563. Field Sparrow. 
Spizella pusilla pusilla. 
Range. — North America east of the Plains, 
breeding from the Gulf to southern Manitoba 
and Quebec; winters in the Gulf States. 
These are abundant birds 
along roadsides, in thickets, or 
on dry sidehills, where they nest 
indifferently on the ground or in 
hushes, making their nests of 
grass and weed stems. They are 
the birds, whose high piping 
song is most frequently heard 
on hot sultry days in summer. Their eggs are 
laid in May or June; they are pale bluish 
white, speckled and blotched with yellowish 
brown and grayish purple. Size .65 x .50.

563a. Western Field Sparrow. Spizella 
Field Sparrow pusilla aveTiacea, 
Range. — Great Plains from Mexico to Montana, breeding in the northern half 
of its range and wintering in the southern. 
A paler form of the last, whose general habits and eggs are the same as those 
of the eastern bird. 
564. Worthen’s Sparrow. Spizella wortheni. 
Range. — Southern New Mexico southward through central Mexico. 
This pale colored species is the size of the Field Sparrow but has no decided 
markings anywhere. It is a rare bird within our borders and uncommon any- 
where. I am not able to find any material in regard to their eggs.

This slim-bodied, long-tailed species is grayish with a dusky 
streaked, reddish brown patch on the back and a black face, chin 
and throat. Their habits are similar to those of the Field 
Sparrow and their nests are made near the ground in bushes, 
hut the eggs are plain bluish green, about like unmarked 
Chipping Sparrows’ eggs. Size _ 
566. White-winged Junco. Junco aikeni. 
Range. — Breeds in the Black Hills of Da- 
kota and Wyoming; winters in Colorado and 
casually to Kansas. 
This species is like the next 
hut larger and with the wings 
crossed by two white bars. Its 
habits are like those of the com- 
mon Juncos, the nests are placed 
on the ground, concealed under 
overhanging rocks or tufts of 
grass, and the eggs are like 
those often seen of the Slate-colored Junco; 
3 or 4 in number, pinkish white specked and 
spotted with light reddish brown. Size .75 x .55.
