Population justification: The population is estimated to number 2,500-9,999 mature individuals, based on a detailed analysis in BirdLife International (2001), who concluded that its total population numbers no more than a few thousand individuals. This estimate equates 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, owing to habitat degradation across the species's range. |
