Justification of Red List category
This species has a large range, hence it does not approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). In the absence of threats, the population trend is suspected to be stable, hence the species is not approaching the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been estimated but is unlikely to be very small hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The population size is not estimated, although this species' abundance (eBird 2023), even on islands with very little forest cover, indicates that it is not especially small.

Trend justification
Rates of forest loss in this species' range are minimal, equivalent to <2% in the ten years to 2022 (Global Forest Watch 2023, based on data from Hansen et al. [2013] and methods disclosed therein). Otus mantananensis is also extremely resistant to habitat pressures, occurring (and breeding) in a range of habitats including plantations and coconut groves (Allen 2020, eBird 2023). In the absence of any other threats to this species, it is suspected to be have a stable population.

Otus mantananensis is endemic to the islets off Sabah (e.g. Mantani), Malaysia, and off Palawan (e.g. Rasa, Ursula) in the Philippines, as well as to islands in the Sulu archipelago and central Philippines (BirdLife International 2001).

It is fairly common in coconut groves and other wooded habitats, including those that are highly modified (Allen 2020, eBird 2023). It hunts at the forest edge or in clearings, feeding primarily on insects. Eggs are thought to be laid in March-May in a tree cavity.
