Population justification: Based on mist netting surveys, the global population size has been estimated at c.10,000 mature individuals (Borghesio and Ndang’ang’a 2001).

Trend justification: The population trend is difficult to determine because of uncertainty over the impacts of habitat modification on population sizes.
