LONG-TAILED J/EGER. Stercorarius longkaudus Vieillot. 



Range. — Arctic regions of both hemispheres; south in winter to 

 Gibraltar and Japan. 



Breeding range. — Since the long-tailed jaeger seems to be confined 

 in winter to the Eastern Hemisphere and finds its principal summer 

 home on the Arctic islands north of Europe and Asia, it is natural 

 that it should be most common during the latter season in those parts 

 of the Western Hemisphere which are nearest these mam breeding 

 grounds. It is an abundant breeder in northern Greenland on both 

 coasts south to Scoresby Sound on the east and Disco Bay on the 

 west; it is equally common on the neighboring Ellesmere Island from 

 Cape Union on the north (Feilden) to King Oscar Land on the south- 

 west (Sverdrup). On the western side of North America it ranges 

 east from Siberia, breeding in Kotzebue and Norton Sounds, south to 

 St. Michael (Nelson) and east along the Arctic coast to Franklin Bay 

 (MacFarlane) . It nested inland on the tundra near Fort Anderson, 

 and eggs were sent to the United States National Museum, claimed to 

 have been taken as far inland as La Pierre House, Yukon, and are in 

 the Thayer Museum from the Caribou Hills, Mackenzie. Between 

 these two breeding areas in North America lies a district stretching 

 across 35 degrees of longitude, in which the species is not yet known to 

 occur during summer. 



Winter range. — It seems probable that the long-tailed jaeger does 

 not regularly winter anywhere in the Western Hemisphere. There 

 are only two records during the winter season (from November to 

 May) , and if not mistakes in identification they must represent acci- 

 dental occurrences. The winter home is in the Eastern Hemisphere, 

 south to Gibraltar on the Atlantic side and to Japan on the Pacific. 



Spring migration. — The first birds of this species arrived at St. 

 Michael, Alaska, May 16, 1881 (Nelson); Nulato, Alaska, May 15, 

 1868 (specimen in U. S. National Museum); Kowak River, Alaska, 

 May 22, 1899 (Grinnell); and at Point Barrow, Alaska, May 30, 18S3
