SPARROW HAWK (Falco sparverius.) 
The Sparrow Hawk is the smallest and most beautiful of the 
American hawks. The length of the bird is from 9 to 12 inches and 
the outspread wings measure from 18 to 23 inches. During migra- 
lions in the spring and autumn and throughout the summer months 
the Sparrow Hawk is common in nearly all sections of this State, 
except perhaps in the heavily wooded mountainous districts where, 
according to my experience, the species is rather rare. In southern 
Pennsylvania, especially in Chester, Delaware, Lancaster and York 
counties, this bird is of frequent occurrence as a winter resident, 
but in the central and northern counties of our State it is regarded 
as a rather unusual winter sojourner. In southeastern Pennsyl- 
Vania where this species is a common summer resident they begin 
nesting in April. The eggs, usually five in number, are deposited in 
hollow trees, generally the deserted hole of a woodpecker. The 
eggs measure about 1.533 by 1.15 inches and are of a whitish or pale. 
yellow brown color, blotched all over with dark brown. 
When the young or eggs are disturbed the parent birds will some-
