Philby's Partridge Alectoris philbyi

Handsome partridge of the southwest Arabian mountains. Mostly pale gray and tan, with chestnut-and-white slashes along the sides, and a black face mask. In flight, shows dark wingtips and chestnut sides to the tail. Found in dry, rocky habitat at middle and high elevations, with a preference for bush areas. The common vocalization, given mainly early and late in the day, is an emphatic series of “chuk-chek-chuk” calls. Also gives clucking calls, especially when flushed. Similar to Arabian Partridge, but distinguished by the black face mask, and when in flight, by the chestnut in the tail.
