The Veery is very abundantly distributed in woodland, either moist or dry, and nests on the ground or within a very few inches of it, usually placing its structures of woven bark strips and grasses, in the midst of a clump of sprouts or ferns. The three or four eggs which they lay in May or June are bluish green, much darker than those of the Wood Thrush, and nearly the color of those of the Catbird. Size .90 × .65. 756a. WILLOW THRUSH. _Hylocichla fuscescens salicicola._ Range.--Rocky Mountain region, north to British Columbia. The nests and eggs of this similar bird do not differ from those of the last. 757. GRAY-CHEEKED THRUSH. _Hylocichla aliciæ aliciæ._ Range.--Breeds from Labrador to Alaska; winters south to Central America. The nesting habits and eggs of this species are very similar to those of the following sub-species and the same description will answer for both. 757. BICKNELL'S THRUSH. _Hylocichla aliciæ bicknelli._ Range.--Breeds in the Catskills, White Mountains and Nova Scotia. These birds, which are practically identical with the preceding, build their nests at low elevations in trees, usually evergreens when present, making them of twigs, moss and rootlets, lined with fine grasses. The eggs, which are laid during May or June, are pale greenish blue, spotted and blotched with pale brown or russet. Size .88 × .64. Data.--Seal Island, Nova Scotia, June 3, 1901. Nest of green moss and rootlets, in a spruce, 5 feet from the ground. 758. RUSSET-BACKED THRUSH. _Hylocichla ustulata ustulata._ Range.--Pacific coast, breeding in Oregon and Alaska; winters in Central America. This species is very abundant in moist thickets throughout its range, nesting in bushes and low trees, and making them of weed [Illustration 445: Wood Thrush.] [Illustration: Wilson's Thrush.] [Illustration: Greenish blue.] [Illustration: right hand margin.] Page 444 [Illustration 446: WOOD THRUSH.] Page 445 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_.
