THE MOUSTACHED GRASS WARBLER.
Length, 5.75 ; expanse, 7.4 ; wing, 2.45 ; tail, 2.1; tarsus, 0.85 ; bill at front, 0.45.
Bill dark-brown, almost black, paler on lower mandible ; irides, brown to pale-brown; legs dusky-brown, soles pale-yellowish.
A broad conspicuous white stripe from the nostrils over the eyes and ear-coverts ; a dark-brown stripe from in front of under and through the eyes, enveloping the upper portion of the ear-coverts, darker in the males than the females ; the chin, throat, and lower parts, including the lower tail-coverts, white, faintly tinged rufescent on the breast, more strongly so on the flanks about the vent, and, in some specimens, the lower tail-coverts also; the sides, both of the neck and body, tinged with greyish, or in some olivaceous-brown ; the forehead, crown, occiput, and nape, very dark-brown, the feathers tipped and margined with a paler yellowish olive-brown ; in some specimens. these tippings entirely obscure the bases, except on a narrow line immediately above the white eye-streak ; in others, these parts appear to be very dark-brown, regularly striated with the paler olive-brown, while in some the tippings are almost entirely wanting; the back, scapulars, rump, and upper tail-coverts, the same yellowish olive-brown, becoming more rufescent on the lower back, rump and upper tail-coverts; the feathers of the centre of the back with more or less conspicuous dark central shaft streaks.
In some birds the whole back seems regularly striated with dark lines, in others only a few faint darker streaks are visible in the very centre of the back; in some, again, the lower back is much more decidedly rufous. The wings are hair-brown; the primaries very narrowly margined, and tipped on the outer webs, paler; the secondaries and tertiaries and most of the coverts more distinctly margined with a sort of rufescent-olive; the wing-lining and axillaries pure, or nearly pure white; tail feathers somewhat pale hair-brown, obscurely margined with rufescent-olive ; the shafts dull white below.
The Moustached Grass Warbler is a cold weather visitant to Sind ; it does not occur elsewhere within our limits.
