Plate CLXIV. Fig. 1. Male. Fig. 2. Female.

Wings of ordinary length, with the outer three quills almost equal,

the second longer than the first, which slightly exceeds the fourth;

tail emarginate. Male with the crown of the head deep brownish-red,

the upper parts yellowish-olive, streaked with brown, the rump

greenish-yellow, without streaks; quills dusky brown, primaries edged

with whitish, secondaries with yellowish; tail feathers dusky brown,

margined with greenish-yellow, the outer two with a white patch on the

inner web at the end, sometimes the outer white on both webs at the

end; a bright yellow streak from the nostril over the eye; lore dusky;

ear-coverts brownish-red; lower parts yellow, the sides of the neck,

its lower part, and the sides of the body, streaked with deep red.

Female similar to the male, but with the tints duller and paler, the

red of the head scarcely apparent, and the fore-neck very faintly

streaked. Young dull light greenish-brown, tinged with grey, the head

streaked with dusky; lower parts yellowish-grey, the sides of the neck

and body, with the breast, faintly streaked with greyish-brown.

Plate XV. Male and Female.

Bill much attenuated; outer three quills nearly equal, first or second

longest; tail almost even, with the feathers pointed. Male with the

upper parts light blue, the fore part of the back yellowish-green; two

broad bands of white on the wing, formed by the tips of the secondary

coverts, and first row of small coverts; quills and tail-feathers

dusky, margined with blue; a white spot on the outer three of the

latter; loral space black; both eyelids with a white spot; throat

yellow, with whitish patches, a lunular band of blackish on the fore

neck; breast yellow, spotted with dull orange, the rest of the lower

parts yellowish, fading into white, the sides pale greyish-blue.

Female similar but paler; the loral band wanting; throat, fore neck,

and breast yellow, without the black lunule.

Although the bill of this species is much attenuated, it is not

essentially different in form from that of S. Blackburniæ, and others

of this genus; the wings are similar to those of the rest, and there

seems no reason for setting it apart to form a genus, as has been done

by Bonaparte.

_Male_, 4-1/6, 6-1/2.

From Texas, generally distributed. Exceedingly abundant. Migratory.
