Population justification: The species's population is estimated to number 2,500-10,000 individuals (F. Hawkins in litt. 2002 to Wetlands International 2002). This roughly equates to 1,600-6,700 mature individuals.
Trend justification: This species's population is inferred to be declining due to ongoing habitat loss owing to transformation of its aquatic and wet forest habitats by agricultural and logging activities (Kull 2012). The likely rate of future decline is suspected to fall in the 30-49% band.
