Justification of Red List Category
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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to 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.
The global population size has not been quantified, but the species is reported to be uncommon to abundant (Urban et al. 1997).
The population is suspected to be in decline owing to ongoing habitat destruction.
This species has a large range, across the moist lowland forests of West and Central Africa. The subspecies smithii (previously recognised as a separate species) is endemic to the Gulf of Guinea island of Annobón (Equatorial Guinea).
The species is found in moist lowland forests.
The subspecies smithii could be affected by clearance and modification of its habitat for fruit, oil-palm and sugarcane cultivation (BirdLife International 2000).
