Lutur Island, Tanimbar


In the past treated as a separate species, but more recently considered a race of C. pileatus. Re-split here on basis of differences in male involving complete white hindcrown (2); white flecks on black throat vs white square on black throat (2); much more extensive white on undertail (2); apparently much longer tail, 66.4 mm vs 57.5 in sample of 8 vs 4 males respectively (allow 2); and (assuming that recordings involve homologous territorial songs and that undocumented buruensis is like nominate pileatus, as it is in plumage) long single whistles vs short multiple whistles (2+3=5)#R. Monotypic.


Tanimbar Is (Larat, Yamdena, Selaru), in E Lesser Sundas; old records from Tayandu Is (Kilsuin), in SE Moluccas#R.
