Siffleur moine Pachycephala monacha

A medium-sized bird of lower montane disturbed areas. Black upperparts, head and chest with white belly. Gray replaces black in the female. Has been known to hybridize with White-bellied Whistler. Similar to several species, but Black-headed Whistler is stockier than Satin Flycatcher, has a shorter tail and lacks the white brow of Willie Wagtail and is not found in forest interior like Hooded Monarch. A typical whistler song, with a variety of whistles and warbles, often ending in a sharp “wik!”.
