This species
is endemic to Sulawesi and offshore islands of Lembeh, Togian Islands, Muna and Butung,
Indonesia. It is described as 'common' in at least parts of its range (del Hoyo
et al. 2001). However, a recent analysis has suggested that this species may be declining at a rate approaching 40% over three generations based on recent and ongoing rates of habitat loss on Sulawesi (D. Holmes
in litt. 1999, Kinnaird and O'Brien 2007).
