A glossy-black starling with a big permanently raised crest that gives it a unique, broad-headed profile. Also note prominent whitish markings on sides of neck and breast, which appear like one large patch. Juvenile shorter-crested, with a brown chin and a bicolored bill. Frequents the canopy of lowland and hill forest in small groups or pairs, preferring pristine areas, but straying into edges and degraded patches too. Complex song involves whirring “weee-ow-weee-ow” mixed with “chur” and “chip” notes. Also gives a single, strident metallic “chip” call.
