A yellow-cheeked crested gibbon sits in a cage at Cambodia's Phnom Tamau Zoo in Takeo province, about 45 kilometers (28 miles) south of Phnom Penh, Cambodia, Friday, Aug. 29, 2008. The New-York-based Wildlife Conservation Society announced its findings in a statement Friday. The group says its researchers, working with Cambodian wildlife officials, have counted 42,000 black-shanked douc langurs along with 2,500 yellow-cheeked crested gibbons in the Seima Biodiversity Conservation area in a remote northeastern corner of the country.
