Colovr.-. The tints of this bird are of a dull and somewhat sombre cast.
The chin, the throat, and a space round the eyes, are bare, and of a colour
intermediate between lake and vermilion red ; the top of the head is broccoli-
brown ; the upper and lateral parts of the neck umber-brown, or blackish
brown, with white variegations, the latter in the shape of short narrow stripes,
one upon the outer, and another upon the inner edge, of each feather. The
interscapulars, back, and shoulders, pale yellowish brown, more or less
glossed with grey, and each feather has a dark stripe in the course of the
shaft, and some fine brown undulations, or narrow oblique lines upon both
vanes. Under parts a rusty, or yellowish grey, the breast and lower part of
the neck darkest, and each feather is marked, in the course of the shaft, by a
dark umber-brown stripe, which increases in width towards its hinder extremity
; in some lights many of the feathers appear distinctly margined with silvery
grey: the feathers of the belly are each marked, besides, by four additional
narrow stripes, two upon the outer edge of each vane, the outermost
stripe bright chesnut, the innermost yellowish white, and not always very distinctly
defined : the feathers of the flanks, thighs, and vent, have only the
central brown stripe, but the vahes are finely mottled with minute brown dots,
or delicate undulated lines. The primary wing coverts are umber-brown ; the
primary and secondary quill feathers yellowish brown, the vanes of the latter
towards their outer edges, and most of the tertiaries dusky buff, finely mottled,
or undulated with brown. Tail dusky buff, freely variegated with oblique,
waved, narrow brown lines. Upper mandible dark horn colour; eyes
dark brown; legs, toes, spurs, and nails, greenish-brown.
F orm, &c.—Typical; bill lengthened, strong, and considerably arched, with
the edges of the upper mandible overlying the lower, and inclosing it.
Chin, throat, and space round the eyes, denuded of feathers, and slightly
