Habitat and Ecology:	It is confined to primary and secondary lowland rainforest, where it is dependent upon very large tree holes (an uncommon microhabitat) in which it breeds. It has been found in wet evergreen and moist semi-deciduous forest but is not found in degraded habitats.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	The major threat to this species is ongoing forest loss in south-western Côte d’Ivoire, due to agricultural development, timber extraction and human settlement.
