5 thoughts on “White-mantled Barbet (Capito hypoleucus)”
It is true that the evidence on which a small population size was originally inferred is shaky, at most, but evidence supporting a much more larger population is neither convincing, nor trustworthy. The species does not meet any criteria to be considered threatened with extinction, but given the absence of solid quantitative information, perhaps a more cautious stance should be taken. For instance, Renjifo et al. (2014) acknowledged that the species AOO (8860 Km2) could be dangerously approaching the VU threshold if the inferred rate of habitat loss should continue (~6.5% in 10 years), which is likely. They do categorize this species (which is endemic to Colombia) as NT, and I recommend to follow this measure until more information is available.

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 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 the Forum support the assessment as non-threatened. Consistently applying IUCN’s categories and criteria indicate that this species does not approach the threshold a threatened status under B2 given that the AOO is too large and while it is declining slowly there is no evidence that it currently meets subcriterion a). It is recognised that the population is in decline and the need for careful monitoring is noted in the species factsheet.
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. White-mantled Barbet is recommended to be listed as Least Concern.
