"In this Sunday, Dec. 2, 2012 photo, a park official feeds a two-and-half month old male orphan one-horned rhinoceros calf rescued during recent floods walks at a rehabilitation center inside the Kaziranga National Park, a wildlife reserve that provides refuge to more than 2,200 endangered Indian one-horned rhinoceros, in the northeastern Indian state of Assam. Even in this well protected reserve, where rangers follow shoot-to-kill orders, poachers are laying siege to ""Fortress Kaziranga,"" attempting to sheer off the animals' horns to supply a surge in demand for purported medicine in China that's pricier than gold. A number of guards have been killed along with 108 poachers since 1985 while 507 rhino have perished by gunfire, electrocution or spiked pits set by the poachers, according to the park.
