Habitat loss and trapping for the cage-bird trade are the most significant threats to the red-tailed Amazon (4). Poaching by native Indians and for national and (illegal) international trade is placing the species under enormous pressure (6). Of 47 nests monitored between 1990 and 1994, six were naturally predated and the other 41 exploited by humans. Not only does this reduce the number of wild individuals, but nest cavities are also frequently damaged in the process of removing nestlings, reducing the number of nests available (4). Boat building, banana plantations, cattle and buffalo grazing and the construction of beach houses is causing the rapid loss of most remaining lowland forest (2) (4). It is feared that the proposed construction of a bridge to Ilha Comprida will increase pressure from tourism and habitat conversion (4).
The red-tailed Amazon is protected under Brazilian law and occurs in 15 protected areas, but law enforcement is often lacking (4). Its listing on CITES Appendix I prohibits international trade in this species, but illegal smuggling nevertheless continues. Many die painfully during the journey from hunger, thirst, broken limbs, or simply from trauma (5). Several projects have been implemented to raise local awareness about the threats facing this rare bird, and seem to have had some success. Successful captive breeding programmes are run in Brazil and Europe and studbooks are maintained to help keep captive populations genetically healthy (4).
