I agree with this decision. As highlighted in the text, this is a poorly-known, cryptic species that is hard to study, although there are two broad reasons to believe this species is unlikely to be at conservation risk. These are already succinctly summarized in the text, but in brief: 1) The species occurs widely across Sulawesi, and this range is even larger than previously thought, given recently identified range extensions on the islands of South-east Sulawesi. 2) The species does not seem to be particularly forest-dependent, and hence is probably not at serious risk from habitat loss and habitat degradation. It was encountered more frequently in edge-forest and non-forest habitats (including villages, occassionally), than interior forest habitats during long-running surveywork on Buton island (no doubt a product of detection bias, but still highlighting that this species does utilize non-forest habitats) (Martin et al. 2012). Observations of this species on Kabaena and Wawonii Islands were also exclusively in non-forest or forest edge habitats (O’Connell et al. 2017; 2019). Finally, as far as I am aware, there is no evidence of significant impacts on this species from threats other than habitat loss (e.g. trapping for the cage bird trade).
Agree with Thomas Martin, this species clearly not particularly forest-dependent with said evidence and possibly also underreported due to detection bias and confusion with Sulawesi Hanging-Parrot. A possible breeding attempt was observed using a hollow utility pole next to a busy road in the middle of a village in Buton (pers. obs), which may further prove its tolerance to a modified rural habitat to a certain degree.
Other than a reported case of 2131 individuals being traded in 1991 (Collar et al. 2020) and a possible escapee from birds market observed in Jakarta in 2018 (Atlas Burung Indonesia 2020), there are no evidence of threats from trapping/trading.
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. We will analyse and interpret the new information and post a preliminary decision on this species’s Red List status on this page in early July.
Thank you once again,
BirdLife Red List Team
Based on available information, our preliminary proposal for the 2021 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 in mid-July, after which the recommended categorisations will be put forward to IUCN.
The final 2021 Red List categories will be published on the BirdLife and IUCN websites in December 2021, 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. Pygmy Hanging-parrot is recommended to be listed as Least Concern.
Many thanks for everyone who contributed to the 2021 GTB Forum process. The final 2021 Red List categories will be published on the BirdLife and IUCN websites in December 2021, following further checking of information relevant to the assessments by both BirdLife and IUCN.
