Population justification: Historical records indicate that this species was once fairly common, at least locally on Wetar and in West Timor, even near settlements. A paucity of records, despite extensive searching, suggested that a marked decline then occurred in West Timor (e.g. Noske and Saleh 1996). However, recent survey work in Timor-Leste revealed it to be frequent in a wide range of habitats, and surveys of Wetar in 2008 showed it to be "widespread and fairly common" at all tropical forest sites (Trainor et al. 2004, 2009). A recent visit to the Oecusse enclave in Timor-Leste however found lower records in this region (C. Trainor in litt. 2020). The population on Rote is additionally suggested to be very small, estimated at c. 100-200 individuals (C. Trainor in litt. 2020). Taking this into account therefore, it is suspected that the population may still number less than 10,000 mature individuals, placed here in the band of 2,500-9,999.

Trend justification: Tree cover loss within the species' range equates to 6-7% over three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). However, habitat loss may not be a severe threat as the species is highly mobile and presumably able to access necessary fruit resources over a large area (C. Trainor in litt. 2005). Recent survey work in Timor-Leste has also revealed it to be frequent in a wide range of habitats, and surveys of Wetar in 2008 showed it to be "widespread and fairly common" at all tropical forest sites (Trainor et al. 2004, 2009). Extensive forest also remains on Wetar (Baptista et al. 2020, Global Forest Watch 2022). The species is however intensely hunted on much of Timor (C. Trainor in litt. 2005, Baptista et al. 2020), likely adding an extra 5% loss, and driving declines beyond the rate of forest loss alone. The overall population is therefore suspected of declining at a maximum rate of 11-12%, and as such, declines are placed here in the band of of 5-15% over three generations.
