Sasquatch, rare woodpecker among strange Stennis tales

Wednesday, Oct. 26, 2011

By MICHAEL NEWSOM - mmnewsom@sunherald.com

Isolated within a sprawling buffer zone protected by highly secure entrances, the John C. Stennis Space Center is an easy target for paranormal stories.

The large site’s mystique has spawned some wild theories about what goes on inside it and its buffer zone -- 212 square miles of mostly wilderness and swamp. Stennis workers get some strange inquiries about what goes on there from those interested in UFOs and other topics, said Marco Giardino, NASA historian at Stennis.

“You get some strange phone calls that all NASA centers get,” Giardino said. “You know, people who wear aluminum-foil helmets or are being looked at by aliens. There are people who think we caused climatic change by landing on the moon. There are people who don’t think we landed on the moon. You get a cross-section of crazies that all NASA centers get.”

But despite the calls, there’s nothing odd going on there, Giardino said.

“We have a very vibrant tourist program,” Giardino said. “People get to come here on tour buses all the time. The mainstream public is pretty well aware of what we do, and none of it is sneaky or nefarious.”

Cajun Sasquatch?

The rocket-testing center is bordered by two large marshlands -- Honey Island Swamp and Devils Swamp. Some interesting tales have come from Honey Island Swamp, Giardino said.

Some believe the “Cajun Sasquatch” roams the Honey Island Swamp, which is on the western side of the Stennis buffer zone near the Louisiana state line. The creature is also known in south Louisiana lore as the “Honey Island Swamp Monster” or in some cases la bête noire, which is French for “the black beast.” The creature has been described as hairy, with fur colors ranging from orangey, black, grey or brown, in various news stories and television interviews dating as far back as the early 1970s. Some descriptions say it’s about 7 feet tall and weighs 400 pounds.

“(La bête noire) is what the Cajuns call their Bigfoot,” Giardino said. “Old Cajuns swear that it jumps on their flatboats and also leaves huge footprints.”

Giardino said Stennis officials don’t get as many calls about the beast as they did years ago.

There are other legends about something called the “loup garou,” which is French for werewolf, living in the nearby swamps of Louisiana

“It is such a massive wilderness that it has been identified as one of the potential places that bigfoot, or ‘la bête noire’ or the other mythical swamp beasts live,” Giardino said. “On its own, it’s really a place full of mystery, and still has bears and alligators and God knows what-all in it.”

Ivory-billed woodpecker?

In addition to menacing, mythical swamp beasts, there have also been reports of the elusive ivory-billed woodpecker living in the woods around Stennis, Giardino said. The scientific community has been at odds over the last several years about whether the large woodpecker, long thought to be extinct, has actually died out. There have been some sightings of the bird near the facility, as well as other areas across the southeastern United States.

In spring 2005, after various alleged witness accounts from across the country surfaced, along with a reported video of one of the birds taken by a University of Arkansas at Little Rock professor, some scientific groups declared the ivory-billed woodpecker wasn’t extinct. Others in the scientific community disputed that claim.

Giardino said there have been reports of the relatively large woodpecker, which has a wingspan of up to 3 feet, living in the buffer zone. It’s often confused, though, with its common, smaller cousin, the pileated woodpecker.

Whether there’s a Sasquatch, or the rarest of birds, living there, the sprawling marsh of Honey Island Swamp can capture the imagination, Giardino said.

“It’s huge,” Giardino said. “As you drive toward Louisiana, there is nothing but trees and waterways. It’s a really beautiful place, but I wouldn’t be there at night, bête noire or not.”

$50,000 Reward For Locating Live Ivory-billed Woodpecker

Ivory-Billed Woodpecker Sighted and Recorded

ScienceDaily (Apr. 29, 2011) — Dr. Michael Collins, Naval Research Laboratory scientist and bird watcher, has published an article titled "Putative audio recordings of the Ivory-billed Woodpecker (Campephilus principalis)" which appears in the March issue of the Journal of the Acoustical Society of America. The audio recordings were captured in two videos of birds with characteristics consistent with the Ivory-billed Woodpecker. This footage was obtained near the Pearl River in Louisiana, where there is a history of unconfirmed reports of this species. During five years of fieldwork, Collins had ten sightings and also heard the characteristic "kent" calls of this species on two occasions.

Scientists working independently in three states have now published articles that report multiple sightings of and various forms of evidence for this elusive species, which is extremely difficult to observe and photograph due to its rarity, wariness, and tendency to roam over wide areas in remote swamp habitat. The two previous articles present findings from Arkansas [Fitzpatrick et al., Science (2005)] and Florida [Hill et al., Avian Conservation and Ecology (2006)].

During two encounters with an Ivory-billed Woodpecker, Collins heard high-pitched calls that seem to match the description of an alarm call that was reported by James Tanner in the 1930s but was never recorded. On both occasions, the calls came from the direction of the bird and began at a moment when the bird was alarmed. Several of these calls were captured in the first video, which received a positive assessment from an independent expert, Julie Zickefoose, whose paintings of Ivory-billed Woodpeckers have appeared on the covers of a leading ornithology journal and the leading contemporary text on this species. According to Zickefoose, the large woodpecker in the video has a large crest, large bill, long neck, and rared-back posture consistent with an Ivory-billed Woodepecker, and it has ponderous and heavy flaps and takes an unusual flapping leap that is unlike anything she has seen from a Pileated Woodpecker (the only other large woodpecker in Louisiana).

The second video shows a bird in flight with flaps that are radically different from the duck-like flaps that were expected, but a long overlooked clue in a photo from 1939 suggests that there had been a misconception about the flap style. The combination of the flap style and the size rule out all species native to Louisiana other than the two large woodpeckers, but several characteristics rule out Pileated Woodpecker. This footage was obtained when an Ivory-billed Woodpecker flew along the bayou below a tall tree that was used as an observation platform, providing a view from an advantageous perspective of the white stripes on the back and the white patches on the wings. A little over a minute before the bird flew into view, the video captured a putative double knock that matches a putative double knock that was recorded by Hill et al. in Florida.

Collins began searching for Ivory-billed Woodpeckers in November 2005, shortly after Hurricane Katrina passed through the Pearl River. His first sighting was on February 2, 2006, and then two weeks later he discovered a "hot zone" a short distance up the same bayou, where he had five sightings (two of exceptional quality) and also heard the characteristic "kent" calls of this species on two occasions (once coming simultaneously from two directions) during a five-day period. The first video was obtained in the "hot zone" on February 20, 2006.

During the summer of 2007, Collins started climbing tall cypress trees to watch for Ivory-billed Woodpeckers flying over the treetops in the distance. The idea was to increase the encounter rate by opening up a larger field of view. Professor Steve Sillett, of Humboldt State University, and his colleagues, Jim Spickler and Michael Taylor, donated their expertise and time as well as a full set of gear for climbing trees. The approach provided results less than a year later, but not as expected. On March 29, 2008, an Ivory-billed Woodpecker flew directly beneath one of the observation trees, and Collins saw the definitive white stripes on the back and white trailing edges of the dorsal surfaces of the wings. Just over a minute before the bird flew into view, the camera recorded a putative double knock that is consistent with a putative double knock that was recorded in Florida.

Based on historical accounts of a duck-like flight, the Ivory-billed Woodpecker was thought to have duck-like flaps in which the wings remain extended throughout the flap cycle. Although definitive fieldmarks were observed in the field, there seemed to be a contradiction when the video was inspected and found to reveal a flap style that is radically different from what was expected -- the wings are folded completely closed in the middle of each upstroke. This mystery was resolved by a long overlooked clue, a photo from 1939 of an Ivory-billed Woodpecker in flight with the wings folded closed. The observed flap style makes sense in hindsight since it is similar to that of other large woodpeckers.

The flyunder video provides the first putative footage of an Ivory-billed Woodpecker in cruising flight. Since the bird and its reflection from the still surface of a bayou are visible, it is possible to pin down the bird's position (which can't always be deduced from video footage) by triangulation. Since the bird was initially flying nearly directly toward the camera, it was possible to simultaneously extract from the video curves that define both components (horizontal and vertical) of the wingtip motion. Since the bird flew past reference objects, it was possible to estimate wingspan and obtain the first putative data on the flight speed of this species. The video also provides the first putative data on the flap rate. The combination of the wingspan and the flap style rule out all species native to Louisiana except the two large woodpeckers, and in fact an expert on the flight mechanics of woodpeckers, Professor Bret Tobalske, of the University of Montana, is "confident it is a large woodpecker." The Pileated Woodpecker is ruled out by the narrow wing shape, high flight speed, high flap rate, and large white patches on the wings, all of which are consistent with Ivory-billed Woodpecker. The video also shows a trace of white on the back/neck that is consistent with the dorsal stripes that were observed in the field.

Winged hope: Auburn professor is confident the magnificent ivory-billed woodpecker is not extinct Read more: Anniston Star - Winged hope Auburn professor is confident the magnificent ivory billed woodpecker is not extinct

by John Fleming
Editor-at-large Anniston Star
Mar 13, 2011

AUBURN – Professor Geoff Hill is a careful observer and a careful talker.

He knows what he saw, but he also knows what to say about what he saw.

In 2005 and 2006, deep in the swamps of the Florida Panhandle, he made several sightings of an ivory-billed woodpecker, thought to be extinct, last proven beyond a doubt to be alive in the 1940s. The professor of ornithology at Auburn and author of several books on birds, an accomplished birder and a man who knows his woodpeckers (one of his books is about the ivory-bill) will tell you in detail about the Holy Grail of the birding world, because he has firsthand knowledge.

But then he will quickly add, “It proves nothing.”

It proves nothing because neither he nor any of the other accomplished members of the research team he led from Auburn University into the Choctawatchee River basin came back with a clear, indisputable photo of the bird. Yes, they have hundreds of recordings of a distinctive call similar to the one an ivory-bill was known to make. And his team, accomplished birders, well-trained graduate students and fellow ornithologists, made at least 14 sightings.

“It doesn’t prove anything.”

Hill, who has recently returned from studying another dying species in New Zealand, has a video clip of what he says is the bird. But before he even speaks about it, he dismisses it as essentially useless.

The clip is fuzzy and short. If you tease the backstory out of him, he’ll add that on the video, his grad student, Brian Rolek, is heard to say, “ivory-bill.”

Geoff Hill is convinced the ivory-bill is not dead. But he’s having a harder time convincing himself that the research has any more life in it.

A fuzzy video image

Proving the existence of the ivory-bill is a big deal for science and the birding world. This, the largest of the woodpeckers, once occupied the forests and swamps of the South, until huge swaths of timber were cleared, destroying the bird’s habitat.

Once a common sight, the ivory-bill faded with the forests of the South, until scientists and birders stopped finding it at all.

Through the years, people have reported sightings. Many of them turned out to be the cousin of the ivory-bill, the much smaller pileated woodpecker. But sprinkled in among the false alarms have been enough credible reports to keep the scientists and the hopeful interested.

The biggest problem is there is no photo. Not since a scientific expedition penetrated a swampy region of Louisiana to film ivory-bills in the 1930s has anyone obtained an undisputed photo of the bird.

Oh, there have been close calls. But these signs of hope have also proven to be letdowns for the general public and for funders of projects like the one Hill led.

First, there was great excitement in Louisiana in the late 1990s, which turned up practically no evidence. Then a video (another inconclusive affair) from Arkansas sent the birding community into euphoria, until some experts began to cast doubt on it.

This is one reason Geoff Hill is so careful. He doesn’t want to build up expectations, but he’s also a scientist. He has respect for the skeptics, even when they heap scorn on him and his dedicated group that braved the flooded river bottoms of northwest Florida.

There is a new documentary, for example, Ghost Bird, that focuses on the Arkansas episode in the ivory-bill chronicles. It does not heap scorn on Hill and the others, but it takes a decidedly skeptical approach to the question.

In the documentary, hope that the woodpecker is still alive and, by extension, hope for the future of wildlife is given a backseat because Hill and others who share his mostly optimistic view were not interviewed.

But “that’s our fault,” said Hill. “The producer didn’t leave us out of that film, we didn’t give him access.” Hill already had an arrangement with another film producer who asked for exclusive access. So he honored that.

That film has not been made and may never be made, said Hill.

He speaks matter-of-factly, but he is not a defeatist. There has, after all, been some action since his expedition was forced to quit the swamp because the funding had come to an end.

He just wants everyone to understand that none of it is conclusive.

“There is that one weird image,” he said, shaking his head while turning to his computer monitor.

The team, he explained, mounted remote cameras in the forest, cameras that took million of images of squirrels, small birds, ducks and woodpeckers that were not ivory-bills.

Out of more than 7 million images, no bird resembling the big woodpecker showed itself. Except for that one image.

“Well, look at it,” Hill said when he brought the image up on his screen. “What is that? I don’t know, could be an ivory-bill, could be a cormorant, could be herons. It’s like an inkblot. It gets us nowhere.”

Deep in the Choctawatchee

Then there is the interesting case of a group that traveled from across the nation to the Choctawatchee at the end of Hill’s research effort in 2008.

Among them was John Agnew, an accomplished wildlife artist from Cincinnati, Ohio. Agnew was in a kayak working along a tributary called Bruce Creek, in the same area where Hill’s group had spent a lot of time and previously spotted the bird.

In his article in Bird Watcher’s Digest, he described what happened to him that cold morning in early 2008:

“About a hundred yards to the west of me, some pileated woodpeckers were making a racket, apparently involved in a territorial dispute. It was then that I saw a large dark woodpecker flying towards me from their direction. It landed on the far side of a cypress about 20 yards away. I thought that I might as well practice my photographic technique on this pileated woodpecker, and was raising the camera (a Nikon D80 with a 300mm lens) to focus when it took off and flew directly towards me. There would not be time to get the camera ready, so I just watched this magnificent bird fly. When it was about 15 feet overhead and nearly at my position, I realized that something was different. My eyes were drawn towards the brilliant white secondary feathers, their edges glowing in the morning sun. My subconscious mind was telling me that this was no pileated, but no alarm bells were ringing. I noted the red crest and a white stripe on the side of the head. The bird flew past me, and by the time I got the kayak turned around, it had gone on downstream. I sat a moment digesting what I had seen.”

The pileated is about the only bird, according to Hill, that you could possibly confuse with the larger ivory-bill. But Agnew went on to say that he is intimately familiar with the pileated woodpecker, and what he saw was not a pileated, but an ivory-bill.

Perhaps most importantly, Agnew noted the white trailing edges of the underwing of the bird, a signature of an ivory-bill.

When he reached his friend Sally Wolliver, who was a short distance away but out of sight down Bruce Creek, he found her “gesturing wildly and mouthing the words, ‘I saw an ivory-bill.’”

Wolliver, a south Florida veteran of many a birding outing, agreed with Agnew that they had almost certainly seen the same bird, and that it was an ivory-bill.

Agnew, the artist, drew his own sketch after the sighting. Wolliver described what she had seen to artist Devere Burt, who was also on the trip and who serves as director emeritus of the Cincinnati Museum of Natural History.

“My back was against a cypress tree,” Wolliver said in a recent phone call. “It was early morning, cold but spectacular. Coming toward me on Bruce Creek was what I thought was a pileated woodpecker. But when it turned, I could see how big it was.”

Wolliver described the flying pattern as “zipping,” not undulating or up and down, a description often given to pileated woodpeckers.

“Then,” Wolliver said, just before the bird disappeared out of sight, she saw “a white trailing pattern” on the wing.

Ivory-bills are strong flyers, with rapid wing thrusts, and, again, the underwing and trailing edge of the wing is white.

In his office in Auburn, with books about ivory-bills, sketches of ivory-bills and research about birds all around him, Hill talked about this sighting and the respect he has for both Agnew and Wolliver, and how in all likelihood they saw an ivory-bill, maybe the last one on earth.

“But,” he said, turning his attention back to class preparation, “it doesn’t prove anything.”

Does the ivory-bill still exist?

Ivory-bill woodpecker - Unlikely.

Written by By Rodney Barreto, Chairman of the Florida Fish and Wildlife Conservation Commission

December 2010. In the spring of 2005, news swept the United States and much of the world that the ivory-billed woodpecker, long thought to be extinct, had been found in the Cache River National Wildlife Refuge in Arkansas. The news was electrifying to birders and conservation groups.

The Nature Conservancy offered a reward for finding an Ivory-billed woodpecker of $50,000. It has not been paid.



Gene Sparling, an amateur ornithologist from Hot Springs, Ark., had reported seeing one adult male ivory-bill in the Cache River refuge on Feb. 11, 2004. Other ornithologists soon searched for documentation and proof that ivory-bills still existed. They seemed to make their case when David Luneau of the University of Arkansas at Little Rock made a short, blurry videotape of a reported ivory-bill taking flight from a tree.

Some of the groups that reviewed the evidence and supported the claim that the woodpecker, with its 3-foot wingspan and signature whitish-ivory bill, still existed included the Cornell Laboratory of Ornithology, National Audubon Society, The Nature Conservancy and the U.S. Fish and Wildlife Service. Some wanted to believe that the gigantic woodpecker, known by such names as white-back, pearly bill and even Lord God bird, still flew safely somewhere. The name "Lord God bird" came from people seeing the bird and exclaiming, "Lord God, what a bird!"

Had the short video clip been clear, that would have been one thing. However, ornithologists across the country weighed in, and many believed the searchers had spotted the smaller, common pileated woodpecker.

Not long after the reported Arkansas sighting, a team led by an Auburn University professor said it had audio recordings of what members believed were the sounds of one or more ivory-bills in the Choctawhatchee River basin in the Florida Panhandle. The Florida Fish and Wildlife Conservation Commission (FWC) mobilized a team to deal with questions and issues about the Choctawhatchee finding, which proved untrue.

To understand the discussion as to whether ivory-bills still exist, you have to understand something of the bird itself and the history of our country.

Ivory-bill ID
Adult ivory-bills measured 19 to 21 inches, were bluish-black in color and had white markings on the neck, sides and back, resembling a white saddle. Both male and female birds sported a prominent top crest, which was red in males and black in females.

Early settlers and frontiersmen reported that male Native American Indians, particularly chieftains, wore the bills of ivory-billed woodpeckers on their belts or as part of breast plates. The author of "In Search of the Ivory-Billed Woodpecker," Jerome A. Jackson, points to the archaeological record showing that the heads and bills of both ivory-billed and pileated woodpeckers were much in demand by Indians, sometimes far outside the birds' range. He mentions the recent discovery of an Indian burial in Colorado with ivory-bills on the deceased, more than 1,000 miles from recognized ivory-bill habitat.

Jackson and other authors accurately point to the fact that Indians armed with bows and arrows weren't the death knell of the species. Logging was.

Ivory-bill habitat and distribution
Ivory-bills were found primarily in the Southeast's virgin hardwood forest river bottoms and longleaf pine forests, and were well documented in Florida and a dozen other southeastern states. With their powerful chisel-like bill, they foraged on lots of dying and dead trees. such as sweet gums, ash and longleaf pine, removing the bark in search of insects and larvae. Ornithologists say ivory-bills needed immense areas to feed - perhaps 10 to 12 square miles of old-growth forest per pair.

As one forest after another fell to an expanding country's insatiable demand for wood, ivory-bills began to vanish. Ornithologists say the species was extremely rare after 1900. Nowhere was this more evident than in Florida.

What are the chances?
Whether an ivory-bill was actually spotted in the Cache River NWR is still a matter of debate. I have my own ideas, but if the sighting was accurate, it would have required dozens and dozens of breeding pairs of birds over the past 100 or so years for birds to still exist today.

Following the Cache River announcement, river-bottom searches were initiated in Florida and five other states. No definitive sightings emerged.

We still have the pileated relative of the ivory-bill. Yet we want to believe the most magnificent of North American woodpeckers still exists, somewhere. Although it seems unlikely, time will tell.

Ivory-bills were found primarily in the Southeast's virgin hardwood forest river bottoms and longleaf pine forests, and were well documented in Florida and a dozen other southeastern states. With their powerful chisel-like bill, they foraged on lots of dying and dead trees. such as sweet gums, ash and longleaf pine, removing the bark in search of insects and larvae. Ornithologists say ivory-bills needed immense areas to feed - perhaps 10 to 12 square miles of old-growth forest per pair.

As one forest after another fell to an expanding country's insatiable demand for wood, ivory-bills began to vanish. Ornithologists say the species was extremely rare after 1900. Nowhere was this more evident than in Florida.

What are the chances?
Whether an ivory-bill was actually spotted in the Cache River NWR is still a matter of debate. I have my own ideas, but if the sighting was accurate, it would have required dozens and dozens of breeding pairs of birds over the past 100 or so years for birds to still exist today.

Following the Cache River announcement, river-bottom searches were initiated in Florida and five other states. No definitive sightings emerged.

We still have the pileated relative of the ivory-bill. Yet we want to believe the most magnificent of North American woodpeckers still exists, somewhere. Although it seems unlikely, time will tell.
