Sulawesi Blue Flycatcher Cyornis omissus Scientific name definitions

The Sulawesi Blue Flycatcher is a somewhat common but poorly known forest flycatcher of Sulawesi and smaller neighboring islands. This species inhabits dense understory of forest and second growth, primarily in hill and lower montane forest on Sulawesi and lower elevations on smaller islands. Many aspects of life history, including behavior and breeding, remain essentially undescribed. It was long considered conspecific with the widespread Mangrove Blue Flycatcher (Cyornis rufigastra), but differences in habitat, voice, plumage, and genetics separate them. Sulawesi Blue Flycatcher is sometimes split further: the subspecies on Tanahjampea sometimes considered a separate species, while the Kalao Blue Flycatcher (Cyornis kalaoensis) was formerly considered a subspecies but is currently split as a separate species.
