BirdLife species factsheet for Grey-headed Greenbul Grey-headed Greenbul Phyllastrephus poliocephalus is restricted to the montane forests of eastern Nigeria and western Cameroon, where it was discovered on the southern slopes of Mt Manenguba in the 1990s (Dowsett-Lemaire and Dowsett 1999), but is not found in the Bamenda Highlands (Stuart 1986) (earlier records from Mt Oku are now known to be in error [Dowsett-Lemaire and Dowsett 1998]). It is currently listed as Near Threatened under B1ab(i,ii,iii) because it was thought to have a moderately small range in which it is threatened by habitat loss and degradation. However, mapping of this species’s range suggests that it is larger than previously thought, with an estimated Extent of Occurrence of 31,400km2. As a result, it no longer qualifies as Near Threatened under the range size criterion. The global population size has not been quantified, but the species is described as common (del Hoyo et al. 2005) to very common in suitable habitat (P. Hall in litt. 1999, Dowsett-Lemaire and Dowsett 2000). If this information is confirmed, this species would warrant downlisting to Least Concern on the basis that it does not approach the thresholds for Vulnerable under any of the IUCN Red List criteria. Information is required on the population size and trends of this species. Additional comments on the proposed downlisting are welcome. References: del Hoyo, J., Elliott, A. and Christie, D.
