550d. Macgillivray’s Seaside Sparrow. 
Passerherhulus maritimus macgillivrai. 
Range. — Coast of South Carolina. Like 
ftsheri but grayer. 
551. Dusky Seaside Sparrow. Passerher- 
bulus nigrescens. 
Range. — Marshes of Indian River near Titus- 
ville, Florida. 
This species is the darkest of the genus, both 
above and below, being nearly black on the 
upperparts. Their habits are like those of the 
others and the eggs are not likely to differ. 
552. Lark Sparrow. Chondestes gramma- 
cus grammacus. 
Lark Sparrow 
Range. — Mississippi Valley from the Plains 
to Illinois and casually farther east, and from 
Manitoba to Texas; winters in Mexico. 
This handsome Sparrow has the sides of the crown and ear 
patches chestnut, and the sides of the throat and a spot on the 
breast, black. They are sweet singers and very welcome birds 
in their range, where they are quite abundant. Their nests 
are generally placed on the ground in the midst of or under a 
clump of weeds or tuft of grass, but sometimes in bushes or 
even trees; they are made of grasses and weeds and the eggs, 
which are usually laid in May, are white marked chiefly 
about the large end with blackish zigzag lines and spots. Size .80 x .60. 
552a. Western Lark Sparrow. Chondestes grammacus strigatus. 
Range.— United States west of the Plains; 
breeds from British Columbia to Mexico. 
This paler and duller colored variety is com- 
mon on the Pacific coast; its habits and nests 
and eggs are like those of the last. 
553. Harris’s Sparrow. 
Zonotrichia querula. 
Range.— Mississippi Valley, chiefly west, 
breeding in Manitoba and Saskatchewan, the 
exact range being unknown. 
Although the birds are 
abundant during migrations, 
they seem to suddenly and 
strangely disappear during 
the breeding season. Sup- 
posed nests have been found 
a few inches above the ground 
in clumps of grass, the eggs 
being whitish, thickly spotted 
with shades of brown. Size .86 x .65.
