Resumen:
Psittaciformes (parrots, cockatoos) are among the most endangered birds, with 31% ofNeotropical species under threat. The drivers of this situation appear to be manifold andmainly of anthropogenic origin. However, this assessment is based on the last extensiveconsultation about the conservation situation of parrots carried out in the 1990s. Giventhe rapid development of anthropogenic threats, updated data are needed to strategizeconservation actions. Using a population approach, we addressed this need through a168wide-ranging consultation involving biologists, wildlife managers, government agenciesand non-governmental conservation organizations. We gathered up-to-dateinformation on threats affecting 192 populations of 96 Neotropical parrot species across21 countries. Moreover, we investigated associations among current threats andpopulation trends. Many populations were affected by multiple threats. Agriculture,capture for the pet trade, and logging each affected >55% of the populations, suggestinga higher degree of risk than previously thought. In contrast to previous studies at thespecies level, our study showed that the threat most closely associated with decreasingpopulation trends is now capture for the domestic pet trade. Other threats associatedwith decreasing populations include small-holder farming, rural populationpressure, nest destruction by poachers, agro-industry grazing, small-holder grazing, andcapture for the international pet trade. Conservation actions have been implementedon <20% of populations. Our results highlight the importance of a population levelapproach in revealing the extent of threats to wild populations. It is critical to increasethe scope of conservation actions to reduce the capture of wild parrots for pets
