Archived 2014 discussion: Bedford’s Paradise-flycatcher (Terpsiphone bedfordi): 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 Bedford’s Paradise-flycatcher

Bedford’s Paradise-flycatcher Terpsiphone bedfordi is restricted to the Democratic Republic of Congo where it occurs as two disjunct populations, one in north-east Ituri and the other west of Itombwe (Urban et al. 1997). The global population size has not been quantified, but the species is described as rare to frequent within its range (del Hoyo et al. 2006). It is currently listed as Near Threatened under criterion B1ab(i,ii,iii,iv,v) because it was thought likely to have a moderately small range, which may be in decline owing to habitat loss and degradation.

However, recent remapping of this species’s range has shown that it is larger than previously thought, with an Extent of Occurrence (EOO) of 42,600km2. If this information is confirmed, this species would no longer qualify as Near Threatened, on the basis that its EOO does not approach 20,000km2, and should warrant downlisting to Least Concern, providing its population size is not thought to approach 10,000 mature individuals, with all individuals in one subpopulation or all subpopulations approaching 1,000 mature individuals; and it is not suspected to be declining at a rate of ≥25% in three generations (17 years).

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

    Preliminary proposals

    Based on available information, our preliminary proposal for the 2014 Red List would be to treat Bedford’s Paradise-flycatcher Terpsiphone bedfordi as Near Threatened, approaching the threshold for Vulnerable under criteria 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.
