PERCHING BIRDS 



554. White-crowned Sparrow. Zonotri- 

 chia leucophrys leucophrys. 



Range. — North America breeding abundantly 

 in Labrador and about Hudson Bay, and casual- 

 ly 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 under- 

 pays are uniform grayish 

 white. These birds appear to 

 be nowhere as common as the White-throated 

 Sparrows with which they associate during mi- 

 grations 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 x .65. Data. Nachook, 

 Labrador, June 10, 1897. Nest of fine grasses on the ground in a clump of grass.
