Birds are few on these stony wastes, larks, wheatears and snow-finches being the commonest. Elwes' shore-lark was found feeding young birds at the beginning of June, when the ground was not yet free from snow, and the song of the Tibetan skylark, remarkably like that of our own skylark, was heard over every patch of native cultivation.

A small spiny lizard (Phrynocephalus theobaldi) is common on the plains and on the lower hills up to 17,000 feet; it lives in shallow burrows on the sand and under stones.

Rising out of the plain North of the Himalayas are ranges of rounded limestone hills, 18,000 to 19,000 feet high, running roughly East and West. The hills between Phari and Khamba Dzong are the home of the big sheep (Ovis hodgsoni), which are occasionally seen in small companies. There are many ranges to the West of Khamba Dzong, apparently well suited to this animal, but it was never seen. On the slopes of these hills are found partridges (Perdix hodgsoniæ), and in the ravines are seen Alpine choughs, rock-doves (Columba rupestris) and crag-martins. Once or twice at night we heard the shriek of the great eagle-owl, but the bird was not seen.

At rare intervals on these plains one meets with small rivers, tributaries of the Arun River; along their banks is usually more grass than elsewhere, and here the wandering Tibetan herdsmen bring their yaks to graze. The wild yak is not found anywhere in this region. It might be supposed that so hairy an animal as the yak would become dirty and unkempt. Actually they are among the cleanest of creatures, and they may often be seen scraping holes in soft banks where they roll and kick and comb themselves into silky condition. The usual colour of the domesticated yak is black, more rarely a yellowish brown. A common variety has a white face and white tail. The calves are born in the spring, late April or early May.

Here and there the rivers overflow their banks and form lakes or meres, which in the summer are the haunt of innumerable wild-fowl: bar-headed geese and redshanks nest here, families of ruddy shelducks (the Brahminy duck of India) and garganey teal are seen swimming on the pools. Overhead fly sand-martins, brown-headed gulls, common terns and white-tailed eagles. Near one of these lakes one day I watched at close distance a red fox stalking a pair of bar-headed geese, a most interesting sight, and had the satisfaction of saving the birds by firing a shot in the air with my small collecting gun just as the fox was about to pounce on his intended victim.

Tinki Dzong is a veritable bird sanctuary. The Dzong itself is a rambling fort covering a dozen or so of acres, and about its walls nest hundreds of birds—ravens, magpies, red-billed choughs, tree-sparrows, hoopoes, Indian redstarts, Hodgson's pied wagtails and rock-doves. In the shallow pool outside the Dzong were swimming bar-headed geese and ruddy shelducks, with families of young birds, all as tame as domestic poultry. A pair of white storks was seen here in June, but they did not appear to be breeding. In the autumn the lakes in this neighbourhood are the resort of large packs of wigeon, gadwall and pochard. The Jongpen explained to us that it was the particular wish of the Dalai Lama that no birds should be molested here, and for several years two lamas lived at Tinki, whose special business it was to protect the birds.

Crossing over a pass of about 17,000 feet (Tinki La), the slopes gay with a little purple and white daphne (Stellera), said by the natives to be poisonous to animals, we came to a plain of a different character, miles of blown sand heaped here and there into enormous dunes, on which grows a yellow-flowering gorse. Here, near Chushar, we first met with rose-finches (Severtzoff's and Przjewalsk's) and the brown ground-chough (Podoces humilis): the last-named is a remarkable-looking bird, which progresses by a series of apparently top-heavy bounds, at the end of which it turns round to steady itself; in the middle of June it was feeding its young in nests at the bottom of deep holes in sand or old mud walls.
