Audubon's 'Cache-Lower White Rivers
Important Bird Area' Is Home to Ivory-billed Woodpecker
April 28, 2005 -- Little Rock, AR. The confirmed sightings
of an Ivory billed Woodpecker on an Audubon designated Important
Bird Area which encompasses the Cache-Lower White Rivers National
Wildlife Refuges is like "finding the Holy Grail of Ornithology,"
said Ken Smith, Director of Audubon Arkansas.
"This is terrific news in Audubon's 100th anniversary
year," he continued. "Audubon has a long history
of trying to preserve this and other birds from extinction.
In 1943, National Audubon campaigned to preserve a tract in
Louisiana where the birds had been sighted, but unfortunately
the last sighting there occurred in 1944."
With a distinctive white bill and a dramatic crest, the large
woodpecker was thought to be globally extinct with the last
documented sighting in Cuba in 1987. A report in 1999 in the
Pearl River Wildlife Management Area, Louisiana led to a concerted,
high-tech search of the area in 2002, but no birds were found.
The Cache-Lower White Rivers Important Bird Area is as logical
as any a place for the bird to be found in the United States.
It is described on the Important Bird Area nomination form
as "a large contiguous stand of bottomland hardwood forest
that makes it one of the few prime locations in the Mississippi
Alluvial Valley capable of supporting populations of all forest
breeding birds within breeding range." It is also noted
as the most important wintering area for Mallards in North
America.
The Mississippi Alluvial Valley Migratory Bird Initiative
designated this site as a 100,000-acre patch of bottomland
hardwood forest to support the conservation of forest breeding
birds. Additionally, the Ramsar Convention named it a "Wetland
of International Importance" in 1989.
Important Bird Areas provide essential habitat for one or
more species of bird, and meet criteria established by Audubon
Arkansas' Important Bird Area Technical Committee, which includes
many of the state's leading ornithologists.
"Finding the Ivory-billed Woodpecker on an Important
Bird Area reinforces the urgency for conservation of such
sites. While Important Bird Areas vary greatly in terms of
land ownership, habitat type and bird usage, they all are
critical for the survival of birds significant not only to
Arkansas but, as we now know, to the world." said Dr.
Daniel Scheiman, Director of Bird Conservation for Audubon
Arkansas.
Audubon is dedicated to protecting birds and other wildlife
and the habitat that supports them. Our national network of
community-based nature centers and chapters, scientific and
educational programs, and advocacy on behalf of areas sustaining
important bird populations, engage millions of people of all
ages and backgrounds in positive conservation experiences.

CONSERVATIONISTS
WORLDWIDE CELEBRATE REDISCOVERY OF IVORY-BILLED WOODPECKER
FACT SHEET
Ivory-billed Woodpecker
Range: The Ivory-billed Woodpecker
was once found in virgin forests throughout much of the southeastern
United States, and up the Mississippi and Ohio Rivers at least
as far north as St. Louis. It was also known from mature forests
through much of Cuba.
Habitat: U.S. birds preferred bottomland
swamp forests. Primarily associated with extensive old-growth
forests, the solitude of wilderness, and the availability
of immense beetle larvae that were its principal food.
Characteristics essential in habitat include: (1) very extensive,
continuous forest areas, (2) very large trees, (3) agents
of tree mortality that result in a continuing supply of recently
dead trees, and (4) an open forest through which such a large
bird can fly.
Body size: 19 inches long with
a 31-inch wingspan. Larger than the Pileated Woodpecker. Larger
than a Crow.
Appearance: Large size, white bill,
and largely white wing separate this bird from the Pileated
Woodpecker. It is the third largest woodpecker on earth.
Lifespan: Unknown, though the similarly
sized Pileated Woodpecker can live over 9 years.
Food: Prefers large beetle larvae
found beneath the bark of recently dead trees.
What to listen for: A tooting call
like the sound of a tin horn. Drumming is a double rap with
an echo-like cadence.
What to look for: Extensive scaling
of bark associated with foraging and nest sites.
Threats: Primary negative impact
of humans is destroying or fragmenting their habitat. Other
factors that contributed to their reduction include killing
the birds, and possibly disrupting their normal behavior patterns.
Status: It is one of the rarest
birds in the world. A Federally endangered species.
History: The Ivory-billed Woodpecker
was first described in 1731. A century later John James Audubon
painted the bird and wrote a detailed description in his "Birds
of America." In the 1870s new technology started a lumber
boom in the southern forests, and by the end of the decade
the bird was reported as being not at all abundant. After
years without a sighting, Arthur A. Allen, founder of the
Cornell Laboratory of Ornithology, rediscovered the bird in
Florida in 1924. In 1935 he made the first and only audio
and video recordings. Sponsored in part by National Audubon
Society, James Tanner conducted a detailed study of the species'
biology, ecology, and distribution in the late 1930s. He estimated
there were only 25 birds left in the US, but found only 6
in the Singer Tract, Louisiana. National Audubon campaigned
to preserve the land in 1943, but the last documented sighting
occurred in April 1944. The species was thought to be globally
extinct with the last documented sighting in Cuba in 1987.
A credible report in 1999 in the Pearl River Wildlife Management
Area, Louisiana led to a concerted, high-tech search of the
area in 2002, but no birds were found.
