Vernacular names. None recorded.
Description. Differs from the .Rufous Rock-Pipit in being a paler brown above with no very definite blackish centres to the feathers of these parts; below it is duller and less rufous, especially about the vent and under tad-coverts; the markings on the breast and flanks are not so well-defined.
Colours of soft parts as in the Rufous Rock-Pipit.
Measurements. Wing 91 to 101 mm.; tail 76 to 86 mm.; tarsus 28 to ttO mm.; culmen 15 to 16 mm.
Distribution. Breeding in the Himalayas from Gilgit to Sikkim and South-West Tibet. In Winter it occurs South to Sind, the Bombay Presidency, Khandesh, Northern Deccan, Nagpur, Hazaribagh, Assam, Chin Hills and Southern Shan States. Jerdon's records of this bird from Jalna probably refer partly to this bird and partly to the previous one.
Nidification. The Brown Rock-Pipit breeds from April to June between 4,000 and 8.000 feet in the Himalayas and at much lower elevations in' the Salt Range ( Whistler). The nest is the usual rough cup of grass, lined either with finer grass or with grass and hair, placed under shelter of a rock or bush in open grass-land or more barren patches. The eggs number three or four and have a stone-coloured or white ground with innumerable small spots or speaks of sienna-brown, grey-brown or reddish-brown all over this surface. Thirty eggs average 22.8 x 16.6 mm.: maxima 24.1 X 17.7 and 23.6 x 18.0 mm.; minima 21.0 X 16.3 and 22.3 x 15.1 mm.
Habits. This is a Pipit both of open grass-lands, surrounded by forests, such as those of Murree and other parts of the Himalayas and of the more rocky barren parts of the Punjab. It is a migratory bird in the true sense of the word, leaving the higher hills entirely in the Cold Weather.
