Population justification: The population is estimated to number 30-106 individuals, roughly equating to 19-105 mature individuals.

Trend justification: The majority of forest on the island of Sangihe has been cleared for cultivation, and remnant patches continue to be degraded, thus the population is suspected to be in decline at an unquantified rate.
