BULLOCK ORIOLE. 
508. Icterus bullocld. 7 1 /2 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 x 
.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 x .71).
