OUR MONTHS LATER, TANNER WAS BACK IN THE SOUTH. HIS RESEARCH OF THE PREVIOUS spring had narrowed down the number of likely habitats for Ivory-bills, and there was no time to waste. The place he wanted to explore most was a swamp around the Santee River in South Carolina. Museum specimens and local reports left no doubt that many Ivory-bills had once lived there. Local experts confidently predicted that eight to twelve nesting pairs still remained.
By now the Ivorybill was to be found only in one place: the Singer Tract in northeastern Louisiana
Early in December, Tanner and a guide pulled on their boots and set out to comb every part of the Santee swamp for Ivory-bills. Eleven days later they came back disappointed. While they had seen a few stripped trees, Tanner wasn't sure Ivory-bills had done the work. And they hadn't heard a single call.
The Santee search made Tanner rethink how much habitat Ivory-bills really needed. “I believe [the local experts] have underestimated the range of the birds, and so overestimated the numbers,” he wrote. In short, he feared that there wasn't nearly enough food for eight to twelve pairs in a forest the size of the Santee's. He thought
back to the Ivory-bill family he had studied in the spring at the Singer Tract. They were nomads. Within a month, even the little bird had been able to fly two miles from its home tree in search of food. He realized that it must take a lot of territory to contain enough food for a family of Ivory-bills. The Santee was less than half the size of the Singer Tract. Tanner figured it was big enough for only two, maybe three, pairs at most.
THE CAROLINA PARAKEET
Southern U.S. forests once teemed with emeraldgreen parakeets sporting a bold yellow streak where the wing met the body and a bloodred patch around the eye. Audubon said they were so abundant that they covered orchards “like a brilliant coloured carpet.” Now the species is extinct. Why? Farmers killed them because they ate fruit. Market hunters shot, stuffed, and sold them to collectors. Hatmakers loved the green plumes, and hunters found the birds easy targets. When one bird lay dead on the ground, others in a flock often joined it, making themselves targets, too. The last Carolina Parakeet, Inca, died in the Cincinnati Zoo in 1918.
With this ominous new theory, Tanner gunned the engine of his Ford and swung toward Louisiana, racing through the Georgia hills and across the Mississippi to Tallulah in a single day. By dusk Tanner and J. J. Kuhn were walking single file long the slippery trail to their cabin, balancing sacks of groceries on their shoulders as they picked their way around mud-holes and stepped over logs.
Beginning at dawn the next day, Tanner explored the Singer Tract day and night. Step by step he learned where the bayous ran and how the forest changed from its flat soggy bottom, laced with vines, to its drier ridges. He came to sense the subtle changes of the seasonsâthe lengthening of shadows, the fragrance of blossoming vines, the smell of wet leaves, and the steady electric hum of insects. Finally these patterns converged into a picture of the whole magnificent forest.
Tanner's visits to other swamps in the South had usually been disappointing because loggers had sliced the forests up into small patches. Less than halfway through his study, he began to suspect that the Singer Tract was the last big uncut swamp forest left in the entire Mississippi deltaâmaybe in the whole South. The Singer Tract was the one forest that looked and felt and smelled and sounded as it must have thousands of years before. There was a good chance that every single species that had ever lived in this forest was still there except for the Carolina Parakeet and the Passenger Pigeonâboth extinct. Everything elseâfrom Ivory-bills, panthers, and wolves to grubs, mites, and frogsâwas still there.
Feather-topped cypress trees fringed the lakes inside the Singer Tract
Tanner was beginning to realize that in order to understand the Ivory-bill's life history, and to save it at the Singer Tract, he had to know the forest completely, to understand it as a single colossal organism throbbing with life. So the whole forest became Tanner's lab, and it fascinated him as much as any species within it, even the Ivory-bill. Often he began hiking before the sun rose and was still out after dark.
Winter was by far Tanner's favorite season. Ivory-bill calls carried a long distance through the leafless forest, and he could spot the birds more easily when they flew through the bare limbs. Plus, there were no mosquitoes or snakes. One winter morning he made his way to an Ivory-bill roost tree while it was still dark, hours before the woodpeckers would be active. Plumping up a cushion of palmetto fronds, he settled himself against a tree to hear the forest wake up. It was great entertainment, he thought, and he didn't even need a ticket.
Just as the first pink stripe appeared behind the black-silhouetted trees, Barred Owls signed off the night shift with their final
“Who cooks for you, who cooks for you
-
call”
hoots. The spreading sunlight brought the day crew to life, singer by singer and song by song.
THE RED WOLF
A Red Wolf can be any color from tan to black. Smaller than its cousin the Gray Wolf, it once hunted deer and smaller mammals in forests, marshes, and swamps from Pennsylvania to Texas and in southeastern states. Many were shot and trapped early in the twentieth century as suspected killers of cows and sheep. At the same time, their habitat was cleared and drained.
By the late 1930s, only two populations remained in the United States, including some at the Singer Tract. In 1967, the Red Wolf was declared endangered. Six years later, with the species nearing extinction, biologists captured 14 wolves so they could breed in safe, zoo-like situations. Now there are 270 to 300 Red Wolves, of which 50 to 80 live in the wild.
Brown Thrashers led off the dawn chorus with a hoarse, once-repeated
churr
that welled up from the brambles. White-throated Sparrows chimed in next, with a high melody whose first four notes sounded like “Here comes the bride.” Then the amazing Winter Wrens burst onto center stage, stub-tailed midgets who threw back their heads and belted out the longest song of any bird, rattling their entire frames with the effort. By the time the late-sleeping Ivory-bills finally appeared at their hole to preen their feathers, the forest was bathed in light. By then, Tanner noted, seven other woodpecker species had already called.
Sometimes surprise guests appeared during his silent vigils. One December morning Tanner was seated on the ground, listening for Ivory-bills, when the vines in front of him rustled and the stiff palmetto fronds gave way to something big and
solid. At first the glossy black back that passed slowly before his eyes seemed to belong to a small horse. Then, suddenly, he realized it was a wolf walking along a log. When it plopped silently to the ground and vanished into a thicket, Tanner raised himself to a half crouch so he could see better. The wolf came out of the brush and passed slowly across a clearing maybe thirty steps away. “He was handsome, powerful ⦠with a deep chest and a lean belly, self confident, alert ⦠black from tip to tail,” Tanner wrote. Cupping his hands, Tanner tried to squeak like a wounded bird to catch the wolf's attention, but it trotted off.
The forest became silent and still at midday, when creatures active in daylight hours seem to take a break. The forest pulse quickened again at dusk and stayed brisk until sundown, which ushered in a whole new cast of characters. One night Tanner rowed a small wooden boat out into the middle of a lake, put his oars at rest, and remained silent as he scanned the moonlit water. “The forest stretched away for miles from the black wall of trees surrounding the lake,” he later wrote. “The air shook with noise ⦠The chorus of frogs came from all sides ⦠loudest by weight of numbers were the tiny cricket frogs on the floating duckweed ⦠sitting and beating out their rasping notes.” He flicked on a flashlight. The beam swept across the surface of
the water until it caught “a glowing coal that burnt for a moment and then went outâthe eye of an alligator that sank beneath the surface.”
Day or night, poisonous snakes were a huge worry, especially around Greenlea Bend. Timber Rattlesnakes slithered out from their winter dens just as spring covered up the foot trails with vines, leaves, and brambles. The “thick-bodied water moccasins” and Copperheads that Theodore Roosevelt had seen on his hunting trip were still there, too, and plenty of them. Since Tanner and Kuhn couldn't look up for birds and down for snakes at the same time, there were many unscheduled meetings. Once, as Kuhn went charging through a thicket of vines after a bird, his boot came down on a rattler. The unmistakable sound sent him leaping in the only direction he couldâstraight up. Then, penned in by brambles on all sides, he landed on the only place he couldâstraight down. The snake was still there, rattling away. Heart pounding, Kuhn jumped again, with the same result, and kept on jumping until the snake darted away.
In spring and summer, the two men wore long-sleeved shirts with all the buttons closed tight to the neck and the collars turned up, and sometimes they wore their hats jammed down over their ears. But still the insects bit and stung them. Annoying as it was, it gave them something in common with all the other warm-blooded creatures of the forest, and they had no choice but to accept it.
The most awesome event in the woods occurred when one of the giant trees fell. This usually happened after a hard rain, when a grand old monarch's soaked crown became so heavy that the trunk could not hold it up any longer. Then, as Tanner wrote, “the quiet of the woods would suddenly be broken by a resounding crack ⦠then a series of loud snaps merging into a roaring crescendo as the tree crashes downwards to hit the earth with a dull, echoing boom. The echoes quickly die away, but the forest still seems to hold its breath until gradually the birds resume their song, the normal quiet sounds return, and the listener collects his scattered thoughts.”
In the evenings, Kuhn and Tanner ate their supper together by a kerosene lamp on the cabin's screened-in porch. Since they often split up during the day, they used the night to catch up. “We talked ⦠just as Mark Twain's river pilots endlessly discussed the details of the river's course,” wrote Tanner. “Although learning of the Ivory-bill and its life history was our goal, the forest was our working place and we had to know itâ[how] to find our way, to travel quickly and to know where to hunt.”
