditions under which Dennis found a breeding pair seem relevant to the survival of the North American species, and the ‘old growth specialist’ caricature:

There was a sprinkling of deciduous trees, some quite large. Although this region had been heavily logged and burned over as well, growth was quite luxuriant in spots. A watercourse, as well as the generally rugged terrain, had prevented a clean sweep of all the timber. The pine  trees, on the whole, were limited to less than five inches in diameter.

There may be more on this in an upcoming post.
