In parts of China, Kazakhstan, Russia and Mongolia, men have been using birds to hunt for meat and fur for centuries. China's ethnic Kazakh minority is now doing all it can to preserve that ancient art.
Getty Images photographer Kevin Frayer has documented one such effort, an eagle-hunting festival which was organized by the local hunting community in Qinghe County in China's northwestern Xinjiang province last month.
The hunters, who ride on horseback with an eagle on their arm, are known locally as the "Lords of the Birds," the BBC reported.
Take a look at Kevin Frayer's stunning photos of the eagle hunters below.
