Assessment Information
Red List Category & Criteria:
Least Concern ver 3.1
Year Published:
2004
Date Assessed:
April 30, 2004
Annotations:
Needs Updating
Justification:
Listed as Least Concern in view of its wide distribution, its presumed large population, and because it is
unlikely to be declining fast enough to qualify for listing in a more threatened category.
Geographic Range
Range Description:
This species ranges from southeastern most Nigeria, southwestern Cameroon, mainland Equatorial
Guinea, western Gabon and southwestern Congo to extreme western Democratic Republic of Congo. It
presumably occurs in the Cabinda Enclave of Angola. Records from the island of Bioko (Equatorial
Guinea) and from Fort Crampel in central Central African Republic are not confirmed (this last record is
found significantly outside the known range of the species).
Country Occurrence:
Native: Cameroon; Congo; Congo, The Democratic Republic of the; Equatorial Guinea; Gabon; Nigeria

Population
It is a reasonably common species.
Current Population Trend: Decreasing
Habitat and Ecology (see Appendix for additional information)
It is an arboreal species of humid lowland rainforest, occurring in secondary forest, but not normally out
degraded vegetation outside forest. It breeds in streams, the eggs presumably are laid in nests on land
close to the water.
Systems: Terrestrial, Freshwater
Threats (see Appendix for additional information)
It is affected by habitat loss as a result of expanding human settlements and agriculture, and the
harvesting of wood.
Conservation Actions (see Appendix for additional information)
It occurs in several protected areas, including Korup National Park in Cameroon and Monte Alen
National Park in Equatorial Guinea.
