Lack of evidence for the presence of macaws of the Anodorhynchus genus in the Colombian-Brazilian river basin of the Vaupés

Mostrar todas las versiones(3)

It is generally understood that the Anodorhynchus genus of macaws does not spread north of the Amazon River. However, recent published information suggests that the endangered Hyacinth Macaw Anodorhynchus hyacinthinus may occur in the region of the Papurí River, lower Vaupés, in Amazonian Colombia....

ANODORHYNCHUS ENTREVISTAS BAJO VAUPES ANODORHYNCHUS LOWER VAUPES INTERVIEWS It is generally understood that the Anodorhynchus genus of macaws does not spread north of the Amazon River. However, recent published information suggests that the endangered Hyacinth Macaw Anodorhynchus hyacinthinus may occur in the region of the Papurí River, lower Vaupés, in Amazonian Colombia. This information is hypothetical, based on old reports and observations with imprecise geographical data. Our objective was to confirm the presence of macaws of the genus Anodorhynchus in the lower Vaupés, Colombia, and in nearby Negro River, Brazil. We carried out fieldwork and interviews from September 2004 to July 2005, but we failed to locate the species. Notwithstanding, we received information from 8% of the interviewed members of local ethnic groups suggesting that a macaw with similar characteristics to Anodorhynchus genus could inhabit this area. We discuss about the presence of macaws of this genus north of the Amazon River, and their potential food sources (local palms). On the basis of the absence of recordings we conclude that Anodorhynchus hyacinthinus should be considered hypothetical, at least in Colombia. Nevertheless, we recommend following the precautionary principle and suggest further work in the area. Formalmente, el género Anodorhynchus no se distribuye al norte del río Amazonas, pero información reciente sugiere lo contrario, con la posibilidad de que Anodorhynchus hyacinthinus (especie amenazada) se encuentre presente en la región del río Papurí, en la cuenca inferior del Vaupés (Amazonía colombiana). Sin embargo, esta información es hipotética, se basa en documentos antiguos y observaciones con datos geográficos poco precisos. El objetivo del trabajo fue documentar la existencia de guacamayos del género Anodorhynchus en la cuenca inferior del río Vaupés (Colombia) y en el río Negro (Brasil). Se realizaron salidas de campo y entrevistas desde septiembre de 2004 hasta julio de 2005 pero no se pudo hallar a la especie. No obstante, un bajo porcentaje (8%) de la información obtenida de las etnias locales indicó que un guacamayo con las características del género Anodorhynchus habitaría en el área. Se discute sobre la presencia de guacamayos de este género al norte del río Amazonas y sus posibles fuentes de alimentación (las palmas locales). Ante la falta de registros se concluye que todas las evidencias deben ser consideradas como hipotéticas, al menos en Colombia, aunque aplicando el principio de precaución se justifica encarar una segunda fase del proyecto de búsqueda de la especie en el área.
