From the Dhakuri pass the path descends about 2000 feet, and then follows the valley of the Pindari river. The scenery here is magnificent. Unlike that of the Sarju, this valley is narrow. It is not much cultivated; amaranthus is almost the only crop grown. The villages are few and the huts which constitute them are rudely constructed. The cliffs are very high, and rise almost perpendicularly, like giant walls, so that the numerous feeders of the river take the form of cascades, in many of which the water falls without interruption for a distance of over 1000 feet. The Kuphini river joins the Pindar 8 miles from its source. Beyond the junction the path to the glacier crosses to the left bank of the Pindar, and then the ascent becomes steep. During the ascent the character of the flora changes. Trees become fewer and flowers more numerous; yellow colt's-foot, dandelions, gentians, Michaelmas daisies, columbines, centaurias, anemones, and edelweiss grow in profusion. Choughs, monal pheasants, and snow-pigeons are the characteristic birds of this region. Thus the birds of the Himalayas inhabit a country in every respect unlike the plains of India. They dwell in a different environment, are subjected to a different climate, and feed upon different food. It is therefore not surprising that the two avifaunas should exhibit great divergence. Nevertheless few people who have not actually been in both localities are able to realise the startlingly abrupt transformation of the bird-fauna seen by one who passes from the plains to the hills. The 5-mile journey from Rajpur to Mussoorie transports the traveller from one bird-realm to another. The caw of the house-crow is replaced by the deeper note of the corby. Instead of the crescendo shriek of the koel, the pleasing double note of the European cuckoo meets the ear. For the eternal _coo-coo-coo-coo_ of the little brown dove, the melodious _kokla-kokla_ of the hill green-pigeon is substituted. The harsh cries of the rose-ringed paroquets give place to the softer call of the slaty-headed species. The monotonous _tonk-tonk-tonk_ of the coppersmith and the _kutur-kutur-kutur_ of the green barbet are no more heard; in their stead the curious calls of the great Himalayan barbet resound among the hills. The dissonant voices of the seven sisters no longer issue from the thicket; their place is taken by the weird but less unpleasant calls of the Himalayan streaked laughing-thrushes. Even the sounds of the night are different. The chuckles and cackles of the spotted owlets no longer fill the welkin; the silence of the darkness is broken in the mountains by the low monotonous whistle of the pigmy-collared owlet.
