Population justification: The population is estimated to number 2,500-9,999 mature individuals, based on an assessment of recent records and surveys by BirdLife International (2001). This equates to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.
Trend justification: A moderate population decline is suspected to be on-going, owing to the moderately rapid loss and degradation of habitats across the range.
