The hoolock gibbons are now ranked one of four genera of the family Hylobatidae (Roos and Geissmann 2001; Brandon-Jones et al. 2004). They occur in closed canopy forest areas between the Salween River in the east and the Brahmaputra River in the west (Groves 1967; Marshall and Sugardjito 1986), including eastern India and Bangladesh, most of Myanmar, and a small part of Yunnan, China, that occurs west of the Salween River. Groves (1967) considered the hoolock to have two subspecies, Hylobates hoolock hoolock, the western Hoolock gibbon, and H. h. leuconedys, the eastern hoolock gibbon, separated by the Chindwin River system. This separation was supported by pelage differences in specimens in the American Museum of Natural History and the British Museum. More recently, Mootnick and Groves (2005) replaced the previous generic name proposed for the genus, Bunopithecus (Prouty et al. 1983), with Hoolock, and proposed elevating the two subspecies to species level.

We are grateful to officials of WCS Myanmar, especially Dr. Madhu Rao, U Than Myint, and U Saw Htun, for arranging the activities under this project and for their participation, and to Mrs. Bibiana for her kind administrative support. We thank U Myint Aung, Warden of Chathin Wildlife Sanctuary, for his enthusiastic help and participation in the workshop and first census activities. U Yee Htut, Warden of Mahamyaing Wildlife Sanctuary, provided indispensable help and support during the census activities and made my stay comfortable and productive. We are grateful to Mr. Kumar and the staff of the Myanmar Timber Enterprise facilities at Thetkegyin, for their excellent support and meals throughout the workshop. Finally, we are extremely pleased to have the support of U Khin Mg Zaw, Director of the Nature and Wildlife Conservation Division, who has insured the success of this project.
