lo I Henshaw, Emperor Goose in Havjaii. l6c: 



hitherto unknown to occur in the islands, but when killed these 

 usually fell into the hands of natives and of sportsmen from whom 

 next to nothing can be learned respecting the contents of their 

 game bags save that among them were strange ducks. 



The capture of three " Black-headed Ducks" has been reported 

 from Puna and a photograph of two of these, taken after death 

 by Mr. H. E. Wilson, is before me as I write. From this I 

 identify them, with but little doubt, as the American Scaup Duck 

 {Ayt/iya tnarila nearcticd). Neither of the Scaups has hitherto 

 been reported from the group. 



A fine specimen of the Red-breasted Merganser (J/, serrator) 

 fell into the hands of Mr. C. M. Walton of Pahala, Kau, by whom 

 it was preserved. This is the second recorded instance of the 

 occurrence of this duck in the archipelago, though there is reason 

 to believe that its presence here is not so very exceptional. 



December g, a specimen of Larus g/aucescens, in superb juvenile 

 winter plumage, was shot near Hilo by Mr. John Rinehart. This 

 gull is known to occur in Hawaiian waters more often than any 

 other North American gull, being piloted down here from San 

 Francisco by both steamers and sailing vessels. 



But the most interesting capture to be recorded is that of four 

 Emperor Geese {Fhilacte canagica) at Kalapana, on the Puna 

 coast, December 12, by Mr. H. E. Wilson, who fortunately possessed 

 the interest and skill requisite to preserve all four. Two of the 

 birds I have seen. They are in superb winter plumage, and are 

 not only the first to be reported from the Hawaiian Islands but, if 

 I mistake not, from any locality anything like so far south as 

 latitude 19°. Several species of geese in small numbers have 

 found their way to the islands from time to time during the fall 

 migration, and during the present season small companies have 

 been reported here and there along the coast. No doubt it was in 

 company with other geese or with ducks that the present 

 wanderers were enticed to southern latitudes. 



Such casual occurrences as those above noted — but few in 

 comparison with the many that are never chronicled — indicate the 

 manner in which birds may be introduced to new and distant 

 lands, and how the habit of annual winter migration to suitable 

 regions is begun.
