Local name; Merbah Berjanggut meaning bearded bulbul, quite large about 23cm in length.
Merbah Beringin was named by the Department of Wildlife and National Park (Perhilitan)
UPDATE: 21/3/2011 @12.17pm - Rainfield61 and Thomas mention about the bird sound.
So, here I got it from Xeno-canto. (call from 2 birds). Maybe this bird mimics the punk music/song.
