Timor Green Pigeon (Treron psittaceus) – 2026
On 2026 at 08:22 hrs, I recorded three Timor Green Pigeons (Treron psittaceus) at Aubeon, Natarbora (Manatuto–Manufahi coastal corridor), Timor-Leste. The birds were observed flying from a mangrove–lagoon edge, briefly landing in a Casuarina stand for 3–4 minutes, before moving toward the Barique–Viqueque direction. Identification was based on direct field observation of morphology and flight behaviour consistent with the species.
The site is a fragmented coastal wetland–mangrove and lowland forest mosaic, with limited disturbance in some areas and surrounding forest that remains poorly surveyed and difficult to access.
This record provides recent confirmed evidence of T. psittaceus outside its main stronghold in Lautem District, where most modern records are concentrated. It supports the interpretation that the species persists in highly fragmented, very low-density subpopulations along the south coast, using coastal forest and mangrove systems as movement or foraging habitat.
A preliminary, unverified estimate of 20–40 individuals is suggested for the wider Natarbora–Manufahi–Barique corridor, but this is strictly hypothetical and requires systematic survey confirmation.
Given ongoing habitat loss and very low encounter rates across its range, this observation highlights the need for urgent targeted surveys in the south-coastal lowland forests of Timor-Leste.
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 22 May 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 22 May 2026, when discussions will re-open.
Based on available information, our preliminary proposal for the 2026 Red List would be to adopt the proposed classifications outlined in the initial forum discussion. The map has been edited to extend the resident extant range further along the south coast to incorporate recent records.
There is now a period for further comments until the final deadline on 31 May 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 in November 2026, following further checking of information relevant to the assessments by both BirdLife and IUCN.

During opportunistic surveys, including birdwatching trips conducted between 2019 and 2025, we failed to detect the species on Rote Island.
