6 thoughts on “Nilgiri Woodpigeon (Columba elphinstonii)”
With climate change effect being visible in the form of increase in degradation mainly in the form of landslides, all these loss of forest cover need to be considered, which can happen in small to large patches, and can happen inside a PA also. So unless the latest forest loss pertaining to the habitat of this species is considered, it is not advisable to move this species from Vulnerable to Near threatened. More over being an endemic it is already restricted to a specific habitat type, area, landscape and region, so without knowing or having a proper status of the species and habitat my opinion is to retain it as vulnerable. In my opinion the data is insufficient to categorize it as Near Threatened.
In addition to what is already mentioned, the current annual trend in Woodland is also estimated to be stable (similar to national trend) https://stateofindiasbirds.in/species/wdl-niwpig1/. The only state where some trend is available is from Kerala, where the long-term trend is estimated to be stable. https://stateofindiasbirds.in/species/kl-niwpig1/ – Though current trends appear to be mostly stable, since a historical decline can be inferred or suspected, perhaps over a period of 3 generations (12 years), it seem prudent to verify the rate of decline in 3 generations. Solely using the most optimistic bound from SoIB national trends (30%) decline in 30 years (against pre-2000 baseline with median year 1993), it would provide a decline of about 13% in 12 years, admittedly, not qualifying Near Threatened (20-29%).
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 28 October 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 28 October 2024, when discussions will re-open.
Based on available information, our preliminary proposal for the 2025 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 10 November 2024, after which the recommended categorisations will be put forward to IUCN.
The final Red List categories will be published on the BirdLife and IUCN websites in 2025, 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. Nilgiri Woodpigeon is recommended to be listed as Least Concern.
