A mahout walks past with an elephant used for tourist rides as a World Wide Fund for Nature (WWF) official carries an unmanned aircraft or drone before flying them at the Kaziranga National Park at Kaziranga in Assam state, India, Monday, April 8, 2013. Wildlife authorities used drones on Monday for aerial surveillance of the sprawling natural game park in northeastern India to protect the one-horned rhinoceros from armed poachers. The drones will be flown at regular intervals to prevent rampant poaching in the park located in the remote Indian state of Assam. The drones are equipped with cameras and will be monitored by security guards, who find it difficult to guard the whole 480-square kilometer (185-square mile) reserve. (AP Photo/Anupam Nath)
