18 CHECK LIST OF THE 



(150) Ring=necked Duck. 



(Aythya collaris.) 

 Less abundant than the last, with which it is generally confused. 

 It probably breeds throughout its range, for I have often seen it here 

 in summer, though I never found its nest. In eastern Manitoba it breeds 

 regularly. 



Genus CLANGULA. 



(151) American Golden=eye. (Whistler.) 



(Clangula clangula americana.) 



Common winter visitor and probably breeds in the northern part of 

 the Province, as it regularly does so in all the wooded parts of southern 

 Manitoba. 



The bulk arrive in southern Ontario about the end of October -md 

 remain until the ice breaks up in the spring. 



(*) (152) Barrow's Golden-eye. 

 (Clangula islandica.) 

 An occasional visitor in winter. 



Genus CHARITONETTA. 



(153) Buflfle-head. 



(Charitonetta albeola.) 



Common spring and autumn visitor throughout the Province, breed- 

 ing at some points in southern Ontario, and probably doing so regularly 

 in the more northern portions. 



They arrive as soon as the ice goes out in spring and remain in the 

 autumn until their haunts are frozen over. 



Genus HARELDA. 



(154) Long-tailed Duck. (Coween.) 



(Harelda hyemalis.) 



A very abundant winter resident on the lakes, arriving about the 

 beginning of November and departing at the end of April. Breeds along 

 the Arctic coast. 



Genus HISTRIONICUS. 



(155) Harlequin Duck. 



(Histrionicus histrionicus.) 



A very rare visitor.
