However, recent field work in the Carolinas, especially South 

 Carolina, has shown that oblitus occurs as a regular winterer in old 

 fields on the piedmont and coastal plain (Johnston, 1956; Quay, 1957; 

 Norris and Hight, 1957). Norris (1960), in analyzing the racial 

 types of a sample of over 1700 wintering Savannah sparrows in the 

 Savannah River Plant in South Carolina, found that more than 15

This race is the smallest of the Savannah sparrows and has a
