Population justification: Based on observed estimates of density for this species, the population is thought to number 234 individuals, which approximately equates to 156 mature individuals, hence the species is tentatively placed here in the band 50-249 mature individuals. The scarcity of recent records however, suggests that the species is very rare, so this range may be an overestimate.
Trend justification: The species is suspected to be declining owing to the reduction of its prey base, destruction of habitat and lack of formal protection.
