stalks, bark strips, grasses and moss, lined with fine black rootlets. They are found at elevations of from two to ten feet above the ground. Like the Wood Thrush the birds are tame while sitting on the nest and will allow a very close approach, without taking alarm; nests are frequently found which are made almost entirely out of green moss and are very handsome structures. Their three to five eggs are laid in May or June; they are greenish blue, spotted with brown of varying shades. Size .92 × .65. Data.--Eureka, California, July 6, 1899. Nest in a fir tree, 5 feet from the ground; made of moss and strips of redwood bark. 4 eggs.

758a. OLIVE-BACKED THRUSH. _Hylocichla swainsoni._

Range.--Eastern North America, breeding chiefly north of the United States, but locally in the northern parts, and abundantly in mountain ranges.

The nesting habits and eggs of this eastern representative of the last species are like those of that bird in all respects and the eggs cannot be distinguished from those of _ustulatus_.

758b. OLIVE-BACKED THRUSH. _Hylocichla œdica_.

Range.--California and southern Oregon.

Nesting habits and eggs identical with those of _ustulatus._

759. ALASKA HERMIT THRUSH. _Hylocichla guttata guttata._

Range.--Pacific coast from British Columbia to Alaska. Winters in Mexico.

The Hermit Thrushes can readily be identified from any other by the reddish brown tail which is in marked contrast to the color of the back. The nesting habits and eggs of this species are precisely like those of the eastern Hermit Thrush, which is a sub-species of this.

759a. AUDUBON'S HERMIT THRUSH. _Hylocichla guttata auduboni._

Range.--Rocky Mountain region of the United States. Winters in Central America.

The nesting habits of this bird are like those of the next except that it more frequently nests in bushes above the ground. The eggs are not distinctive.

759b. HERMIT THRUSH. _Hylocichla guttata pallasi._

Range.--Eastern North America, breeding in northern United States and north to Labrador; winters in southern United States.

This species, which is noted for its sweet and musical song, frequents damp swamps and thickets where it builds its nest either on the ground or near it, like that of the Wilson Thrush; it is made of shreds of bark, grasses, leaves and rootlets, lined with fine rootlets; the three or four eggs, which are deposited in May or June, are bluish green and cannot, with certainty, be distinguished from those of the Veery; size .85 × .65.

759c. DWARF HERMIT THRUSH. _Hylocichla guttata nanus._

Range.--Pacific coast of United States, from Washington, southward.

The nesting habits and eggs of this slightly smaller and duller colored variety are like those of the other Hermit Thrushes.

760. RED-WINGED THRUSH. _Turdus musicus._

Range.--An Old World species, accidentally straying to Greenland.

This common European bird nests at low elevations in bushes or trees, laying four or five bluish green eggs, spotted with reddish brown; size 1.05 × .75.

761. ROBIN. _Planesticus migratorius migratorius._

Range.--North America east of the Rockies, breeding from the middle portions of the United States, north to the Arctic Ocean.

These common birds nest in trees about houses, in orchards, open woods, in corners of fences, on blinds on houses, and in fact almost every conceivable position. Their nests are made of grasses, firmly cemented together with mud and lined with finer grasses; when placed in trees they are generally firmly saddled in crotches and may be found at any height, from on the ground to sixty feet above it. Their eggs are greenish blue; size 1.15 × .80. Eggs may be found at any time from May until July or August as they raise several broods a season.

Page 447

761b. SOUTHERN ROBIN. _Planesticus migratorius achrusterus._

Range.--The Carolinas and Georgia.

The eggs of this bird, which is said to be smaller and duller colored than the northern variety, show no differences in any respect.

762. SAN LUCAS ROBIN. _Planesticus confinis._

Range.--Southern Lower California.

This is a very much paler form of the American Robin; its eggs probably will not differ from those of the others.

[Illustration 449: J. B. Pardoe. NEST AND EGGS OF ROBIN.] [Illustration: right hand margin.]

Page 448

763. VARIED THRUSH. _Ixoreus nævius nævius._

Range.--Pacific coast from northern California to Alaska; south to Mexico in winter.

These handsome birds breed abundantly in Alaska and locally in mountain ranges south to northern California. They nest at low elevations in trees, making them of moss, twigs, weeds and grasses, forming a flat shallow structure. Their eggs are greenish blue sharply but sparingly spotted with dark brown; size 1.12 × .80. Data.--Delta of Kowak River, Alaska, June 11, 1899. Four eggs. Nest 12 feet from the ground, against the trunk of a slender spruce and supported by a clump of stiff twigs.

763a. NORTHERN VARIED THRUSH. _Ixoreus nævius meruloides._

Range.--Interior of western North America, breeding from British Columbia to Alaska. Its habits and eggs do not differ from those of the last.

764. SIBERIAN RED-SPOTTED BLUETHROAT. _Cyanosylvia suecica robusta._

Range.--Northern Asia; casually to Alaska.

This beautiful foreigner nests on the ground and lays four to six greenish blue eggs, spotted with reddish brown; size .75 × .50.

765. WHEATEAR. _Saxicola œnanthe œnanthe._

Range.--Asia; casual in Alaska in summer; nesting habits and eggs like the next.

765a. GREENLAND WHEATEAR. _Saxicola œnanthe leucorhoa._

Range.--Europe and Greenland; casual on the Atlantic coast of North America.

This very abundant Old World species is a common breeding bird in Greenland and probably also in Labrador. They nest in crevices of quarries, holes in the ground, or stone walls, making a rude nest of weeds, moss or grasses, lined with hair or feathers, and during May lay from four to six pale greenish blue eggs; size .90 × .60.

766. BLUEBIRD. _Sialia sialis sialis._

Range.--Eastern United States, breeding from the Gulf to southern Canada. Winters in the southern half of the United States.

These familiar birds build in cavities in trees, usually below 20 feet from the ground, crevices among ledges, bird boxes and in any suitable nook they may discover about buildings, providing that English Sparrows do not molest them. They raise several broods a year, commencing in April when they lay from three to six pale bluish white eggs (rarely pure white); size .80 × .60. The cavities of their nesting sites are lined with grasses and feathers usually, although I have found the eggs on the unlined bottom of cavities in trees.

766a. AZURE BLUEBIRD. _Sialia sialis fulva._

Range.--This pale variety is found in southern Arizona and southward.

Its nesting habits are the same and the eggs are indistinguishable from the last.

767. WESTERN BLUEBIRD. _Sialia mexicana occidentalis._

Range.--Pacific coast from Lower California to British Columbia.

The Western Bluebird is as common and familiar in its range as the common Bluebird is in the east. It nests in similar locations and its eggs are scarcely distinguishable, although averaging a trifle darker in shade; size .80 × .60.

767a. CHESTNUT-BACKED BLUEBIRD. _Sialia mexicana bairdi._

Range.--Rocky Mountain region from Mexico to Wyoming.

The nesting habits or eggs of this brighter colored bird do not differ from those of the last species.

767b. SAN PEDRO BLUEBIRD. _Sialia mexicana anabelæ._

Range.--San Pedro Martir Mountains in Lower California.

The eggs of this variety will not in all probability be any different from those of the preceding Bluebirds.

768. MOUNTAIN BLUEBIRD. _Sialia currucoides._

Range.--Rocky Mountain region, breeding from New Mexico north to Great Slave Lake; winters in southwestern United States and Mexico.

This azure blue species is common in the greater part of its range and is found west to the Sierra Nevadas in California. Like the eastern Bluebird they nest in holes in trees or anywhere that they can find a suitable cavity or crevice. Their eggs are slightly larger than those of the other Bluebirds and have a slight greenish tint; size .85 × .64.
