Range.--North America, breeding north of our borders; winters in northern half of the United States and casually farther south.
All Shrikes are similar in nature and plumage, being grayish above and white below, with black wings, tail and ear patches, and with white outer tail feathers and bases of primaries; the present species may be known by its larger size (length over 10 inches) and wavy dusky lines on the breast. They are bold and cruel birds, feeding upon insects, small rodents and small birds, in the capture of which they display great cunning and courage; as they have weak feet, in order to tear their prey to pieces with their hooked bill, they impale it upon thorns. They nest in thickets and tangled underbrush, making their nests of vines, gra.s.ses, catkins, etc., matted together into a rude structure. During April or May they lay from four to six grayish white eggs, spotted and blotched with yellowish brown and umber; size 1.05 .75.
622. LOGGERHEAD SHRIKE. _Lanius ludovicia.n.u.s ludovicia.n.u.s._
Range.--United States, east of the Plains, breeding north to New England and Illinois; winters in Southern States.
Like the last but smaller (length 9 inches), not marked below and with the ear patches sharply defined. They nest in hedges or thickly tangled brush, showing a predilection for dense thorn bushes, where they place their piles of weeds, gra.s.ses, feathers and rubbish; the four or five eggs are laid in April or May; they are like those of the last, but smaller, averaging .96 .72.

622a. WHITE-RUMPED SHRIKE. _Lanius ludovicia.n.u.s excubitorides._
Range.--North America, west of the Plains, breeding north to Manitoba and the Saskatchewan; winters south to Mexico.
Like the last but paler and the rump white. Their nesting habits and eggs are in every respect like those of the Loggerhead Shrike.
622b. CALIFORNIA SHRIKE. _Lanius ludovicia.n.u.s gambeli._
Range.--Pacific coast north to British Columbia.
Similar to the eastern form but with the breast washed with brownish and with indistinct wavy bars. The eggs cannot be distinguished from those of the others.
622c. ISLAND SHRIKE. _Lanius ludovicia.n.u.s anthonyi._
Range.--Santa Barbara Islands, California. Like the last but smaller and darker. Eggs not distinguishable.
VIREOS. Family VIREONDIDae
623. BLACK-WHISKERED VIREO. _Vireosylva calidris barbatula._
Range.--A Central American species, breeding in Cuba, Bahamas and southern Florida.
Like the Red-eyed Vireo but with a dusky streak on either side of the chin. They build pensile nests of strips of bark and fibres, swung from the forks of branches. The eggs cannot be distinguished from those of the next species, being white, more or less specked about the large end with reddish brown and umber. Size .78 .55.

624. RED-EYED VIREO. _Vireosylva olivacea_.
Range.--United States, east of the Rockies, breeding north to Labrador, Manitoba and British Columbia.
This is the most common of the Vireos in the greater part of its range and is a most persistent songster, frequenting groves, open woods or roadsides. Their eyes are brown, scarcely if any more red than those of any other species and I have yet to see one with red eyes outside of mounted museum specimens. They swing their nests from the forks of trees at any elevation from the ground but usually below ten feet, and I have found them where the bottom rested on the ground; they are made of strips of bark, fibre, etc., and often have pieces of string or paper woven into the sides; they are one of the most beautiful of bird homes and are woven so strongly that old nests hang to the branches for several seasons. Their three or four eggs, often accompanied by one of the Cowbirds, are laid in May or June; they are white, sparingly specked with blackish brown. Size .85 .55.
625. YELLOW-GREEN VIREO. _Vireosylva flavoviridis._
Range.--Southern Texas and southward to South America.
Similar to the Red-eye but greener above and more yellowish on the sides. The nesting habits are the same and the eggs indistinguishable from those of that species.
626. PHILADELPHIA VIREO. _Vireosylva philadelphica_.
Range.--Eastern United States breeding from northern New England and Manitoba northward.
This species is much smaller than the Red-eye (length 5 in.) and is yellowish below, and without black edges to the gray crown. Their eggs do not differ from those of the Red-eyed Vireo except in size, averaging .70 .50.
627. WARBLING VIREO. _Vireosylva gilva gilva._
Range.--North America east to the Plains, breeding north to Labrador.
This Vireo is nearly as abundant as the Red-eye but is not generally as well known, probably because it is usually higher in the trees and more concealed from view. Their nests are like those of the Red-eye, but smaller and usually placed higher in the trees. The birds are even more persistent singers, than are the latter but the song is more musical and delivered in a more even manner, as they creep about among the foliage, peering under every leaf for lurking insects. The eggs are pure white, spotted with brown or reddish brown. Size .72 .52.
