I should be remiss if I did not take this opportunity of expressing 

 my appreciation to Mrs. D. D. Forsyth of Toronto, who so carefully and 

 painstakingly typed the entire manuscript of this work. 



Books and literature of various kinds were lent by the library of 

 McGill University, Montreal; the library of the Geological Survey of 

 Canada, at Ottawa; the Toronto Public Libraries; and the library of the 

 Royal Ontario Museum of Zoology at Toronto. 



Data on eggs and nesting were obtained mainly from Bent (1923, 

 1925). Colloquial names were selected mainly from McAtee (1923). 

 Data on food and feeding habits were condensed and adapted mainly 

 from McAtee (1911, 1918, 1922), from Mabbot (1920), and from Martin 

 and Uhler (1939). The maps showing the winter and breeding ranges 

 were prepared mainly from data furnished by the Fish and Wildlife 

 Service, U. S. Department of the Interior.
