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.
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.
