The Brown Rock-Pipit breeds in the Himalayas at suitable elevations from Gilgit, throughout Kashmir, to Garhwal, Kuman, Sikkim and South-West Tibet, while Whistler records it as a breeding bird in the Salt Range.
Within the above area this Pipit maybe found breeding at all elevations between 4,000 and 8,000 feet, and much lower down in the Salt Range. P. Mackinnon also obtained this bird’s nests and eggs below Mussoorie at something under 4,000 feet, while Jesse had a clutch in his collection from near Abottabad at about 3,000 feet.
This bird, like the preceding, is a dweller in the waste lands, preferring rocky slopes with but little vegetation of any kind but with plentiful loose rocks and boulders, under which to nest. At the same time, though it prefers to tuck its nest away in some hole or hollow under, or in, boulders and rocks, it occasionally makes it in a depression in the grass under the shelter of some small bush.
The nest differs in no way from that of the preceding bird, hut is not always made of grass alone. Dodsworth (Journ. Bomb. Nat. Hist. Soc. vol. xxii, p. 799, 1919) describes one nest as. “a shallow cup, composed exteriorly of coarse grass-stems, roots, pieces of sticks, with some moss attached here and there to its sides, and lined with very fine grasses. It measured : diameter of egg-cavity 3", depth of same 1.25" ; external diameter 4.25" ; thickness of sides .65" ; thickness of bottom .5", It was placed in a hole under a tuft of grass.”
Marshall gives the breeding season as “from May till middle of July,” and this agrees with the notes of later collectors. In my own series I have eggs taken from the 28th April (Jesse) to the 10th July (A. E. Jones).
The normal full clutch of eggs is three, rarely four, and some¬times only two. In appearance they are typical Rock-Pipits’ eggs, but more handsome and more varied than those of the other races. In the series collected by Osmaston there are three clutches, which show well the extremes of variation
1. Ground pale grey-brown richly blotched and speckled with dark brown, with secondary inconspicuous markings of lilac-grey and neutral tint.
2. Ground very pale grey marked with small, rather longitudinal blotches of grey and brownish-grey, more numerous at the larger end than elsewhere.
3. Ground pale sea-green, profusely spotted and blotched with blackish-brown, and with secondary spots of neutral tint. These are exceptionally handsome eggs.
Every intermediate form of egg to the above three may be found, the dominant tinge in a series being brown.
In shape and texture they are normal.
Forty eggs average 22.7 x 16.6 mm. : maxima 24.1 x 17.7 and 23.6 x 18.0 mm. ; minima 21.0 x 16.3 and 22.5 x 15.1 mm.
