Archived 2010-2011 topics: Elusive Antpitta (Grallaria eludens): downlist to Least Concern?

Elusive Antpitta Grallaria eludens occurs in south-east Peru in Ucayali (Balta and on the Cordillera Divisor), and probably Madre de Dios (Manu National Park and Cerro Pantiacolla), and has recently been discovered on the upper rio Juruá, Brazil. It is listed as Near Threatened on the IUCN Red List because it was thought to have a restricted range that approaches the threshold for listing as Vulnerable (<20,000 km2) combined with severely fragmented habitat or occurrence at approximately ten or fewer locations and a continuing decline in its habitat, population size or number of locations/sub-populations.

However, this species has been mapped by Natureserve/BirdLife International as having an estimated Extent of Occurrence (EOO) of 384,000 km2, hence it does not appear to approach the IUCN thresholds and appears to warrant downlisting to Least Concern. However, if the species has experienced declines over the past three generations (14 years, BirdLife International unpubl. data) approaching 30% it may warrant listing as Near Threatened under the A criterion (population declines). Given its relatively large range size it seems unlikely that this species will have a population approaching 10,000 mature individuals so it would not qualify as threatened or Near Threatened on population size under the C criterion.

Comments on the population trends of this species and its proposed downlisting are welcomed.

  1. Given a relatively large range in Amazonian forest that in Peru, at least, is under fairly limited developmental pressure. I would favor changing its status to Least Concern. The only counter argument would be that the species is routinely considered rare. Could be that data deficient would be another option.
