The expansive forests and untouched wetlands of this small country harbor some of the rarest species of birds and mammals in Asia. In recent years a number of hugely exciting discoveries have been made, including a healthy population of the near-mythical Giant Ibis, a new species—the Mekong Wagtail, and a breeding population of the rapidly declining eastern race of Sarus Crane. In addition, a healthy breeding population of White-shouldered Ibis has been found in the northern province of Preah Vihear along with White-winged Duck, Green Peafowl, and White-rumped Falcon. On the wetlands around the amazing Tonle Sap Lake, enormous breeding colonies of waterbirds represent one of the finest birding spectacles in Asia. Healthy populations of Greater Adjutant, the still relatively common Lesser Adjutant, Milky Stork, and Spot-billed Pelican can also be observed nesting at Preak Toal. The most extensive grasslands remaining in Southeast Asia are where we seek more scarce beauties, in particular Bengal Florican and Manchurian Reed-Warbler. A number of other species, uncommon in neighboring countries, can be found here in abundance: Rufous-winged Buzzard, Black-headed Woodpecker, and Comb Duck among them.
