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.
