5 thoughts on “Siberian Sandplover (Charadrius mongolus)”
Bakewell’s paper is mentioned in the text but not the references: the citation should be Bakewell, D.N. 2022. Identification of Siberian Charadrius (mongolus) mongolus and Tibetan C. (m.) atrifrons Sand Plovers. Birding Asia 38: 23-35.
I think the flyway population estimate is too low. It assumes that all Siberian Sand Plovers migrate to Australia. However, I think some only migrate as far as Indonesia and New Guinea, judging by photos on eBird taken between November and February; they include classic Siberians as far west as Timor. In PNG, Bishop (2006) noted that that Lesser Sand Plovers and widespread and common winter visitors; photos on ebird suggest that Siberians dominate there.
I think you should mention the low level of certainty about the population of Siberian Sand Plovers. In addition to the scanty knowledge of numbers in New Guinea and Indonesia, it is difficult to count due to identification challenges, and also because its distribution can be quite patchy: e.g. in 60% of the population in north-western Australia occurs on Adele Island, a small island within a very large area (Rogers et al. 2011): Rogers, D.I., C.J. Hassell, A. Boyle, K. Gosbell, C. Minton, K.G. Rogers and R.H. Clarke. 2011. Shorebirds of the Kimberley Coast – Populations, key sites, trends and threats.

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 26 June 2023. We will now analyse and interpret the new information, and we will post a preliminary decision on this species’ Red List status on this page on 26 June 2023, when discussions will re-open.
Based on available information, our preliminary proposal for the 2023 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 2 July 2023, after which the recommended categorisations will be put forward to IUCN.
The final 2023 Red List categories will be published on the BirdLife and IUCN websites in December 2023, 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. Siberian Sandplover is recommended to be listed as Endangered under Criteria A2bce+4bce.
