NORTH AMERICAN BIRDS EGGS. 259 



554a. Intermediate Sparrow. Zonotrirlini Jtucophrys 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 fggs 

 cannot be distinguished from those of the former. 

 554b. Nuttall Sparrow. Zonotrichia leucophrys nuttaUi. 



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 Spar- 

 rows, 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 sim- 

 ilar to the last. Size .90 x .65. I Pale greenish blue.] 



558. White-throated Sparrow. Zonotrichia albicollis. 



Range. North America east of the Plains and breeding from the northern tier 



of states northward; winters from the Middle States southward. 



To my mind this is the most beautiful of Sparrows, with its bright and softly 



blended plumage and the pure white throat boldly contrasting with its grayish 

 breast and sides of the head; the lores are adorned with a 

 bright yellow spot. They are one of the most abundant of 

 Sparrows in the east during migrations and their musical 

 piping whistle is heard from hedge and wood. They nest most 

 abundantly north of our borders, laying their three or four 

 eggs in grass lined hollows in the ground, or more rarely 

 in nests in bushes. The eggs are white or bluish white, 

 thickly spotted with several shades of brown. Size .85 x .62. 



They nest most often in thickets or on the edge of swamps, in just such places 



as they are met with on their migrations. 



559. Tree Sparrow. Spizcllu niontlcola. 



Range. North America east of the Plains, breeding north of the United States 

 to the Arctic coast, east of the Rockies; winters within the United States. 



A larger bird but somewhat resembling the common Chipping Sparrow, but 

 browner above, with a black spot on the breast and no black on the head. 

 They are quite hardy birds.and winter in many of the northern 

 states where they may be found in flocks upon the snow, feeding 

 on seeds of protruding weeds. They breed very abundantly in 

 Labrador and about Hudson Bay, placing their green nests in 

 hollows on the ground or moss; their three or four eggs are 

 greenish white, abundantly speckled all over the surface with red- 

 dish brown. Size .80x .55 Data. Foothi-lls of Black Mountains, , 

 McKenzie River, Arctic America, June 13, IS'.U). Nest on the L ' 

 ground under a tuft of grass on level plain ; made of grasses and moss and lined 

 with feathers. Collector, I. O. Stringer. 

 559a. Western Tree Sparrow. Spizdla nionfiroJa oclirtirru. 



Range. North America west of the Plains, breeding in Alaska anil wintering 

 to Mexico. A paler form of the last, the nesting habits and eggs of which are 

 the same. 



560. Chipping Sparrow. Spizrlla xmvV///x. 



Range. North America east of the Plains, breeding from the Gulf to the 

 interior of Canada and Newfoundland.
