Population justification: The global population is estimated to number 670,000 mature individuals (Partners in Flight 2019).

Trend justification: Anthropogenic processes are potentially affecting this species both positively and negatively, but given its tolerance to disturbance (del Hoyo et al. 2004) the global population is tentatively assessed as being stable (see also Partners in Flight 2019).
