Population justification: The global population size has not been quantified, but the species is reported to be widespread and locally common in suitable habitat (del Hoyo et al. 2001). The population is suspected to be in decline locally owing to ongoing habitat destruction and competition with N. nasutus (del Hoyo et al. 2001).
