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).
