Introduction

The yellow-cheeked crested gibbon (Nomascus gabriellae) occurs east of the Mekong River in southern Vietnam, northeastern Cambodia, and possibly southernmost Lao PDR (2000, Nomad RSI unpubl. data). The northern distributional limit is unclear as it either borders or intergrades with the southern white-cheeked crested gibbon, N. siki (Duckworth et al. 1995, 1999; Geissmann et al. 2000; Konrad 2004). N. gabriellae is currently listed as Endangered in the IUCN Red List of Threatened Species (IUCN 2008).

Little behavioral or ecological work was conducted on the species until recent years; however, a picture of the species is beginning to emerge with current studies, particularly in the SBCA (Rawson 2004) and Ratanakiri province, Cambodia (Traeholt et al. 2006), and Cat Tien National Park (NP) in Vietnam (M. Kenyon pers. comm.). It appears that N. gabriellae generally prefers undisturbed evergreen forest with a reasonably high canopy (Nguyen Xuan Dang and Osborn 2004; Traeholt...
