The only known colony in Southeast Asia of slender-billed vultures (Gyps tenuirostrishas) – shown above – have been discovered in Cambodia, along with other endangered bird species. The vulture colony was discovered in January 2007, in the rainforests east of the Mekong River in Cambodia’s Stung Treng Province, according to Michael Casey’s Associated Press Bangkok-based dispatch for February 7, 2007.

The slender-billed vultures were believed extinct throughout Southeast Asia, including Thailand and Cambodia, and only having been found in northern India recently. Some call it the world’s rarest vulture.

The team also spotted a red-headed vulture, giant ibis and an endangered primate called a silvered langur, or leaf monkey.
