Green-naped Tanager (Tangara fucosa): Revise global status?

  1. New distribution maps using the method described in Huang, et al. (2021, Batch-produced, GIS-informed range maps for birds based on provenanced, crowd-sourced data inform conservation assessments, PLoS ONE 16(11): e0259299. https://doi.org/10.1371/journal.pone.0259299) suggest the range of this species is somewhat smaller than the previously published map or the proposed new map in Annex 2, above. this suggests that the actual population may be near the lower end of the population estimate of 1,300 – 16,000 given above.

    Although this does not invalidate the downlisting from NT to LC, it should be carefully considered if this downlisting should proceed.

  2. The species is on the Songbirds in Trade Database (SiTDB) watchlist but currently there is no evidence of domestic or international trade targeting this species in the past 15 years.

  3. Many thanks to everyone who has contributed to this discussion. We greatly appreciate the time and effort invested by so many people in commenting. The window for consultation is now closed and we are unable to accept any more comments until 21 February 2022. We will now analyse and interpret the new information, and we will post a preliminary decision on this species’s Red List status on this page on 21 February 2022, when discussions will re-open.

  4. Preliminary proposal

    This species is restricted to a very small range, and a direct quantification of the population size is lacking. The population density of congeners varies considerably, and consequently the inferred population size band of Green-naped Tanager is very coarse. However, as this species is described as ‘fairly common’ and available evidence suggests that it does not occur at low densities, we therefore tentatively assume that the actual population size is in fact closer to the upper end of the band.

    Based on available information, our preliminary proposal for the 2022.1 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 27 February 2022, after which the recommended categorisations will be put forward to IUCN.

    The final 2022.1 Red List categories will be published on the BirdLife and IUCN websites in July 2022, following further checking of information relevant to the assessments by both BirdLife and IUCN.

  6. Recommended categorisation to be put forward to IUCN

    The final categorisation for this species has not changed, but the account for this species has been updated to incorporate additional information from this discussion. Green-naped Tanager is recommended to be listed as Least Concern.

    Many thanks for everyone who contributed to the 2022.1 GTB Forum process. The final 2022.1 Red List categories will be published on the BirdLife and IUCN websites in July 2022, following further checking of information relevant to the assessments by both BirdLife and IUCN.
