Mt Kinabalu, northern Borneo

.

Until recently considered conspecific with C. thalassina, but it has different, purer whistles leading to complex phrases given by either one or (asynchronously) two birds (at least 2); appears to lack thalassina’s long series of fast repeated identical notes (at least 1)#R; and, on basis of published evidence#R, it differs further in its longer tail (effect size 3.97; score 2); shorter wing and tarsus (effect size −2.15) and shallower bill (−3.38) (score 2); whitish vs red irides (3); and tail with dark subterminal bars and white tips vs no such pattern (3). Monotypic.

Distribution:

N Borneo from Mt Kinabalu S to Mt Murud, the Usan Apau Plateau, Mt Dulit and Menyapa Mts#R.
