In the Brazilian fauna national extinction risk assessment carried out in 2018, the species was categorized as Vulnerable, by the A2c criterion.

Criterion A – The population density of this species varies within its range, and it is a common psittacid in more preserved regions, where groups of 6 to 12 individuals can often be seen during the day. It is considered uncommon and even rare in more degraded and deforested regions, like in the eastern region of Pará, where it was more common in the past. There are no population studies done with this species, but using statistics and modeling of habitat loss due to deforestation, it is possible to infer that there has been a population decline of at least 30% in the last three generations (21 years) and that there will be a decline between 37 and 54% in the next three generations (Bird et al., 2012).
Note: Now in 2022 we understand that there are better remote sensing data that allow for a better characterisation of habitat loss. In addition, by using the new Bird et al. (2020) reference for generation time, the time window will be smaller and will change the habitat loss values for the species. In this sense, I believe that in 2022 the species can be characterised as Least Concern (LC) for this criterion.
Criterion B – The EOO calculations (886,244 km2) do not meet the thresholds for categorisation as threatened. Its AOO (greater than 2,000 km2), does not meet the thresholds for threatened categorisation. Least Concern (LC) for this criterion.
Criterion C – No information is available on population estimates. Also at the time of assessment (2018) no observed, estimated, projected or inferred population decline data was available. Only suspected data of the decline. Thus, IUCN criterion C is not applicable. Least Concern (LC) for this criterion.
Criterion D – No information on population estimates available. Least Concern (LC) for this criterion.
Criterion E – in the assessment conducted in 2018, we found no PVA data.

Many thanks to everyone who has contributed to this discussion. We greatly appreciate the time and effort invested by so many people in commenting. The window for consultation is now closed and we are unable to accept any more comments until 21 February 2022. We will now analyse and interpret the new information, and we will post a preliminary decision on this species’s Red List status on this page on 21 February 2022, when discussions will re-open.
Based on available information, our preliminary proposal for the 2022.1 Red List would be to adopt the proposed classifications outlined in the initial forum discussion.
There is now a period for further comments until the final deadline on 27 February 2022, after which the recommended categorisations will be put forward to IUCN.
The final 2022.1 Red List categories will be published on the BirdLife and IUCN websites in July 2022, following further checking of information relevant to the assessments by both BirdLife and IUCN.

Recommended categorisation to be put forward to IUCN
The final categorisation for this species has not changed, but the account for this species has been updated to incorporate additional information from this discussion. Vulturine Parrot is recommended to be listed as Least Concern.

I agree with LC, habitat loss rates for this species have even been overestimated in the past.
