7 thoughts on “Hudsonian Godwit (Limosa haemastica)”
Dear committee,
We wish to provide additional information on population size and threats to the Hudsonian Godwit in Chile, as a joint contribution from Centro Bahía Lomas of the Universidad Santo Tomás and the NGO Red de Observadores de Aves y Vida Silvestre de Chile (ROC). Considering the threats described below, we agree with the proposed change of the species classification to ‘Vulnerable’.
Population size: Based on an aerial census of the entire Bahía Lomas shoreline, our most recent estimate of the wintering population of Hudsonian Godwit is 24,038 ± 148 individuals during January 2023 (Norambuena et al. 2023). According to our aerial surveys in Bahía Lomas over the last 10 year, the population that spend their non-breeding season at this site appear to be stable, fluctuation between 11.000 and 24.000 individuals over this period (Norambuena et al. 2023).
Threats: The population in Bahía Lomas and Tierra del Fuego has recently been threatened by the massive expansion of wind farms to feed the new green hydrogen industry, which according to government planning will produce 25GB of wind energy in Magallanes. This is equivalent to 2900 turbines of 3 MW each (Norambuena et al. 2021). The potential for increased mortality due to collisions remains unknown, but given the scale of the proposed development, it poses a significant threat to the stability of the population. Other threats in the area include spill risks from nearby oil platforms (active and inactive) and spills from oil wells, pipelines, storage facilities, and compressors located in Bahía Lomas (Espoz et al. 2022).

We received the following contribution from Pete Davidson:
Lesser Yellowlegs and Hudsonian Godwit look solid too. Just one wee typo to correct: note the acronym is COSEWIC (not COSIEWIC, as appears in both the Lesser Yellowlegs and Hudsonian Godwit accounts).
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.
There are few records of occurrence in the Pantanal, most of them linked to environments such as salinas, habitats especially found in the Nhecolândia region. Climate change and eutrophication of salinas due to excessive use of cattle may impact the species’ wintering sites in the Pantanal

Recommended categorisation to be put forward to IUCN
The final categorisation for this species has not changed. Hudsonian Godwit is recommended to be listed as Vulnerable under Criteria A2bc+4bc. There is now evidence that conversion and degradation of habitat is contributing the rate of reduction, hence subcriterion c has been added to the assessment.
Many thanks for everyone who contributed to the 2024.2 GTB Forum process. 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.
