Justification:
This species is assessed as Vulnerable because of ongoing population decline of at least 30%, inferred from the rapid rate and extent of deforestation on Sulawesi, especially in the lowland areas, as well as levels of direct exploitation from small-scale hunting.

History:

1996

–

Lower Risk/least concern (Baillie and Groombridge 1996)
