THE DESERT WARBLER.
Length, 4.8 to 4.9 ; expanse, 7 to 7.2; wing, 2 to 2.2; tail, 1.8 to 2 ; tarsus, 0.8; bill at front, 0.33.
Bill pale yellow, dusky on culmen and at tip; irides orange-yellow ; legs and feet pale yellow.
The lores are greyish-white; from the nostril to the upper margin of the eye runs a very narrow yellowish-streak, whiter and less grey than the lores ; this line ceases to be visible in nine out of ten skins, but is sufficiently apparent in the freshly killed bird; a circle of yellowish-white feathers surrounds the eye; forehead, crown, occiput, nape, back, and scapulars, pale fawn-brown; rump and upper tail-coverts pale rufous; central tail-feathers pale rufous, with dark shafts; external lateral feathers wholly white, next pair white on the outer webs, and with a moderately broad white tip to both webs ; the rest of the inner webs dark hair-brown; the rest of the feathers dark hair-brown, margined on the outer webs with pale rufous; the whole of the lower parts white, with, in the freshly killed birds, a just perceptible rufous tinge; wing-lining and axillaries pure white ; wing pale-brown, narrowly margined and tipped with rufescent-white ; the tertiaries pale dingy-rufescent with brown shafts.
Within our limits this Warbler only occurs in the more desertlike portion of Sind and in the Runn of Kutch. It is apparently a permanent resident as Mr. Doig found them breeding in October.
