Archived 2016 topics: Liberian Greenbul, Phyllastrephus leucolepis, is to be listed as Data Deficient.

Liberian Greenbul, Phyllastrephus leucolepis, has been recorded from two forest patches in south-east Liberia (Gatter 1985), and was previously listed as Critically Endangered under criterion B1ab(i,ii,iii,v). Surveys in 2010 and 2013 both failed to find the species (Molubah and Garbo 2010; Phalan et al. 2013), and it is only known from the type specimen and further sightings from the collector of that specimen in the area around the type locality; with the most recent sighting in 1985 (see Fishpool et al. 2016). Its status remains unclear, in particular its relationship to Icterine Greenbul, P. icterinus, (which it very closely resembles) (Fishpool et al. 2016) and so, given the current uncertainty over its status and the lack of recent information regarding this species, it will be re-assessed as Data Deficient.

  1. James Westrip (BirdLife) says:

    Based on available information, our preliminary proposal for the 2016 Red List would be to adopt the proposed classifications outlined in the initial forum discussion.

    Please note that we will then only post final recommended categorisations on forum discussions where these differ from those in the initial proposal.

    The final 2016 Red List categories will be published on the BirdLife and IUCN websites in early December, following further checking of information relevant to the assessments by both BirdLife and IUCN.
