Tucumán Amazon Amazona tucumana is restricted to the southern Yungas mountains from south-eastern Bolivia to north-western Argentina. It is currently classified as Near Threatened as its population is suspected to be declining moderately rapidly owing to habitat loss and capture for the cagebird trade. Rivera et al. (2009) detail recent population estimates and numbers captured for trade in Bolivia. Surveys of 18 sites in Bolivia in 2006-2007 recorded a total of 1,643 individuals, and c5,400 birds were reportedly captured legally during 1981-1983, prior to the listing of the species on CITES Appendix 1. The population has not recovered to former levels, and capture for local trade continues but on a reduced scale. Argentina is thought to hold around 75 % of the global population, and capture for international trade there reached an estimated peak of 20,000 around 1980.

Habitat loss and degradation owing to industrial timber extraction, slash-and-burn agriculture (even in protected areas) and the illegal pet trade remain key critical factors in Bolivia. Forest loss and degradation are also the most critical factors affecting the Argentinean population (Rivera et al. 2009).

If it is reasonable to suspect that the population has decreased by 30-49 % over a period of 37 years (three generations – BirdLife International unpubl. Data) i.e. 1974-2011, then the species should be uplisted to Vulnerable under the A criterion. Comments on this proposal are welcomed.

    Our research shows that Amazona tucumana has declined dramatically during the last 30 years. Although international agreements are in place national and provincial governments have not taken action to protect the species. Particularly it is necessary to halt forest transformation and degradation since the main nesting and feeding tree species (e.g., Podocarpus parlatorei, Juglans australis) are also those most logged by timber activities (Rivera unpublished). Furthermore, the species is not frequently observed as it used to be previous to the 70s, especially in the southern range of its distribution in Argentina (i.e., Tucuman and Catamarca provinces). In Bolivia the species has been recently categorized as Vulnerable (Rojas et al. 2009) and in Argentina as Threatened (López Lanus et al. 2008). The information gathered through an exhaustive literature review, on trade and capture data, and our surveys can be used to assess adequately the species status as vulnerable (Rivera et al. 2007, 2010).
