SONG SPARROW 



This species, as a whole, ranges from ocean lo ocean, hut over much of ihis 

 wide area it is not possihle to trace the movements of the migrating individuals 

 because the observers cannot distinguish these from the resident breeding birds. 

 Thus, on the Pacific slope most of the Song Sparrows perform a more or less 

 extended migration, but some winter north to British Columbia and others breed 

 south to Lower California. It is not possible, therefore, to give any migrating dates 

 for the Pacific slope. In the eastern United States the birds winter north regu- 

 larly to Nebraska and New Jersey, and breed south to southern Nebraska and 

 southern Virginia. Thus there is a belt in the vicinity of the parallel of 40° N. lati- 

 tude in which Song Sparrows are found every month in the year and no migration 

 data are available.
