360. Sparrow Hawk. Falco sparverius. 
Range. — North America, east of the Rocky 
Mountains and north to Hudson Bay; winters 
from the middle portions of the United States, 
southward. 
This beautiful lit- 
tle Falcon is the 
smallest of the Am- 
erican Hawks, being 
only 10 inches in 
length. They are 
very abundant in the 
east, nesting any- 
where in cavities in 
trees, either in 
woods or open fields. 
The eggs are gener- 
ally deposited upon 
the bottom of the 
cavity with no lining; they are creamy or yel- 
lowish buff in color, sprinkled, spotted or 
blotched in endless variety, with reddish brown. 
Size 1.35 x 1.10. These birds are very noisy, 
especially when the young are learning to fly, uttering a loud, tinkling, “killy, 
killy, killy.” They have a very amiable disposition, and frequently nest har- 
moniously in the same tree with other birds, such as Flickers and Robins.
