Fig, 4. COTURNICULUS PASSERIN US— Yellow-winged Sparrow. 
The Yellow-wingecl Sparrow is a resident of Ohio from April until September. In some localities it 
is quite common, in some, it is but moderately plentiful, while in other sections, equally well adapted to 
its wants, it is rare. About Circleville it is neither common nor rare, being just numerous enough to 
escape either adjective. Two broods are frequently reared by a single pair during the summer. 
LOCALITY : 
It inhabits clover and grass fields, and in such localities builds its nest. It associates with the 
Black-throated Bunting and Bay-winged Bunting, the three species often building near each other in the 
same field. 
POSITION : 
The nest is placed on the ground at the foot-stalks of a bunch of red clover, or in a tussock of grass 
or of small weeds. Every nest which I have found has rested in a depression in the earth, similar to 
the nest of the Bay-winged Bunting. 
MATERIALS: 
A nest before me is composed of a foundation of rough grasses and weed-stems, a superstructure of 
similar but better selected material, and a lining of horse-hair and fine bleached grasses. Its external 
diameter is four and one-eighth inches ; its external depth is one and seven-eighths inches. The diameter 
of its cavity is two and one-half inches ; its depth of cavity is Seven-eighths of an inch. The structure is loosely 
put together and displays but little skill in workmanship, it is, however, a fair example of the archi- 
tecture of this species. 
EGrGrS : 
The complement of eggs consists of four or five. They measure in long-diameter from .70 to .74 of 
an inch, and in short-diameter from .56 to .59 of an inch. The ground-color of the shell is white. The 
markings consist of blotches, spots, and speckles of reddish-brown; the deep shell-marks appear lavender 
or neutral tint. Three eggs from as many sets are marked and measure as follows: No. 1. Ground-color 
white ; base thickly marked with confluent blotches, spots, and speckles of reddish-brown, some of which 
are much darker in shade than others. Remainder of egg is sparingly dotted and speckled with same 
color, and in addition there are several cloudy patches made up of a number of very faint gray blotches 
and speckles. Deep shell-marks are few in number. Size, .53 x .70. No. 2. Ground-color white. Mark- 
ings consist of brown-madder blotches, spots, and speckles, the majority of these form a wreath about the 
crown, the remainder are scattered irregularly over rest of shell. Deep shell-marks are neutral tint, they
