RUSTY BLACKBIRD. 
510. Euphagus carolinus. 9% inches. 
Male glossy black; female grayish; both sexes in 
winter with most of the head and breast feathers tipped 
with rusty. In the United States we know these birds 
chiefly as emigrants; but a few of them remain to breed 
in the Northern parts. Their songs are rather squeaky 
efforts, but still not unmusical. These birds are found 
east of the Rockies. 
BREWER BLACKBIRD. 
510. Euphagus cyaneocephalus. 10 inches. 
Male with a glossy purplish head and greenish-black 
body; female gray ish brown. This is the Western rep- 
resentative of the preceding; it is most abundant west 
of the Rockies, but is also found on the Plains. Its dis- 
tribution is not so northerly and it nests commonly in 
its United States range. Their eggs are whitish, very 
profusely spotted and blotched with various shades of 
brown (1.x.75).
