NOMENCLATURE OF BIRDS 



same race. The Black Duck is currently considered to be merely a race of Anas 

 fulvigula (Delacour and Mayr, 1945; Scott, 1951). The Black Duck travels in 

 winter as far south as the winter quarters of both the Mottled Duck and the 

 Florida Duck, evidence, perhaps, that the isolating mechanism by which the 

 races of fulvigula remain distinct may not be so simple as set forth in the text. 

 But it does hold that most of the Black Duck population winters north of these 

 sedentary relatives.
