Population justification: This species has only rarely been recorded (with no records since 2009; Allen ). It may therefore be genuinely very rare, or it could be that the region and habitat it occupies remains to be extensively searched. Consequently, even qualitative estimations of its abundance are considered unreliable.
Trend justification: The population trend is of this species is wholly unknown due to there being nothing precisely known of its distribution, habitat requirements or biology. It may however be in decline because of human predation (BirdLife International 2001).
