Disagree on downlisting to NT.
Altough current knowledge of its distribution that its range extend far from originally thought, recent records from western part of its range is very limited. Other than described by Marsden (2023), some record from the West of Lawu were only (CMIIW): Gunung Gede in 2017 (Scott Robinson in eBird), Gunung Slamet in 2013 (John Mittermeier, also in eBird), Gunung Slamet in 2018 (Devenish et al, 2022), and Pekalongan in 2022 (Ahmadin and Taufiqurrahman pers. comm). All of this area is in isolated mountain, and I do not think there are suitable lowland forest in the region suitable for this species.
Most of the recent observation were still from Eastern Java and Bali (230 from eBird, 64 from Burungnesia). Most of this observation were reported from Baluran, Bali Barat, Bedugul and Ijen; which may have the biggest subpopulation, with few repeated report from Bromo Tengger Semeru and Lawu, and even fewer from southern coast of Malang (Kondang Merak). Moreover during island-wide event Big Month 2020 (Squires et al, 2020)–which were focused outside of conservation area–the species were only reported from four location all from East Java (which has the most coverage visit during the event). My point is that while the range seems to be wider than expected before, the population is very fragmented as explained in this proposal, with main population limited only in the area where the species is originally believed to exist.
One undiscussed thread that may affect the lowland population is the development of Java’s southern coast which may affect (if not already) subpopulation on the southern coast of East Java, especially in Kondang Merak.
Many thanks to everyone who has contributed to this discussion. We greatly appreciate the time and effort invested in commenting. The window for consultation is now closed and we are unable to accept any more comments until 12 February 2024. We will now analyse and interpret the information, and we will post a preliminary decision on this species’ Red List status on this page on 12 February 2024, when discussions will re-open.
Based on available information, our preliminary proposal for the 2024 Red List would be to adopt the proposed classifications outlined in the initial forum discussion. We thank Panji Gusti Akbar for his comment. However, while the number of records from the west is limited, it still greatly reduces the extinction risk of this species. Moreover, in the east, sizeable populations are in protected areas (including Bali Barat and Baluran) with no indication that in these areas it is declining. Locally this species is almost certainly declining (including on Kangean, and the development mentioned by P. G. Akbar has now been added as a second example of where the species might be declining). However, notwithstanding these points, this species’ population size is not very small, and the risk of extinction is spread across multiple subpopulations with no evidence it meets the thresholds for listing as threatened presently.
There is now a period for further comments until the final deadline on 18 February 2024, after which the recommended categorisations will be put forward to IUCN.
The final 2024 Red List categories will be published on the BirdLife and IUCN websites in December 2024, 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. Javan Flameback is recommended to be listed as Near Threatened, approaching the thresholds for listing as threatened under Criterion C2a(i).
Many thanks for everyone who contributed to the 2024.1 GTB Forum process. The final 2024 Red List categories will now be published on the BirdLife and IUCN websites in October 2024, following further checking of information relevant to the assessments by both BirdLife and IUCN.
