Mantanani Scops-owl Otus mantananensis

Justification
This species is listed as Near Threatened because there are some indications that its very small range is occupied by a moderately small, fragmented population which is undergoing a continuing decline owing to forest loss and degradation. However, little is currently known about the species's population size and structure, and the impact of threats, and its population is not regarded as severely fragmented or restricted to a few locations.

Taxonomic source(s)
Sibley, C. G.; Monroe, B. L. 1990. Distribution and taxonomy of birds of the world. Yale University Press, New Haven, USA.

Distribution and population
Otus mantanensis 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 apparently common in suitable habitat. The total range size is very small.

Population justification
This species is poorly known, but is common on at least some of the islands where it occurs. Overally the population is assumed to be moderately small. It is placed in the band 10,000-19,999 individuals, equating to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.

Trend justification
The population is suspected to be in decline owing to on-going habitat destruction.

Ecology
It is fairly common in coconut groves and other wooded habitats, although its total area of occupancy is small. 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.

Threats
It is confined to increasingly disturbed and degraded habitats within a small range.

Conservation Actions Underway
None are known. Conservation Actions Proposed
Survey known islands and ascertain its tolerance of habitat degradation. Assess the rate of habitat loss and area of suitable habitat remaining. Protect key sites within the range for this, and other Threatened and Near Threatened species.
