| 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... |

| Neotropical parrots are among the most threatened groups of birds in the world, and many species are facing extinction in a near future. At the same time, the taxonomic position of many species remains unclear. Karyotype analysis has been used to elucidate the phylogenetic status of many bird groups, also providing important information for both in situ and ex situ conservation plans. The objective of the present study was to describe for the first time the karyotypes of the endangered Hyacinth Macaw, Anodorhynchus hyacinthinus, and of the Hawk-headed Parrot, Deroptyus accipitrinus. A diploid number of 2n = 70 and a karyotype similar to the main pattern previously found for the genera Ara, Cyanopsitta, Aratinga, Propyrrhura, Pionites, Pionopsitta,... |
