Sumba Brown Flycatcher Muscicapa segregata

Justification
This species is associated with forest habitat, which is being cleared within its small range. However, this is not yet severely fragmented, and the species not restricted to few locations. For these reasons, the species is classified as Near Threatened.

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
Muscicapa segregata (split from Asian Brown Flycatcher M. dauurica) is restricted to Sumba, Indonesia. Previously thought to be rather scarce and local, a more recent assessment considered it uncommon and sparse, perhaps rare, although quiet and unobtrusive. The most recent observations confirm that it is widespread in remaining patches of both primary and secondary forest, albeit declining with steady habitat clearance.

Population justification
The population size is unknown, but the species is described as uncommon or rare (del Hoyo et al. 2006).

Trend justification
The population is suspected to be in decline owing to ongoing habitat destruction.

Ecology
It occupies lowland primary forest, including forest edges bordering cultivation, and secondary forest from sea-level to 500 m. It forages on insects in the understoreys of forest and pursues insects in flight. Usually solitary, spending long periods sat unobtrusively on a perch.

Threats
Ongoing habitat clearance through agricultural expansion and subsistence logging represent the main threats.

Conservation Actions Underway
None are known. Conservation Actions Proposed
Protect areas of lowland forest within the species's range. Enforce restrictions on agricultural encroachment and logging within such protected areas. Generate density estimates to inform a revised population estimate for the species. Estimate population trends by calculating rates of forest loss within its range using satellite imagery and remote sensing techniques.
