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 is equivalent to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals. |
|
Trend justification: A moderate and on-going population decline is suspected to be occurring, owing to on-going habitat loss and degradation across the species's range. |
