I do not much agree with this proposal, for a species which is now and recently locally extinct in most of the map that is presented here.
The species does not seem to occur west of the Andes anymore, or in the Colombian Perija. It is found in Tama, which is supposedly under deforestation and hunting pressure, and in Venezuela. It may be worth comparing maps on ebird with yours, to see how rare this species now is. Renjifo et al’s assessment is in my view accurate for Colombia and presents an alarming picture which should not be glossed over.
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 temporarily closed and we are unable to accept any more comments until 6 February 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 6 February 2023, when discussions will re-open.
Information submitted via this discussion forum highlight the species’ rarity, declines and local extinction. The map as shown here reflects the species’ recent disappearance from previously occupied sites, including the Colombian part of the Sierra de Perijá. Only those areas marked as ‘extant’ are of relevance for the Red List assessment. The updated factsheet strongly relies on the Colombian national Red List assessment; however, as noted in the assessment presented here, the species’ generation length has since been updated, so that the relevant time period for the assessment against Criterion A is now 27 years. As detailed in the assessment topic, all currently available evidence supports population declines in the band of 30-49% over 27 years. While the population size for Colombia is estimated based on observed densities the data for Venezuela is less certain, and as such the level of data quality is insufficient for a threatened status under Criterion C, as specified in IUCN Guidelines.
Therefore, 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 12 February 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. Helmeted Curassow is recommended to be listed as Vulnerable under Criteria A2cd+3cd+4cd.
