Yes, I agree with the proposal to change the status of this species to Critically Endangered.
Based on surveys conducted by BISA Indonesia in 2024 and 2025 targeting the species Black-winged Myna, Javan Blue Flycatcher, Larwo Shama, Javan Leafbird, and Greater Leafbird in Alas Purwo National Park, we never recorded any individuals of Larwo Shama in the park. This is concerning, as we believe that the highest remaining population of Larwo Shama was most likely in Alas Purwo.
In addition, we conducted interviews with people in the buffer villages around the national park who work as bird hunters in Alas Purwo. They stated that this species has become extremely difficult to find. In 2024, according to the hunters we interviewed, only one individual was captured (with no photo evidence).
Based on burungnesia data submitted by our users, there was only one recorded Larwo in Alas Purwo in May 2020, totaling one bird. Coordinates -8.7xx; 114.3xx. Reported by Gendut Hariyanto, an Alas Purwo Ranger, who I believe has excellent field identification skills. Previously, in 2018, one bird was found not far from my location by my self. This was a visual encounter. As of today, my team and I are annotating recordings from bioacoustic recordings installed throughout 2023 throughout the TNAP area. Only one grid (3×3 km) has been annotated. We have found one suspected Larwo call, located not far from the locations of previous encounters.
FYI, we already have 700GB of bioacoustic sounds from the entire Alas Purwo area (divided into a 3×3 km grid). We are currently collecting master Larwo sounds from PCBA Prigen to train machine learning. From here, we will detect Larwo’s possible whereabouts from his voice recordings. I hope that by the end of this month, we will have a preliminary information of Larwo’s status in Alas Purwo.
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 2 February 2026. We will now analyse and interpret the information, and we will post a preliminary decision on this species’ Red List category on this page on 2 February 2026, when discussions will re-open.
We thank contributors for their comments; these data make even clearer that any extant population of Larwo Shama must now be tiny. These comments will be incorporated into the assessment. Based on available information, our preliminary proposal for the 2026 Red List would be to adopt the proposed classification outlined in the initial forum discussion.
There is now a period for further comments until the final deadline on 8 February 2026, after which the recommended categorisations will be put forward to IUCN.
The final 2026 Red List categories will be published on the BirdLife and IUCN websites later this year, 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. Larwo Shama is recommended to be listed as Critically Endangered under Criteria C2a(i); D.
