Similar to the last but with white spots on the upper and lower eyelids, black lores, and the black patch on the breast mixed with gray. These ground inhabiting birds are found in tangled thickets and shrubbery where they nest at low elevations, from one to five feet from the ground. Their nests are made of grasses and shreds of bark, lined with hair and finer grasses, and the eggs are white, specked, spotted and blotched with shades of brown and neutral tints; size .72 × .52. Data.--Sonoma, Cal., May 17, 1897. A small nest, loosely made of grasses (wild oats) lined with finer grasses; placed in blackberry vines 14 inches from the ground in a slough in the valley.

MARYLAND YELLOW-THROAT. _Geothlypis trichas trichas._ Range.--Eastern United States; this species has recently been still further sub-divided so that this form is supposed to be restricted to the south Atlantic coast of the United States. The Maryland Yellow-throat is represented in all parts of the United States by one of its forms. They are ground loving birds, frequenting swamps and thickets where they can be located by their loud, unmistakable song of "Witchery, w i t c h e r y, witch." They nest on or very near the ground, making their nests of grass, lined with hair; these are either in hollows in the ground at the foot of clumps of grass or weeds, or attached to the weed stalks within a few inches of the ground. They lay from three to five eggs in May or June; these are white, specked about the larger end with reddish brown and umber, and with shell markings of stone gray. Size .70 × .50. All the sub-species of this bird have the same general habits of this one and their eggs cannot be distinguished from examples of the eastern form; the birds, too, owing to the great differences in plumage between individuals from the same place, cannot be distinguished with any degree of satisfaction except by the ones who "discovered" them. 681a. WESTERN YELLOW-THROAT. _Geothlypis trichas occidentalis._ Range.--This variety, which is said to be brighter yellow below, is ascribed to the arid regions of western United States; not on the Pacific coast. 681b. FLORIDA YELLOW-THROAT. _Geothlypis trichas ignota._ Range.--South Atlantic and Gulf coast to Texas. 681c. PACIFIC YELLOW-THROAT. _Geothlypis trichas arizela._ Range.--Pacific coast from British Columbia southward. 681e. SALT MARSH YELLOW-THROAT. _Geothlypis trichas sinuosa._ Range.--Salt marshes of San Francisco Bay. [Illustration 414: White.] [Illustration: Maryland Yellow-throats.
