In California, USA
Tomales Bay = stable
Wintering Marbled Godwits at Tomales Bay, whose numbers have remained stable, consist of two races, Limosa fedoa fedoa and L. f. beringiae. The latter breeds in Alaska, numbering around 2,000 birds, and the former breeds in the Great Plains of North America, numbering around 170,000 birds (Gibson and Kessel 1989, Andres et al. 2012, Ruthrauff et al. 2019). Marbled Godwit populations at Tomales Bay have remained stable, and recent BBS data (1989-2017) indicate increasing breeding populations of L. f . fedoa in the US but decreasing populations in Canada (Pardieck et al. 2018).

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.

Recommended categorisation to be put forward to IUCN
The final categorisation for this species has not changed. Marbled Godwit is recommended to be listed as Vulnerable under Criteria A2bc+4bc.
