. . . . . . "Pachycephala is a genus of birds native to Oceania and Southeast Asia. They are commonly known as typical whistlers. Older guidebooks may refer to them as thickheads, a literal translation of the generic name, which is derived from the Ancient Greek terms pachys \"thick\" + kephale \"head\". This lineage originated in Australo-Papua and later colonized theIndonesian and Philippine archipelagos to the west and the Pacific archipelagos to the east."@en . .
