280 DUCK. 



wing a white band ; legs red ; claws black. One, supposed to be a 

 young bird, had the tips of the greater wing coverts white, the 

 secondaries white above, and below ; next series, under the wing, 

 white, with the shafts, and a small part of the webs, dusky ; back 

 and scapulars edged with light brown ; the webs and claws black. 

 The female is brown where the male is black, and the protuberance 

 at the base of the bill wanting. 



This species is now and then seen on the coasts of England in 

 the winter ; more frequently in Denmark and Russia ; in some parts 

 of Siberia very common, and known also at Kamtschatka ; but 

 probably neither this nor the last are fouud in Greenland, as the 

 names do not occur in the Fauna. In breeding time goes far 

 inland to lay the eggs, which are eight or ten in number, and white. 

 After the breeding season the males are said to depart, the females 

 staying behind, till the young are able to fly, when the two last go 

 likewise away, though to what part is not certain. It appears to be the 

 bird called at Kamtschatka, Turpan ; though this is in greater plenty 

 at Ochotska, especially about the Equinox, when fifty or more of the 

 natives, in boats, surround the whole flock, driving them in the flood, 

 up that river ; as soon as it ebbs, the whole company fall upon 

 them at once with clubs, and often kill so many, that each man has 

 twenty or thirty for his share. 



Inhabits also North America in the summer, and breeds about 

 Hudson's Bay ; the nest composed of grass, the eggs from four 

 to six ; hatches in July ; feeds on grass ; called there Cuscusi qua 

 turn. It retires south in winter, at which season is frequently seen 

 as far as New York ; has been met with also at Aoonalashka : re- 

 turns to Sweden the latest of any, and stays the longest ; even the 

 eggs have been found fresh laid the beginning of July, they are 

 generally deposited under the juniper bushes, with a covering of 

 elastic feathers ; they live entirely on shells. 



The windpipe of this bird is of a curious construction ; just below 

 the larynx is a bony cavity, of almost one inch long ; from this the
