6 thoughts on “Blue-bellied Parrot (Triclaria malachitacea): Revise global status?”
The proposal to downlist this Brazilian endemic species from NT to LC seems reasonable. It is not listed as threatened or Near Threatened in the Brazilian National Red List.
New distribution maps using the method described in Huang, et al. (2021, Batch-produced, GIS-informed range maps for birds based on provenanced, crowd-sourced data inform conservation assessments, PLoS ONE 16(11): e0259299. https://doi.org/10.1371/journal.pone.0259299) suggest the range of this species is slightly larger than the previous assessment. Huang et al. find the Area of Habitat (AoH) to be 47,636 km2; the area of the previously published range map was 30,243 km2, meaning the new range map is 158% the size of the previous map. Part of the increase is greater range in Rio Grtande do Sul, Santa Catarina, and Paraná states.
Prior to this assessment, no population estimate was provided. Given that the likely range size is larger than previously used, the population estimate is likely larger than would have been previously assessed. This supports the proposed downlisting of the species from NT to LC under the application of IUCN Red List Criteria in Annex 2.
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. Blue-bellied Parrotlet is recommended to be listed as Least Concern.
