GRINNELL WATER THRUSH.

675a. Seiurus noveboracensis. 5½ inches.

Range.—From Alaska to Mexico, breeding in the northern portions. They are a quiet bird, solitary in habits, nesting in stumps near the ground or among roots of fallen trees. Four white eggs, spotted and blotched with brown and lilac (.80 × .60).

MACGILLIVRAY WARBLER.

680. Oporornis tolmiei. 5½ inches.

Range.—Western North America, from British Columbia to southern California, breeding throughout its range. They are common warblers of the Pacific coast, to be found on or near the ground in thick shrubbery, where they build their nests within a few feet of the ground. This is made of grasses and shreds of vines, and lined with finer grasses and hair. Four eggs are laid, white, spotted and quite heavily marked with shades of brown (.72 × .52).

WESTERN YELLOW-THROAT.

681a. Geothlypis trichas occidentalis. 5¼ inches.

Range.—Western North America, from British Columbia south to Arizona, but not near the Pacific coast. It is one of the seven or eight forms of the Maryland Yellow-throat, the greatest difference in them being in the locality in which they are found. They place their nest in a clump of grass, well concealed, laying usually four white eggs, with few spots of brown (.70 × .50).
