BIRDS OF THE VICINITY OF NEW YORK CITY 141 



Canvasback (Jyfhya z'allisncria). Occurs here as a not common migrant. 



American Scaup Duck ; Broad-bill ; Blue-bill ; Black-head ; Raft Duck 



(Aythya niariUi). The commonest Duck of our bays, where it is sometimes 

 seen in great numbers. It appears from the north about October i and remains 

 until its feeding grounds are frozen over, returning as soon as the ice breaks in 

 the early spring. 



Lesser Scaup Duck ; Little Blue-bill ; Creek Broadbill ; Raft Duck (Aythya 

 affiiiis). Not as comnidu as the preceding, with whicli its range in the main 

 agrees. 



Ring-necked Duck (Aythya cullaris). North America, breeding only in 

 the interior from Iowa northward. It is here a very rare, irregular transient 

 visitant. The last record is that of Braislin (Auk, XVI, 1899, p. 191) who 

 mentions a specimen from Great South Bay.

American Golden-eye; Whistler (Clanguhi claugula americana). In 

 favorable localities within our limits the Whistler is a not common migrant 

 and winter resident. 



Bufflehead ; Butterball (C/u; ;-//(*» t'/f(/ albcota). A not uncommon migrant 

 and winter resident. 



Old-squaw ; Old-wife ; South-southerly (Harclda hyeiitalis). A common 

 winter resident. 



Harlequin Duck (Histrioiiicus histrioiiicus) . Breeds from Newfoundland 

 northward, and winters southward to New Jersey. A very rare winter visi- 

 tant off our coast (Dutcher, Auk, III, 18.86, p. 434: VI, 1889, p. 134). 



The Labrador Duck (Cainf^tolaiiiius labradoriiis) , which formerly in- 

 habited the Atlantic Coast, breeding from Labrador northward and wintering 

 southward to New Jersey, is doubtless now extinct. The Labrador Duck was 

 apparently once a not uncommon winter bird on Long Island. In a paper by 

 William Dutcher (Auk, VIII, 1891, p. 201 ; see also Auk, XI, 1894, pp. 41. I75< 

 176.) summarizing our knowledge of its life-history and enumerating the extant 

 specimens, Mr. George N. Lawrence is quoted as saying: "I recollect that about
