PRISM surveys in the Arctic National Wildlife Refuge, Alaska between 2002/2004 and 2019/2022 showed a decrease (2002/2004: 6,218, SE=2,194; 2019/2022: 4,324, SE = 1,469). A similar survey in the Teshekpuk Lake Special Area in north central Alaska showed a slight increase in number of individuals detected in 2007/2008 (23) to 2023 (30). We plan to do another year of surveys in this area before generating population estimates that can be used to evaluate population-level wide change in this location. (S. Brown and R.

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 3 May 2024. We will now analyse and interpret all information, and we will post a preliminary decision on this species’ Red List status on this page on 3 May 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.
There is now a period for further comments until the final deadline on 13 May 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 October 2024, following further checking of information relevant to the assessments by both BirdLife and IUCN.
It is among the most numerous nearctic migrants in the sub-region Nhecolândia Pantanal, where it occurs almost exclusively in wet meadows and salinas. These wintering sites are under threat due to the replacement of native pastures by exotic grasses, climate change (extreme droughts) and changes in the flooding regime due to the waterway project on the Paraguay River
It seems Colombia is not a wintering ground for this shorebird, there are some stop over sites along the Caribbean, Llanos, Andes and the Pacific coast (https://www.researchgate.net/publication/358967124_Notable_records_of_migratory_shorebirds_from_the_Caribbean_coast_of_Colombia). So it is necessary to check the map to show the passage áreas in South America.
