In order to save three critically endangered species – the white-rumped, slender-billed and red-headed vultures – the Wildlife Conservation Society (www.wcs.org) set up a ‘vulture restaurant’ in the village of Dongphlet, northeast of Chhep on the edge of the Preah Vihear Protected Forest. A cow carcass is put out in a field, and visitors waiting in a nearby bird hide watch as these incredibly rare vultures move in to devour the carrion.
Visits are offered by Siem Reap–based Sam Veasna Center.
Trips here involve an overnight at a WCS forest safari camp. Access to the site is year-round, but try to give SVC at least a week's notice to assure your spot.
