Population justification: The global population size has not been quantified, but the species is described as common to uncommon (Ferguson-Lees and Christie 2001).

Trend justification: The population is suspected to be declining locally owing to ongoing habitat destruction and increased human disturbance (Ferguson-Lees and Christie 2001).
