HARELDA GLACIALIS : LONG-TAILED DUCK. 319 



A common winter resident, arriving in October, and 

 remaining into April. " The Buffle-liead is not often 

 seen in the United States, except from fall to spring ; as 

 it usually retires to high latitudes to breed, as along the 

 Yukon and elsewhere in boreal America, its nidification 

 is consequently not generally known. A set of fourteen 

 eggs taken, the accompanying label states, from a 

 feathery nest in a dead poplar, some distance from the 

 ground, furnishes the following description : Shape, 

 perfectly ellipsoidal ; size, slightly over 2.00 inches in 

 length by 1.50 in breadth; color, a peculiar tint^ just 

 between rich creamy-white and grayish-olive, unvaried 

 by markings. Other eggs are described as being about 

 1.67 long by L25 broad, and buff-colored" (Coues, Birds 

 Northwest, 1874, p. 578).
