236. 1. Lanius borealis, Vieill. Great American Shrike.

Plate CXCII. Male and Female.

Fourth quill longest, third little shorter, second shorter than sixth,

first half the length of second; tail long, graduated; bill

brownish-black at the end, paler towards the base; upper parts light

ash-grey, the ends of the scapulars and the upper tail-coverts

grayish-white; a streak of whitish over the eye; loral space and a

patch behind the eye brownish-black; first row of smaller

wing-coverts, larger coverts, and quills, brownish-black; secondary

quills and coverts edged and tipped with whitish; base of primaries

white, forming a conspicuous patch, when the wing is extended;

tail-feathers brownish-black, outer web of lateral feathers, and more

than a third of its inner web from the tip, white; the extremities of

all the rest, excepting the middle two, also white, gradually

occupying less extent on the inner feathers; lower parts

greyish-white, the fore part of the breast tinged with brown, and

faintly marked with transverse undulating lines of dark grey, as are

the sides. Female similar, but with the head and neck slightly tinged

with brown, and the lower parts more banded.

_Lanius Excubitor_ differs in being considerably smaller, and in

having the white on the wings and tail more extended, the bases and a

great portion of the inner webs of the secondaries, except the inner

three, being of that colour, as well as the bases of the primaries,

and forming a conspicuous spot when the wing is closed, and the outer

tail-feathers being often white in their whole length.

_Male_, 10-2/12, 14-2/12.

Breeds from Pennsylvania northward. During winter, migrates westward

to the Mississippi, and as far south as Natchez. Not uncommon.
