Three black-necked cranes (Grus nigricollis) are seen in Burang County of Ali Prefecture in southwest China's Tibet Autonomous Region, Oct 23, 2014. The wildlife population in Ali Prefecture has grown as China makes increasing efforts to curb illegal hunting in the country's natural reserves. Ali Prefecture, which is among the most remote areas in Tibet Autonomous Region, is home to 19 rare and endangered species including the Tibetan antelope and the snow leopard. [Photo/Xinhua]
