CHAR. _Average plumage._ Ground-color of the upper parts bright orange-ochraceous; this overlaid in cloudings, on nearly the whole of the surface, with a delicate mottling of blackish and white; the mottling continuous on the back and inner scapulars, and on the ends of the primaries more faint, while along their edges it is more in the form of fine dusky dots, thickly sprinkled. Each feather of the mottled surface (excepting the secondaries and primaries) has a medial dash of black, enclosing a roundish or cordate spot of white near the end of the feather; on the secondaries and primaries, the mottling is condensed into obsolete transverse bands, which are about four in number on the former and five on the latter; primary coverts deeper orange-rufous than the other portions, the mottling principally at their ends. Tail orange-ochraceous, finely mottled—most densely terminally—with dusky, fading into whitish at the tip, and crossed by about five distinct bands of mottled dusky. Face white, tinged with wine-red; an ante-orbital spot of dark claret-brown, this narrowly surrounding the eye; facial circle, from forehead down to the ears (behind which it is white for an inch or so) soft orange-ochraceous, similar to the ground-color of the upper parts; the lower half (from ears across the throat) deeper ochraceous, the tips of the feathers blackish, the latter sometimes predominating. Lower parts snowy-white, but this more or less overlaid with a tinge of fine orange-ochraceous, lighter than the tint of the upper parts; and, excepting on the jugulum, anal region, and crissum, with numerous minute but distinct specks of black; under surface of wings delicate yellowish-white, the lining sparsely sprinkled with black dots; inner webs of primaries with transverse bars of mottled dusky near their ends. _Extreme plumages._ Darkest (No. 6,884, ♂, Tejon Valley, Cal.; “R. S. W.” Dr. Heermann): There is no white whatever on the plumage, the lower parts being continuous light ochraceous; the tibiæ have numerous round spots of blackish. Lightest (No. 6,885, same locality): Face and entire lower parts immaculate snowy-white; facial circle white, with the tips of the feathers orange; the secondaries, primaries, and tail show no bars, their surface being uniformly and finely mottled. _Measurements_ (♂, 6,884, Tejon Valley, Cal.; Dr. Heermann). Wing, 13.00; tail, 5.70; culmen, .90; tarsus, 2.50; middle toe, 1.25. Wing-formula, 2, 1–3. Among the very numerous specimens in the collection, there is not one marked ♀. The extremes of a large series are as follows: Wing, 12.50–14.00; tail, 5.70–7.50; culmen, .90–1.10; tarsus, 2.55–3.00.
