Range.— N(jrthern Hemisphere, breeding in the Arctic regions; south in win- 

 ter to New Jersey and Illinois. 



The Long-taileil Duck, as it is called, is 

 especially noticeable because the breeding 

 plumage of the male differs markedly 

 from that in the winter. In summer 

 their general plumage is blackish l)rown, 

 with a white patch around the eye, and 

 white belly. In winter they are largely 

 white. The central tail feathers are much 

 lengthened. They breed abundantly in 

 Greenland, Alaska and the Hudson Bay 

 Territory, placing their nests of grasses 

 and weeds on the ground near the water. 

 It is generally concealed in the long grass. 

 The eggs number from six to twelve.

 10, 1900. Nest on ground, lined with 

 down. Collector, S. H. Wallis.
