Long Feared Extinct, a Magnificent Bird Still Lives

Long
believed to be extinct, a magnificent bird--the Ivory-billed
Woodpecker--has been rediscovered in the Big Woods of eastern Arkansas.
More than 60 years after the last confirmed sighting of the species in
the United States, a research team today announced that at least one
male ivory-bill still survives in vast areas of bottomland swamp forest.
Published in the journal Science on its Science Express web site
(April 28, 2005), the findings include multiple sightings of the
elusive woodpecker and frame-by-frame analyses of brief video footage.
The evidence was gathered during an intensive year-long search in the
Cache River and White River national wildlife refuges involving more
than 50 experts and field biologists working together as part of the
Big Woods Conservation Partnership, led by the Cornell Laboratory of
Ornithology at Cornell University and The Nature Conservancy.
"The bird captured on video is clearly an Ivory-billed Woodpecker," said John Fitzpatrick, the Science
article's lead author, and director of the Cornell Laboratory of
Ornithology. "Amazingly, America may have another chance to protect the
future of this spectacular bird and the awesome forests in which it
lives."
"It
is a landmark rediscovery," said Scott Simon, director of The Nature
Conservancy's Arkansas chapter. "Finding the ivory-bill in Arkansas
validates decades of great conservation work and represents an
incredible story of hope for the future."
Joining
the search team at a press conference in Washington DC, Secretary of
the Interior Gale Norton announced a Department of the Interior
initiative to identify funds for recovery efforts. Through its
cooperative conservation initiative, the Fish and Wildlife Service has
a variety of grant and technical aid programs to support wildlife
recovery.
"These
programs are the heart and soul of the federal government's commitment
to cooperative conservation. They are perfectly tailored to recover
this magnificent bird," Secretary Norton said. "Across the Nation,
these programs preserve millions of acres of habitat, improve riparian
habitat along thousands of miles of streams and develop conservation
plans for endangered species and their habitat."
The
largest woodpecker in North America, the Ivory-billed Woodpecker is
known through lore as a bird of beauty and indomitable spirit. The
species vanished after extensive clearing destroyed millions of acres
of virgin forest throughout the South between the 1880s and mid-1940s.
Although the majestic bird has been sought for decades, until now there
was no firm evidence that it still existed.
The
rediscovery has galvanized efforts to save the Big Woods of Arkansas,
550,000 acres of bayous, bottomland forests and oxbow lakes. According
to Simon, The Nature Conservancy has conserved 18,000 acres of critical
habitat in the Big Woods, at the request of the partnership, since the
search began. "It's a very wild and beautiful place," Simon said.
While
kayaking in the Cache River National Wildlife Refuge on Feb. 11, 2004,
Gene Sparling of Hot Springs, Ark., saw an unusually large, red-crested
woodpecker fly toward him and land on a nearby tree. He noticed several
field marks suggesting the bird was an Ivory-billed Woodpecker.
A week later, after learning of the sighting, Tim Gallagher, editor of the Cornell Lab of Ornithology's Living Bird
magazine, and Bobby Harrison, associate professor at Oakwood College,
Huntsville, Ala., interviewed Sparling. They were so convinced by his
report that they traveled to Arkansas and then with Sparling to the
bayou where he had seen the bird.
On
Feb. 27, as Sparling paddled ahead, a large black-and-white woodpecker
flew across the bayou less than 70 feet in front of Gallagher and
Harrison, who simultaneously cried out: "Ivory-bill!" Minutes later,
after the bird had disappeared into the forest, Gallagher and Harrison
sat down to sketch independently what each had seen. Their field
sketches, included in the Science article, show the characteristic patterns of white and black on the wings of the woodpecker.
"When
we finished our notes," Gallagher said, "Bobby sat down on a log, put
his face in his hands and began to sob, saying, 'I saw an ivory-bill. I
saw an ivory-bill.'" Gallagher said he was too choked with emotion to
speak. "Just to think this bird made it into the 21st century gives me
chills. It's like a funeral shroud has been pulled back, giving us a
glimpse of a living bird, rising Lazarus-like from the grave," he said.
The
sightings by Sparling, Gallagher and Harrison led to the formation of a
search team, which later became the Big Woods Conservation Partnership.
On April 5, 10 and 11, three different searchers sighted an ivory-bill
in nearby areas. The views were fleeting, leaving little opportunity to
take photographs.
David
Luneau, associate professor at the University of Arkansas at Little
Rock, said he thought the best chance to film the elusive bird would be
to have a camcorder on at all times. On April 25, Luneau captured four
seconds of video footage showing an Ivory-billed Woodpecker taking off
from the trunk of a tree.
Frame-by-frame
analyses show a bird perched on a tupelo trunk, with a distinctive
white pattern on its back. During 1.2 seconds of flight, the video
reveals 11 wing beats showing extensive white on the trailing edges of
the wings and white on the back. Both of these features distinguish the
Ivory-billed Woodpecker from the superficially similar, and much more
common, pileated woodpecker.
On
three occasions, members of the search team heard series of loud
double-raps, possibly the Ivory-billed Woodpecker's display drumming.
On Feb. 14, 2005, Casey Taylor of the Cornell Lab of Ornithology heard
the drumming for 30 minutes, then watched as an Ivory-billed
Woodpecker, being mobbed by crows, flew into view.
In
addition, autonomous recording units detected sounds, among thousands
of hours of recordings, which resembled double-raps and possible calls
of the ivory-bill -- reminiscent of the sound of a tin horn.
Researchers say ongoing analyses of the recordings have not yet enabled
them to rule out other potential sound sources, such as the calls of
blue jays, which are notorious mimics.
In
all, during more than 7,000 hours of search time, experienced observers
reported at least 15 sightings of the ivory-bill, seven of which were
described in the Science article. Because only a single bird
was observed at a time, researchers say they don't yet know whether
more than one inhabits the area.
So
far, the search team has focused its efforts in approximately 16 of the
850 square miles in the bottomland forests of Arkansas. Fitzpatrick of
the Cornell Lab of Ornithology said that the next step will be to
broaden the search to assess whether breeding pairs exist and how many
ivory-bills the region may support. To expand the area being monitored
and minimize disturbance to the endangered woodpecker, the team will
continue to use acoustic monitoring technologies as well as
on-the-ground searching. Fitzpatrick said the team will also encourage
others to search for the ivory-bill elsewhere in suitable habitats
throughout the South.
Simon
of The Nature Conservancy said that over the years, state and federal
agencies, conservation organizations, hunters and landowners have
aggressively worked to conserve and restore the bottomland hardwood and
swamp ecosystem. "Now we know we must work even harder to conserve this
critical habitat -- not just for the Ivory-billed Woodpecker, but for
the black bears, waterfowl and many other species of these unique
woods," he added.
The
partnership's 10-year goal is to restore 200,000 more acres of forest
in the Big Woods. The effort will include conserving forest habitat,
improving river water quality, and restoring the physical structure of
the river channels, focusing in locations with maximum benefit in
reconnecting forest patches and protecting river health.
"The ivory-bill tells us that we could actually bring this system back to that primeval forest here in the heartland of North America," said Fitzpatrick, who is also a member of The Nature Conservancy's board of governors. "That's the kind of forest that I hope some generation of Americans and citizens of the world will get to come and visit."
