Population justification: The global population size has not been quantified, but this species is described as 'uncommon and patchily distributed' (Stotz et al. 1996).
Trend justification: Moderate population declines are suspected owing to the paucity of recent records from many historical sites, as well as the continuing loss of suitable habitats as a result of agricultural conversion.
