Spix's Macaw is last to fly free

Brazil's
animal trade under fire
CURACA,
Brazil -- At sunset every night in the thorny wilderness outside
this small northeastern town, people wait anxiously until the caraibeira
trees beside a dry creek bed erupt in parrot calls that sound like
a child's laughter.
Then
everyone sighs with relief as a long-tailed, deep-blue form streaks
by. It's another appearance by the Spix's Macaw (Cyanopsitta spixii),
the last of its species to fly free. Only about three dozen of the
birds survive in private collections; many of the rest succumbed
to human or animal predators.
"Every
time I see him, it's unique," said biologist Yara de Melo Barros,
who has studied the macaw since 1996. "The risk of his dying
is so great that every time he appears, it's like a victory."
This
year, there's new hope in a campaign to make the little blue macaw,
as it's known here, less of a loner. The effort is a striking example
of international cooperation against the forces of extinction, embodied
in the multibillion-dollar global business of animal trafficking.
And it's inspired by the Romeo-and-Juliet cross-species romance
between the handsome Spix's and a bright green Iliger Macaw, which
ornithologists hope will be able to raise Spix's fledglings born
in captivity.
The
gray-headed, yellow-eyed little blue macaw has always lived only
in this drought-parched region known as the caatinga. Its ranks
were never great, and as increased goat-herding has nibbled away
at its habitat, they have steadily diminished.
In
the wild-animal trade, the third most lucrative illegal global business
after drugs and guns, the Spix's was prized as much for its rarity
as for its beauty, a top-level trophy among the 16 macaw species
in Latin America, more than half of which are endangered. In the
late 1980s, there were reports of the Spix's selling for tens of
thousands of dollars in Europe.
Spotted
again
By 1990, many ornithologists were convinced the little blue macaw
had disappeared. Then an expedition spotted it right where the species
had always been seen, a few miles along a rough dirt road outside
this town 1,300 miles north of Rio de Janeiro.
The
celebrated sighting created a sense of urgency that there was still
a chance for the macaw to teach others of its kind its particular
secrets of surviving: what seeds to eat, what animals to avoid,
where to find food during drought.
The
Permanent Committee for the Recovery of the Spix's Macaw -- formed
the previous year by ornithologists and Spix's owners in Spain,
the Philippines, Switzerland and Brazil to breed the rare birds
in captivity -- took on the new mission of finding the last wild
Spix's a mate.
They
knew they had to act fast. Biologists figure the blue macaw is about
14 years old, and while its breed has lived twice as long in captivity,
those birds don't face the dangers and demands of the wild.
But
there were wrinkles in their efforts. The little blue macaw already
had a steady companion: a slightly smaller Iliger's Macaw, known
here as a maracana.
Exceptional
chivalry
The last Spix's became known for his exceptional chivalry. He would
pick up his companion every morning in her favorite "dormitory
tree," fly with her to scrounge for seeds and, come sunset,
drop her off back home before flying to his protected bachelor pad
in the middle of a cactus.
During
the breeding season, from December to March, the Spix's and the
Iliger nested together, but as far as scientists could tell, the
odd couple's eggs were always infertile.
Still,
there was a question of whether the little blue macaw would turn
from his longtime companion to a bird of his feather. A female Spix's
was chosen based on her chances of surviving in the wild. She had
been caught as an adult, but hadn't eaten local seeds or flown long
distances in years.
After
intensive training, she was deemed fit to be released in March 1995.
They soon found each other and began to fly together, escorted by
the maracana. Meanwhile, the committee went to work whipping up
local support, hoping to discourage drought-punished goatherds from
hunting down the lone macaw to sell to traffickers.
Besides
spreading his sympathetic story, staff members built a Little Macaw
rural schoolhouse, paid an agronomist to train farmers and fenced
goat pastures.
Portraits
and poems
The goodwill campaign has been a great success. Local children and
even some of their parents draw the bird's portrait and write poems
in its praise.
The
experiment with the female Spix's proved a disappointment, however.
She disappeared after just seven weeks. Only last month did de Melo
hear of her fate. A farmer had seen her dead on the ground in 1995,
the likely victim of an electrical transmission wire. "He didn't
say anything for years because he feared the project would end,"
de Melo said.
Now
committee members are cautiously hopeful about a breakthrough in
a field experiment.
Last
December, de Melo had replaced the infertile eggs in the nest shared
by the blue macaw and the maracana with wild Iliger's Macaw fledglings.
The pair accepted them, feeding them and teaching them to fly. Three
months later, the young maracanas left the nest on their own.
Now
the committee is contemplating putting fledgling Spix's macaws born
in captivity into the maracana's nest, a risk previously unthinkable
in view of their limited numbers. The details will be worked out
at a meeting next month in Houston, with the plan to be carried
out after the breeding season starts in December.
De
Melo, who is leaving Curaca in January, dreams of returning someday
to see families of little blue macaws flying wild through the caatinga.
