This is very much like the last, but lighter, and is found common in Arizona, New Mexico and southern California. Its favorite nesting place seems to be a bunch of Spanish moss, looping up the ends and weaving it closely together, and forming a pocket inside, which they line with dried grasses and yucca fibers.

BULLOCK ORIOLE.

508. Icterus bullocki. 7½ inches.

This is a western representative of our eastern bird, the Baltimore Oriole, and their ranges overlap each other on the eastern slope of the Rockies. They build a hanging nest, and in the southern part of their range use the Spanish moss and mistletoe for the foundation of the nest, lining the opening with grasses, hair and small fiber. Three or four white eggs, spotted and streaked with shades of brown (.94 × .62). These birds are of great benefit to the small fruit growers in eating the many injurious insects.

RUSTY BLACKBIRD.

509. Euphagus carolinus. 9 inches.

This is a bird of the east, but is found on the eastern slope of the Rockies, and straying into southern California to the Gulf of Mexico. Breeds along the northern borders of the United States, northwest to Alaska. The female is very much lighter than the male, and of a brownish drab color. They build large substantial nests of moss, twigs and grass, lined with finer material of the same, and placed in low bushes or trees only a few feet from the ground. Three to five eggs, pale bluish green, blotched and spotted with brown (.96 × .71).
