THE SOCIAL LARK.
Length, 6.25 ; wing, 4; tail, 2.25 ; tarsus, 0.8. Bill whitish-horny, dusky on culmen ; irides dark-brown ; legs brownish.
Upper parts pale rufescent-sandy, streaked with dusky, a stripe over the eye, and the whole under parts fulvous-white, tinged with earthy-brown on the breast, which is spotless in some, in a few slightly spotted; wings dusky-brown, with fulvous edgings, broader and deeper colored on the tertiaries, and on the tips of the coverts, and with a whitish edge to the first developed primary ; tail dusky, the penultimate feather having the outer web wholly white to near the base, and also some of the inner web. In old or worn plumage the dusky tinge prevails on the back; the breast has some narrow dusky streaks, and a patch of the same appears on each side of the lower part of the foreneck ; this is also slightly observable in newly-moulted specimens.
The Social Lark is excessively common during the cold weather, in every portion of the region.
