The Eed-breasted iNIerganser aj)- 

 pears to be an inhabitant of the whole 

 of the more northerly portions of the 

 northern hemisphere. It is common 

 to North America, Europe, and Asia. In the latter country it is found as far to the 

 east as China and Japan. 



This is far more marine than the larger species, and is principally, but not wholly, 

 confined to the sea-coast, breeding as far south as latitude 45° north, and thence 

 northward to an uncertain extent, varying with the conditions and peculiarities of 

 the localities. It certainly breeds as far north as Alaska, on the Pacific, and Green- 

 land, on the Atlantic coasts, as well as in Iceland and in other extremely northern 

 latitudes. 



This bird is included by Mr. Swinhoe in the fauna of Formosa, and is also given 

 by him as having been found at Amoy, China. Temminck mentions it as occurring 

 in Japan. It is given by Mr. T. L. Powys as not uncommon in winter in Epirus, 

 Albania, and Corfu ; and Mr. C. A. Wright ('' Ibis," 1864) speaks of this as being a 

 common species at Malta — as much rarer, however, in some years than in others. 

 It arrives there in November, but is present in much larger numbers in December and 

 January, immature birds being more abundant than adults. It is also said by Mr. H. 

 Saunders to occur in Southern Spain in winter, especially on Lake Albufera. 



It was met with on Nova Zembla by Von Heuglin ; and was found, mingled with 



Pidlus.
