The Ngalops who have settled mostly in the six regions of western Bhutan are of Tibetan origin. They speak Ngalopkha, a polished version of Dzongkha, the national language of Bhutan. Agriculture is their main livelihood. They cultivate cereals such as rice, wheat, barley and maize along with a variety of other crops. In the regions of Thimphu and Paro apples are also cultivated as a cash crop. They are known for Lozeys, or ornamental speech and for Zheys, dances that are unique to the Ngalops.
