AWAY DOWN in the swampy bottomlands of Dixie, the most intensive search eve=
r
for a bird is gearing up for a make-or-break season. Big reputations are
riding on the controversial quest for the ivory-billed woodpecker, the most
magnificent and most elusive of America=B9s tree-knockers.

Here in the vast White River National Wildlife Refuge, naturalists are
trying to confirm hotly-debated sightings of a bird written off as extinct
until four years ago. The terrain is tough and even treacherous. Catclaw
briars snag boots, whip vines slash faces, and cruel honey-locust thorns
stab through clothing and skin. Cold muddy water can rise to the armpits of
researchers fording swamps in duct tape-patched waders.

"It=B9s a labour-intensive slog, for the most part. Not an idyllic ramble,"
said Martjan Lammertink, project scientist for an ivory-billed research tea=
m
from Cornell University. He lowered his binoculars after long scrutiny of a
nesting cavity carved by a woodpecker beak into the upper trunk of a dead
ash tree, finally pronouncing, "Too neat and only 3-1/4 inches =8B too small.=
"

The camouflage-clad scientists, venturing into what one described as the
"most woodpeckeriest" woods to be found from South Carolina to East Texas,
are backed by an array of high-tech tools, from GPS co-ordinate monitors to
satellite imagery. Automatic cameras catch digital images, their infrared
flash strobes blinking near rotted trees and other likely roosting sites.

This month, for the first time, U.S. Fish and Wildlife Service helicopters
were enlisted in the chase, flying low-level "flush" missions meant to spoo=
k
birds into breaking from the treetops. The idea is that airborne scientists
might catch a glimpse of an ivory-billed and supply coordinates to help
ground teams hone searches ongoing across hundreds of thousands of
wilderness acres.

The last ivory-billed sighting claimed by a bird scientist occurred on
Valentine=B9s Day 2005, in Arkansas, when a researcher from Cornell=B9s famed
Laboratory of Ornithology, Casey Taylor, spied what she is convinced was on=
e
of the huge woodpeckers being harried by a mob of crows.

But skeptics scoff at that sighting almost as loudly as they jeer at a fuzz=
y
2004 videotape purporting to show an ivory-billed. Such critics say the
woodpecker has almost certainly been extinct since the 1940s and that the
search is a colossal waste of money and scientific energy. They maintain
ivory-billed scientists, however expert, are simply fooled by glimpses of
similar-looking =8B but commonplace =8B pileated woodpeckers.

The dispute has shaken the bird community, with mud-slinging between
prominent biologists. Doubters last year used a professional journal to
accuse the ivory-billed scientists of practicing "faith-based ornithology."

Meanwhile, in the real muck of the bottomlands, the search continues.

The best hope is that a few breeding pairs of ivory-billeds linger in
isolated floodplain forests. These forests were cut down by loggers startin=
g
in the 19th century and continued until a few decades ago. Because the
ivory-billed=B9s big body needs more food than smaller woodpeckers, the birds
require substantial tracts of "old growth" trees on which to forage. Male
ivory-billeds, measuring 50 centimetres tall with a half-metre wingspan,
boast brilliant red crests. Both sexes possess jagged white stripes that
resemble lightning bolts. Their tallow-colored beaks shred through bark,
allowing them to impale beetle grubs with long, harpoon-like barbed tongues=
.

"The decline of the ivory-billed is an unspeakable American tragedy," said
John W. Fitzpatrick, director of the Cornell lab. "This country was unable
to save even a single square metre of pristine bottomland habitat."

For a trio of scientists from Cornell, last Wednesday was a more or less
typical day of field work =8B one that started before dawn with departure fro=
m
the duck-hunting lodge that is their temporary home and ended in the
darkness as they clambered, filthy, from the bayou. Lammertink, project
biologist Martin Piorkowski, and camera specialist Abe Borker would spend 1=
1
hours forging 25 kilometres through woods and swamp land, seeking signs of
large woodpecker.

The scientists moved cautiously, making little noise even slipping through
bramble thickets. At the barest hint of movement =8B a tiny flutter of
feather, say, in a tangle of branches =8B the trio would freeze, three pairs
of powerful binoculars snapping instantly to three keen pairs of eyes.

They made fast identifications sotto voce, in near unison.

"Red-breasted woodpecker."

"Yellow-rumped warbler."

"Rusty blackbird."

These weren=B9t the quarry. Naming them was just professional reflex.

Part of this day=B9s job was locating some of the dozen Reconyx cameras
strapped to trees facing possible roosting holes. Each camera snaps an imag=
e
every four seconds for two hours at sunrise and in late afternoon, times
when nesting ivory-billeds should be lurking close to home. As he downloade=
d
a week=B9s worth of images =8B some 25,000 pictures =8B from one camera, Borker
reflected on the uncertainty of pursuing a bird that might be ghost. "You=B9v=
e
got to start every day with fresh optimism: This will be the day we prove
this bird (is alive)."

Last week=B9s long days ended in disappointment: No ivory-billeds spotted, no
fantastically encouraging signs. Just the grunt work of bird science.

Winter is prime time to go looking for the ivory-billed. The deciduous
foliage is gone, allowing longer views. Seasonal flooding makes it possible
to venture by canoe or kayak into the deepest swamps. Most critically,
midwinter is when ivory-billeds should be thinking about love, using
powerful muscles and long beaks to send out their double-rap knock as a
signal of yearning for the opposite sex.

The South-wide search is partly bankrolled by an annual $1.2 million in
grants from the U.S. Fish and Wildlife Service. "We think a few breeding
pairs may be out there. And we feel like Arkansas is the strongest bet,"
said Laurie Fenwood, co-ordinator of the service=B9s ivory-billed woodpecker
program. "If we keep coming up empty, though, big decisions will have to be
made."

The ivory-billed became a household name across America following its
"rediscovery" in Arkansas in 2004 (the mystery bird caught on video plus
multiple "eyeball" sightings by Cornell scientists were officially announce=
d
in 2005).

The comeback of a creature thought extinct triggered jubilation among
wildlife lovers and even excitement among nonbirders who normally wouldn=B9t
know a bobolink from a turkey buzzard. Headlines proclaimed an ecological
miracle and celebrated the Cornell lab.

Fitzpatrick, a foremost ornithologist, put the university=B9s Ivy League
prestige behind the four-second video taken by M. David Luneau Jr., an
engineer and amateur birder who had volunteered to help the Cornell search.
The video became "Exhibit A" for those insisting the bird has survived more
than a century of depredations by clear-cutting loggers and expansionist
farmers.

The federal government pledged $27 million for an ivory-billed "recovery"
program. Then came skeptics, arguing the videotape showed a pileated
woodpecker. Talk show hosts compared the ivory-billed reports to "Elvis
sightings."

Ornithologists also made at least seven "hard" ivory-billed visual sighting=
s
near Arkansas=B9 Cache River in 2004 and 2005, although they didn=B9t get
photos. Such identifications by scientists would usually be taken as
conclusive evidence.

The rift has become so bitter that neutral biologists are hard to find.
Harvard=B9s E.O. Wilson comes close; he fears the 2004-05 sightings might
merely represent a single freak survivor, doomed without a mate. But Wilson
is also adamant that a major search should continue so long as there is a
glimmer of hope.

"Sadly, reports of the ivory-billed=B9s extinction may be true =8B I don=B9t see
much more than a 10 per cent chance we=B9ll ever see a live one," Wilson said
in an interview last month, shortly after a trip to the Choctawhatchee
River. "But great science discoveries have come from longer odds."

[NOTE FROM JIM WOLFORD: note reference above to CHOCTAWHATCHEE RIVER -- thi=
s
is in the western panhandle region of FLORIDA, a completely different area
with some very promising sightings and hearings of one to two ivory-billed
woodpeckers in recent years by another team of researchers.  THIS ARTICLE
doesn't even mention what has happened and is happening? in Florida, and it
also doesn't really give much of an idea of what if anything has been found
in Arkansas in the past year or two of research.]
