LC
Icterine Greenbul Phyllastrephus icterinus

Justification
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Taxonomic note
Phyllastrephus lorenzi (Sibley and Monroe 1990, 1993) is considered a synonym of P. icterinus following Fishpool (2006).

Distribution and population
Subspecies P. i. lorenzi (formerly considered a separate species) is apparently scarce, and is restricted to the eastern lowlands of Democratic Republic of Congo (DRC) and also at Ntandi in Semliki Forest in Uganda (Keith et al. 1992). In the DRC, there is a somewhat isolated record from Bambesa as well as populations in the Semliki/Ituri Forests and from the lowland parts of the Itombwe Mountains (Stattersfield et al. 1998).

Population justification
The global population size has not been quantified, but the species is described as generally common to abundant (del Hoyo et al. 2005).

Trend justification
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Ecology
It is a species of lowland and transitional forest at altitudes of 700-1,800 m (Stattersfield et al. 1998), where it occurs in mid-levels in small groups and in mixed-species flocks (Keith et al. 1992).

Threats
Forest habitats occupied by the range-restricted subspecies P. i. lorenzi are threatened by clearance for shifting cultivation and degradation through the removal of understorey tree species to create cacao plantations (Howard 1991).
