These are a North American bird, and great travelers in large flocks all over the country, separating at breeding time, and mating up, with a pair or two selecting some orchard or suitable locality to remain during nesting time. They breed throughout the northern United States and north into Canada. Their nests are placed in almost any kind of tree, on horizontal limbs, made of twigs, rootlets, string and grass, in which they lay usually four eggs of a dull grayish color, spotted with dark brown, mostly about the larger end (.85 × .60).
PHAINOPEPLA. 620. Phainopepla nitens. 7½ inches.
These are found from central California to Texas and into Mexico. In habits they are very much like the preceding, and the female is quite similar in looks, while the male is a rich shining blue black, with a long pointed crest, and a white patch on the wings. Their food consists of insects and small berries. They build loosely constructed nests, with a more compact lining of plant down. They lay two or three eggs of a light gray, spotted with brown (.88 × .65).
NORTHERN SHRIKE. 621. Lanius borealis. 10 inches.
One of the largest of the family in the United States, the breast being barred with wavy lines of gray above the paler gray, with the wings and tail having much white, showing especially in flight. They are bold birds; carnivorous in their habits, living upon other small birds, insects and small rodents. In winter they have been known frequently to live about cities, catching the English Sparrows in the parks and city streets. They tear their food to pieces with their bill, which is shaped similar to that of a hawk’s, while their feet are small and weak, not at all resembling the hawk’s feet. Their nests are placed in thickets or thorny bushes, and are made of shreds of vines, grasses and plant down. Four to six grayish white eggs are laid, these being spotted and blotched with shades of brown (1.05 × .75).
CALIFORNIA SHRIKE. 622b. Lanius ludovicianus gambeli. 8 inches.
In size the same as the White-rumped Shrike, and in habits and general appearance much the same, being somewhat darker, more on the under parts and sides. Eggs similar but smaller.
RED-EYED VIREO. 624. Vireosylva olivacea. 6 inches.
One of the most common of the family throughout its range, from the eastern slope of the Rockies over the United States. Wherever they may be found, their song is heard continuously during the day, from early morning until late in the evening, it consisting only of two or three notes, first a rising inflection, then a falling, and repeated over and over, even while they are feeding. The nests are placed within a few feet of the ground on an overhanging limb, suspended from a fork, and made of strips of bark, plant fiber and often with pieces of string and paper included in its construction. Three or four eggs are white, specked sparingly with brown (.85 × .55). This is one of the favorite nests in which the Cowbird deposits its eggs.
WARBLING VIREO. 627. Vireosylva gilva. 5½ inches.
These are nearly as common as the above, but probably not as well known, as they keep well up in the tops of the taller trees, where they also build their nests, very much the same as the Red-eye. Their song is much more pleasant. Four eggs, like above (.72 × .52).
CASSIN VIREO. 629a. Lanivireo solitarius cassini. 5 inches.
To be found west of the Rockies from British Columbia south to Lower California and Mexico. In southern California, it is found breeding much more commonly than the Western Warbling Vireo, placing its nest high in the oaks and coniferous trees. It belongs to the same musical family, keeping up its song from morning until night. The nest is made of similar material to the previous, and the eggs are the same, except in size (.75 × .58).
BLACK-CAPPED VIREO. 630. Vireo atricapillus. 4½ inches.
A smaller variety, the male marked with a black cap. Breeds in Texas, north to Kansas. Winters in Mexico (not illustrated).
HUTTON VIREO. 632. Vireo huttoni. 4½ inches.
Similar to last, without the black cap. Found in central and southern California. Nesting habits similar to others of the family. Eggs white with a few spots of brown about the larger end (.70 × .50).
ANTHONY VIREO. 632c. Vireo huttoni obscurus. 4¼ inches.
Like Hutton, but a trifle smaller and darker. Found from British Columbia to southern California, breeding in Oregon (not illustrated).
LEAST VIREO. 633a. Vireo belli pusillus. 4¼ inches.
Much like the last, and found nesting in southern California, Texas and Arizona. Their nest is a neat, compact, cup-shaped structure, made of shreds of vines and fine roots, and lined with fine grass. The four eggs are white, spotted finely with brown about the larger end (.70 × .80).
GRAY VIREO. 634. Vireo vicinior. 5½ inches.
Found in the southwestern United States, from western Texas, and southern California, into Mexico. They are not uncommon birds in the mountains of Arizona, where they nest in low bushes or trees, building their nest similar to the Red-eyed vireo in the horizontal fork of some overhanging limb, within a few feet from the ground. Usually four white eggs, which are finely spotted with brown about the larger end (.72 × .53).
Family MNIOTILTIDÆ—WOOD WARBLERS.
BLACK-AND-WHITE WARBLER. 636. Mniotilta varia. 5¼ inches.
This eastern bird, with its black and white markings, is found in southern Texas, and has been seen accidental in California and Washington (not illustrated).
LUCY WARBLER. 643. Vermivora luciæ. 4 inches.
Range.—Southwestern United States and Mexico. It breeds quite commonly in Arizona, where it builds in almost any situation, in the loose bark on tree trunks, in deserted woodpecker holes, in the cactus or in small bushes near the ground. The nest is made of fine grass, leaves and feathers, in which they lay usually four white eggs, spotted and wreathed with brown about the larger end (.60 × .50).
