Archived 2017 topics: White-winged Cotinga (Xipholena atropurpurea): downlist from Endangered to Vulnerable?

This discussion was first published as part of the 2016 Red List update. At the time a decision regarding its status was pended, but to enable potential reassessment of this species as part of the 2017 Red List update this post remained open and the date of posting was updated.

BirdLife species factsheet for White-winged Cotinga

White-winged Cotinga is endemic to eastern Brazil, where it is now virtually confined to 13 protected areas. The species is currently listed as Endangered under B1ab(i,ii,iii,iv,v). The Extent of Occurrence (EOO) was estimated at 1,800 km2 within which the range was believed to be severely fragmented, however revisions to the method for calculating EOO result in a new estimate of 250,000 km2. The population is estimated to be 3,400-13,000 mature individuals and a rapid and on-going population decline is suspected based on rates of habitat loss.

In the Brazilian Red List assessment for birds (MMA 2014) this species is listed as Vulnerable under C2a(i). The total population is estimated at <10,000 mature individuals with each subpopulation containing <1,000 mature individuals. The population is in continuing decline, with no recent records from Rio de Janeiro and the species in a serious condition in the Pernambuco Center of Endemism. The species’s assessment on the Brazilian Red List can be accessed here.

Revisions to the guidance on estimating EOO mean that the species no longer approaches the thresholds for listing under criterion B1. Following the national assessment would result in a downlisting of its global status to Vulnerable under criterion C2a(i).

Comments on the proposed downlisting are welcome.

  1. Bennett Hennessey says:

    I have spoken to over 5 Brazilian ornithologists with experience in the Atlantic Forest, who all confirmed that the 2015 listing of Xipholena atropurpurea, White-winged Cotinga and Cotinga maculata, Banded Cotinga was very inaccurate as White-winged Cotinga was four times more common than Banded Cotinga. Banded has disappeared from known sites.
    WikiAves has evidence of the White-winged Cotinga occuring in 5 states in 20 sites (209 photos), where as Banded Cotinga has evidence in 1 state (Bahia) in 5 sites (87 photos- the majority from two sites).
    With species in the Brazilian Atlantic Forest it is important to calculate their area of occupancy (AOO). It would be great if someone could work out the area from the most recent data.

  2. James Westrip (BirdLife) says:

    Based on available information, our proposal for the 2016 Red List would be to pend the decision on this species and keep this discussion open until 2017, while leaving the current Red List category unchanged in the 2016 update.

    Final 2016 Red List categories will be published on the BirdLife and IUCN websites in early December, following further checking of information relevant to the assessments by both BirdLife and IUCN.

    Preliminary proposals

    Based on available information, our preliminary proposal for the 2017 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 of 4 August, after which the recommended categorisations will be put forward to IUCN.

    Please note that we will then only post final recommended categorisations on forum discussions where these differ from those in the initial proposal.

    The final 2017 Red List categories will be published on the BirdLife and IUCN websites in early December, following further checking of information relevant to the assessments by both BirdLife and IUCN.

    Recommended categorisation to be put forward to IUCN

    Following further review, the recommended categorisation for this species has been changed.

    White-winged Cotinga is now recommended to be listed as Vulnerable under criteria B2ab(i,ii,iii,iv,v); C2a(i).

    Final 2017 Red List categories will be published on the BirdLife and IUCN websites in early December, following further checking of information relevant to the assessments by both BirdLife and IUCN.
