Sibley, C. G.; Monroe, B. L. 1990. Distribution and taxonomy of birds of the world. Yale University Press, New Haven, USA.
Ceyx fallax and C. sangirensis (del Hoyo and Collar 2014) were previously lumped as C. fallax following Sibley and Monroe (1990, 1993).
Distribution and population
Ceyx fallax is restricted to Sulawesi (race fallax) and the neighbouring Sangihe and Talaud islands (race sangirensis), Indonesia (BirdLife International 2001). It is generally uncommon, although possibly more numerous in parts of Sulawesi, e.g. Panua Nature Reserve (Riley et al. 2003). It may be extinct on Sangihe as a result of habitat loss.
This species inhabits drier primary lowland forest (not associated with water) up to 1,000 m, chiefly c.600 m. It is also recorded from tall secondary and selectively logged forest.
Forest destruction within its elevation range has been extensive in recent decades through logging and conversion to agriculture, and its populations must have suffered a commensurate decline.
Conservation Actions Underway
No targeted conservation actions are known for this species.
Conservation Actions Proposed
Conduct repeated surveys throughout the species's range to determine its current status and assess population trends. Conduct ecological studies to identify its precise habitat requirements and response to habitat degradation or fragmentation. Increase the area of suitable habitat that has protected status and safeguard against logging and agricultural encroachment.
