布路姬鶲

The cinnamon-chested flycatcher (Ficedula buruensis) is a small Old World flycatcher in the family Muscicapidae, endemic to Buru Island (Pulau Buru) in the Maluku province of eastern Indonesia. It inhabits the montane and hill forest of Buru, one of the larger islands of the Maluku archipelago, at elevations from approximately 600 to 2,100 meters. The species is characterized by the male's dark blackish-blue upperparts and vivid cinnamon-rufous underparts. Like other Ficedula flycatchers, it is an active, aerial insectivore, hawking insects from low to mid-height perches in forest understorey and edge. The cinnamon-chested flycatcher is classified as Least Concern by the IUCN, with populations considered stable within Buru's montane forest. Buru Island is considered a center of avian endemism, harboring multiple restricted-range species found nowhere else. The island's forests face pressure from logging and shifting cultivation, though montane areas remain relatively intact. The species is absent from Europe entirely; Norwegian database records are geographic data errors. Conservation of montane forest on Buru Island is important for this and other Buru endemics. The genus Ficedula includes numerous island endemic flycatchers across Southeast Asia and the Pacific, many with small restricted ranges.
