The Sulu jungle flycatcher is a species of passerine bird in the Old World flycatcher family Muscicapidae. It is endemic to the Sulu Archipelago. Its natural habitat is tropical moist montane forests. While it has yet to be assessed by the International Union for Conservation of Nature, this species is likely threatened by habitat loss.
Region
Sulu Archipelago
Typical Environment
Occurs in remnant primary and mature secondary tropical moist forest within the Sulu Islands, favoring interior, undisturbed tracts. It uses dense understory with thickets, vines, and rattan, often near streams, gullies, and steep slopes. The species typically keeps to low to mid understory perches and avoids open edges when possible. It may persist in partially degraded forest if a shaded, complex understory remains, but it is sensitive to extensive habitat loss.

The Sulu jungle flycatcher is a little-known member of the Old World flycatcher family Muscicapidae, restricted to the Sulu Archipelago of the southern Philippines. It keeps to dense, shaded forest where it is more often heard than seen, darting out from low perches to snatch insects. Its taxonomy has been revised alongside other jungle flycatchers in recent years, but it remains poorly studied. Ongoing deforestation in its tiny range is considered the main threat.
Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats with quick sallying flights from low perches
Social Behavior
Usually encountered alone or in pairs during the breeding season. Nests are presumed to be cup-shaped and placed low in dense vegetation, as in related jungle flycatchers. It may join mixed-species flocks occasionally while foraging but tends to remain unobtrusive within the understory.
Migratory Pattern
Resident
Song Description
A series of thin, high-pitched whistles and soft trills delivered from concealed perches. Calls include sharp, dry ticks or chips used for contact and alarm. Vocalizations carry poorly in dense foliage, adding to the species’ elusiveness.
Plumage
Subtly patterned, with dull brown to olive-brown upperparts and paler buffy underparts; often shows a faint pale eyebrow and a slightly warmer, rufous-tinged tail. Feathers are soft-textured, aiding camouflage in shaded understory. The overall appearance is plain, relying on posture and behavior for recognition.
Diet
Feeds primarily on small insects and other arthropods, including beetles, ants, flies, and spiders. It employs sit-and-wait tactics, sallying out to snatch prey from the air or gleaning from leaves and twigs. Foraging is typically low, within a few meters of the ground, and often along shaded trails or stream margins.
Preferred Environment
Dense, shaded understory inside intact or mature secondary forest, especially near watercourses and gullies. Frequently uses low perches with good cover from which to launch short sallies. Avoids open areas and heavily disturbed forest.
