PARASITIC JAEGER. Stercorarius parasiticus (LiNNiEus). 
Range. — Both hemispheres, from the Arctic islands south to Aus- 
tralia, southern Africa, and Brazil. 
Breeding range. — The parasitic jaeger breeds on many of the Arctic 
islands of the Eastern Hemisphere and south to Scotland, and from 
Point Barrow, Banks Land (Bay of Mercy), Melville Island (Winter 
Harbor), and Godhavn, Greenland, south to Kamchatka, (Bering 
Island) Near Islands (Agattu), Aleutians (Kiska and Amchitka), 
Kodiak Island, and Glacier Bay, Alaska, Great Slave Lake (Stone 
Island and the eastern end of the lake), to near York Factory, 
Keewatin, and to Hudson Strait. 
Winter range.— Winter records for the parasitic jaeger in the Western 
Hemisphere are so rare as to suggest the probability that the species 
does not regularly occur at that season along the coasts of either North 
or South America. It was taken both December 4 and June 20 at 
Rio Janeiro, Brazil (Saunders), but of course the June bird was an 
accidental straggler, unless this is really a mistake in labeling for 
January. A summer bird also was taken on Barbados July 10, 
1888 (Feilden). These three seem to be the only certain records at 
any season of the year for South America and the West Indies, and 
there seems to be no record at any time of the year for Central 
America and Mexico. There are several December records for the 
United States, but these seem to represent late fall migrants rather 
than wintering birds. In the Eastern Hemisphere the species winters
