Population justification: The population was previously estimated to number 1,000-2,499 individuals, based on an assessment of known records, descriptions of abundance and range size. However, recent information suggests the population may be larger than this. The species has been recorded at several additional locations (Laranjeiras and Cohn-Haft 2009), and a recent survey along the Tapajós river by Laranjeiras (2011) indicated that it was as common in the study area as other, non-threatened Psittacids. The population in this study area (a strip of c.340 km along the Tapajós river, western Pará), which encompasses no more than 5% of the total area of suitable habitat for the species, was estimated at 500 individuals, representing the largest known population. A highly conservative extrapolation of 1 individual per 16 km² across 174,000 km² of suitable habitat within the known Extent of Occurrence gives an estimate of c.10,875 individuals (Laranjeiras 2011). On the basis of this information, the population is placed in the band for 10,000-19,999 individuals, assumed to include c.6,600-13,400 mature individuals.

Trend justification: This species is suspected to lose 23.3-30.9% of suitable habitat within its distribution over three generations (22 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). Given the susceptibility of the species to hunting and/or trapping, it is therefore suspected to decline by ≥30% over the next three generations. It should be noted, however, that this may be rather precautionary, as trapping of this species for trade (although extensive in the past) is no longer thought to have a significant impact on the wild population (L. F. Silveira in litt. 2012, A. C. Lees in litt. 2013). In addition, its level of forest-dependence is regarded as not as high as some non-threatened Psittacids in the region (A. C. Lees in litt. 2013).
