Angola Cave-chat (Xenocopsychus ansorgei): downlist to Least Concern?

This discussion was first published as part of the 2013 Red List update, but remains open for comment to enable reassessment in 2014.

BirdLife species factsheet for Angola Cave-chat

Angola Cave-chat Xenocopsychus ansorgei has a localised distribution on the escarpment of western Angola, where it is confined to four areas: eastern Namibe and Huila, N’Dalatando in Cuanza Norte, Mt Soque in Huambo and the Gabela area in Cuanza Sul (Dean 2000). The population size of this species has not been quantified, but it is described as locally common.

It is currently listed as Near Threatened under criterion B1ab(i,ii,iii) because it was thought to have a moderately small range. However, mapping of this species’s range shows that it is larger than previously, with an Extent of Occurrence (EOO) of 37,500km2. Also, its habitat is apparently not under immediate threat, and the population is thus suspected to be stable. As a result, this species should warrant downlisting to Least Concern, on the basis that its EOO does not approach 20,000km2 and it is not in continuing decline.

Further information is required on population size, trends and distribution of this species. Additional comments on the proposed downlisting are also welcome.

    A new location for the species was found in May 2012 when three pairs were seen in the Zebra Mountains of northern Namibia, 240 km south of the closest previously-known population in Angola, and birds have now been seen at other nearby sites with suitable scree slopes. See Swanepoel (2013). Rock Star – Angola Cave Chat – new species for Namibia. African BirdLife Jan/Feb 2013, pp.30-32.

    Preliminary proposals

    Based on available information, our preliminary proposal for the 2014 Red List would be to treat Angola Cave-chat Xenocopsychus ansorgei as Least Concern.

    There is now a period for further comments until the final deadline of 31 March, after which recommended categorisations will be put forward to IUCN.

    The final Red List categories will be published on the BirdLife and IUCN websites in mid-2014, 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, there has been no change to our preliminary proposal for the 2014 Red List status of this species.

    The final categorisation will be published later in 2014, following further checking of information relevant to the assessment by BirdLife and IUCN.
