It is ironic that in the country named after the Brazilian
Hardwood tree (Caesalpinia echimatta), that the species nearly went extinct
before measures were taken for its rescue. If current trends continue,
such a hapless fate could befall another Brazilian species, the beautiful
Golden Conure (Guaruba guarouba). With its yellow and green markings,
the country's national colors, this popular parrot's habitat is being ravaged
in a region currently weathering the bulk of Amazon rainforest destruction.
Accentuating the bird's plight is its rapacious trapping by smugglers who
feed the illicit market demand this species still creates. This parrot's
future in the wild is at best precarious; it will require courageous and
innovative conservation efforts to ensure that at least some bands are
able to continue to live and prosper in their natural habitat.

The rural social conditions spawned by this boom-bust cycle of timber
tend to be abominable, presenting a further obstacle in the bird's struggle
to survive. A group of the birds were encountered near a community of "sem-terras",
landless peasants who receive plots to farm through a controversial government
agrarian reform program. Completely isolated and neglected, the hygienic
conditions were so dreadful that malaria had permeated the community. It
was simply good fortune that none of Yamashita's team contracted any grave
illnesses.
During the period of study, Dr. Yamashita located 13 nesting snags within
a 90 kilometer radius of Paragominas, all of them located in cleared areas
either next to or at maximum of 3 kilometers from intact rainforest patches.
This does not mean that cleared areas are able to sustain populations of
Golden Conures; merely that many of the forest patches nearby have been
selectively logged and therefore lack snags large enough to support the
birds. These snags in open areas are much more vulnerable to winds and
often will topple, causing the birds to seek other suitable nesting sites
and exposing the flocks to further dangers. In addition, the fact that
these snags are not within the protective labyrinth of the forest facilitates
the work of the local trappers.
A fascinating aspect of the Conure's behavior is the presence of "helpers"

Given the dearth of information on the bird's
behavioral and reproductive patterns, the World Parrot Trust resolved to
fund new research, spear-headed by one of Brazil's premier parrot experts,
Dr. Carlos Yamashita. In his two months of research, based out of Paragominas,
Para, Dr. Yamashita set out to identify and map nesting trees (or snags),
observe and document group behavior, and analyze blood samples to determine
the degree of relatedness among members of bands (small flocks) identified
in specific snags.
The range of Golden Conures extends far westward into the Amazon basin
reaching all the way to the right bank of the Madeira Rio in Amazonas state;
the bird reaches as far east as the Gurupi in Maranhao state. It is found
in much higher density (almost ten times) within the confines of the study
area. This coincides almost directly with the heaviest deforestation zones.
Devastated
landscape
The town of Paragominas, at the heart of the
region, is now surrounded by
a devastated landscape. Over the
past several years, two thirds of the town's lumber mills have ceased to
operate, indicating an exhaustion of
local wood sources. This means
