Notably less vocal than other Asian broadbills, but rather poorly studied.


Vocal Array

Often silent, with calls quieter than those of most eurylaimids.


The most frequently heard call in Laos was an accelerating series of parnk notes, likened to the sound made by the wingbeats of Wreathed Hornbill (Rhyticeros undulatus) (1). Other calls include grating notes as if from a cicada (Cicadidae), which is thought to be given in advertisement, as well as churring calls, melodious whistles, a monotonous repeated tyook, and a rasping wiark (47, 2). Also utters an ascending trill like that of Black-and-yellow Broadbill (Eurylaimus ochromalus) but shorter, much slower, softer, and quieter (2). In alarm, a rapid series of pip notes; in Sarawak, a hoarse, grumbling ka-ka-kraaar-kraaar that falls in pitch (47); in Brunei, a hoarse twanging cow, and a snarl likened to that of cornered puma (Felis concolor).
