| Population justification: This species is described as uncommon and probably declining. Its population is estimated to number at least 10,000 individuals in total (surely runs into five figures), roughly equivalent to 6,700 mature individuals. Since 2000, declines have continued in Ecuador (c.65 birds in five disjunct populations remain [R. Williams in litt. 2002]), Peru and Bolivia, but it remains numerous and appears to be stable in northern Argentina (M. Pearman in litt. 2003). The largest known population is in north-west Patagonia and comprises an estimated c.300 individuals of which c.200 are adults (Lambertucci 2010). Populations in Venezuela (<30 individuals [Cuesta and Sulbaran 2000], or fewer [Sharpe et al. 2008]) and Colombia may be maintained by reintroduction and feeding, but in Colombia at least the population may still be declining. The status of remaining populations is difficult to determine because its mortality, breeding frequency and success are so poorly known (Houston 1994). | ||||
| Trend justification: A moderately rapid and on-going decline is suspected, owing to levels of persecution by humans. | ||||
