Population justification: This species is described as uncommon in primary and secondary forest patches (Eaton et al. 2021). Fieldwork in 1989 and 1992 yielded density estimates of 6.9 (±1.2) birds per km² (Jones et al. 1995). Given 1,080 km² of closed-canopy forest on Sumba, this was extrapolated and corrected upwards to a global population estimate of 9,100 birds (Jones et al. 1995), roughly equivalent to c.6,000 mature individuals. Given nearly 30 years has passed since the creation of this estimate, it is in need of confirmation; however assuming the rate of forest loss since this time is axiomatic with population declines, it may have declined by c.6% since. Consequently, it is now estimated to number 5,600-6,000 mature individuals.

Trend justification: Though it may be partially tolerant of degradation, as a forest-dependent species it is suspected to be in decline owing to ongoing habitat loss within its range. Forest cover extent in this species' range reduced by c. 6% overall in the three generations to 2022 (Global Forest Watch 2023, based on data from Hansen et al. [2013] and methods disclosed therein), and based on losses in 2018-2022 this has accelerated slightly to an equivalent rate of c. 7% in three generations. Hunting is a potential additional threat, though this remains unconfirmed. Tentatively, declines are placed in the range 5-10% in three generations and this is suspected to continue.
