Justification of Red List category
Most of this species's locations within its very small range are under severe pressure from deforestation and forest degradation. These threats are increasing, deforestation is accelerating and much of its remaining habitat is likely to be cleared in the near future. This is likely have led to an ongoing rapid decline in the species's very small and severely fragmented population. The species is therefore listed as Endangered. Further data from its Mozambique range may lead to its downlisting if substantial populations are confirmed in areas of forest which are not under significant immediate threat and the Extent of Occurrence is greater than currently thought.

Population trend: Decreasing

Extent of occurrence (breeding/resident): 4,700 km2

Country endemic: No

Land-mass type - continent
