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 × .65.

WHITE-CROWNED SPARROW. _Zonotrichia leucophrys leucophrys._ Range.--North America breeding abundantly in Labrador and about Hudson Bay, and casually in northern New England and in western United States in the Rockies and Sierras. Winters along our Mexican border and southward. A handsome species with a broad white crown bordered on either side by black, and with a white superciliary line and black lores; the underparts are uniform grayish white. These birds appear to be nowhere as common as the White-throated Sparrows with which they associate during migrations and in the breeding grounds. They build on the ground, generally near the edges of woods or in clearings, and lay from four to six eggs similar but larger, and with as much variation in markings as those of the Song Sparrow; pale greenish blue, spotted and splashed with reddish brown and grayish. Size .90 × .65. Data.--Nachook, Labrador, June 10, 1897. Nest of fine grasses on the ground in a clump of grass. 554a. GAMBEL'S SPARROW. _Zonotrichia leucophrys gambeli._ Range.--Rocky Mountains and westward from Mexico to Alaska, breeding chiefly north of the United States. This bird is like the last but the lores are white. Its nesting habits and eggs cannot be distinguished from those of the former. 554b. NUTTALL'S SPARROW. _Zonotrichia leucophrys nuttalli._ Range.--Pacific coast from British Columbia to Lower California. Similar to the last but smaller and browner above; nests on the ground or in bushes, the eggs not being distinguishable from those of the other White-crowns. 557. GOLDEN-CROWNED SPARROW. _Zonotrichia coronata_. Range.--Pacific coast from Mexico to Alaska, breeding chiefly north of our borders. This species has the crown yellow, bordered by black on the sides. Their habits are like those of the White-crowned Sparrows, they feeding upon the ground among the dead leaves, and usually being found in flocks and often accompanied by many of the last species. They nest upon the ground or in low bushes, and in May or June lay three or four eggs very similar to the last. Size .90 × .65.
