Justification of Red List category
Although this species may have a restricted range, it is not believed to 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 may be moderately small to large, 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.
Trend justification
The population is suspected to be stable as its habitat in the Congo and Gabon is likely to be secure, since it is unsuitable for agriculture (Collar and Stuart 1985, Dowsett and Dowsett-Lemaire 1989, F. Dowsett-Lemaire in litt. 1997).
This species occurs in the Bailundu Highlands of western Angola, on the Batéké Plateau in the Congo and in eastern Gabon around Lekoni.
This species inhabits wooded grassland dominated by Hymenocardia acida 6-8 m high. It is mainly found between 500-700 m on the Batéké Plateau, but above 1,500 m in the Bailundu Highlands.
