Population justification: Preliminary population estimates best place the global population in the band 10,000-19,999 individuals (S. Koenig in litt. 2008). This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals. Further studies are required to obtain an accurate figure.

Trend justification: The species is undergoing a rapid decline at an accelerating rate, which is projected to continue over the next decades (Koenig 2008). This decline is caused by moderate rates of tree cover loss (Koenig 2008, Global Forest Watch 2020), deterioration of habitat quality due to a higher frequency of droughts, increased risk of hybridisation with Puerto Rican Amazon Amazona vittata, an increase in invasive nest predators, and hunting for the local pet trade (L. Gibson in litt. 2020, Cawley et al. 2020, Gibson 2020). The rate of decline is projected at 50-79% over three generations (31.8 years).
