Archived 2014 discussion: Chapin’s Mountain-babbler (Kupeornis chapini): request for information.

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 Chapin’s Mountain-babbler

Chapin’s Mountain-babbler Kupeornis chapini is restricted to the Albertine Rift mountains of the Democratic Republic of Congo, where it is known from the Lendu Plateau, mountains west of Lake Edward, mountains west of Lake Kivu, and the Itombwe Mts. It is currently listed as Near Threatened under criterion B1ab(i,ii,iii,v) owing to its moderately small range, in which it is threatened by deforestation for shifting agriculture.

However, mapping of this species’s range has shown that it is larger than previously thought, with an Extent of Occurrence (EOO) of 43,900km2. Thus, it no longer approaches the thresholds for Vulnerable under the range size criterion and its status requires reassessment.

The global population size has not been quantified, but the species is described as evidently rather rare (del Hoyo et al. 2007), and the population is suspected to be in decline owing to ongoing habitat clearance for shifting agriculture (del Hoyo et al. 2007). Any evidence that the global population of this species is less than 10,000 mature individuals, all subpopulations are ≤1,000 mature individuals and in continuing decline, would make this species eligible for uplisting to at least Vulnerable under the C criterion. If the species approaches but does not exceed these thresholds for classification as Vulnerable, it should remain classified as Near Threatened (but listed under the C criterion).

Information is required on this species’s likely global population size, trends and size of the largest subpopulation.

    Preliminary proposals

    Based on available information, our preliminary proposal for the 2014 Red List would be to treat Chapin’s Mountain-babbler Kupeornis chapini as Near Threatened, approaching the threshold for Vulnerable under criterion A2c+3c+4c.

    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.
