Population justification: The global population size has not been quantified, but the species is reported to be uncommon or rare (del Hoyo et al. 2002).
Trend justification: The population is suspected to be in decline owing to loss of suitable nesting and roosting trees and habitat fragmentation (del Hoyo et al. 2002).
