Bulbuls(Pycnonotidae) are a strictly Old World family of birds usually characterized by long hairlike feathers on their nape, evident in this photo. This is the race Pycnonotus goiavier jambu which ranges from southern Burma to southern Indochina. It is darker and more dingy on the underparts than Pycnonotus goiavier personatus (analis is a synonym) which replaces it on the Malay Peninsula to the south.
