550d. MACGILLIVRAY'S SEASIDE SPARROW. _Passerherbulus maritimus
macgillivrai._

Range.--Coast of South Carolina. Like fisheri but grayer.

551. DUSKY SEASIDE SPARROW. _Passerherbulus nigrescens._

Range.--Marshes of Indian River near Titusville, 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 grammacus grammacus._

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 common 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. Supposed 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 .85 x .65.
