WHITE-CROWNED SPARROW 



The summer home of the White-crowned Sparrow, in the eastern part of 

 its range, lies north of the United States, and these individuals winter in the 

 southern half of the eastern United States. The migratory movements of 

 these White-crowned Sparrows are fairly well shown in the accompanying 

 tables. But in the Rocky Mountain region and to the westward, this species 

 breaks up into several forms, one of which {leucophrys) breeds in the United 

 States south to New Mexico and central CaUfornia; another (gambeli) breeds, 

 for the most part, north of the United States; while, in the case of the third 

 (nuUalli), the summer and winter homes overlap for several hundred miles 

 from southern California to central Oregon. The data on hand indicate that 

 these forms migrate at widely differing dates, but there is not enough material 

 available to make detailed statement of these differences.
