| There are exotic animals from throughout the world, such as aoudads and yaks. |
| It was only after the Mongols tamed horses, yaks and camels that they took to a nomadic herding lifestyle. |
| Horses, and at high altitudes, yaks, are used instead of porters to carry loads. |
| Now black yaks and white sheep graze peacefully on dry grassland, tended by Tibetan herdsmen clad in bright orange. |
| Then we freewheeled down countless switchbacks to Sangdu, nestled in the corner of a wide earthy valley dotted with ponies, pigs and yaks. |
| The evacuation began with moving out the yaks, continued with tranquilizing the eight large cats and finished with caging the birds. |
