Frog Voices of Borneo

Links to the sound files will be added soon.

T.U. Grafe & J.M. Dehling

Frogs are more often heard than seen. Here we make available high quality wave (.wav) recordings of the advertisement calls of the most commonly encountered Bornean frogs. This will aid researchers and practitioners in identifying frogs of interest. Most frog calls were recorded in Brunei or in the Malaysian states of Sabah or Sarawak. The species have been sorted into three categories to allow easier identification depending on where a listener is: (1) urban, heavily degraded habitat, (2) forests at low elevations ( 900 m ASL).  Advertisement calls of 67 species are made available as well as four soundscape recordings in which the full complexity of frog chorusing behaviour can be heard. UTNP = Ulu Temburong National Park, Brunei, BBBR = Bukit Baka Bukit Raya, West Kalimantan.
