most immune to stress of wind and water, though making its 

 home on the ocean Hke the others. Comparatively few come 

 ashore in storms. It is beheved from the evidence furnished 

 by Okl-squaw gunners, who float their decoys sometimes 

 several miles from the beach out in the ocean, that they are 

 nearly as common as the " Sea Crow'' {Alca torda). 



12. Megalestris skua. Skua Gull. 



Casual. The only specimen from Long Island has been re- 

 corded by Mr. Dutcher (Auk, iii, 1886, p. 432). This bird 

 was found in drift ice, back of the beach' at Amagansett, on 

 March 17, 1886, by a member of the life-saving crew, and 

 may have been there for a considerable period. 



13. Stercorarius pomarinus. Pomarine Jaeger. 



A less common species than the Parasitic Jaeger, it neverthe- 

 less seems to be a reo^ular migrant from xVugust to November 

 passing usually at a distance from the coast. It migrates 

 southward from July to late October (Chapman, Guide "to 

 Local Collection of Birds, p. 15). Mr. B. H. Dutcher found both 

 species common at Little Gull Island, Aug. 6 to 16, 1888, where 

 they resorted in pursuit of blue-fish, and until fired at several 

 times, were very famihar. They were likewise abundant from 

 late in September until the beginning 'of November off the 

 coast of Massachusetts in the same year, attracted by good 

 fishing grounds. 



14. Stercorarius parasiticus. Parasitic Jaeger. 

 Apparently more common than the preceding species and 



similar in habits. April 30 (Rockaway) ; Aug. 6 (Gull Island, 

 B. H. Dutcher, Auk, vi, pp. 125) to Nov. 9 (Amityville). 



15. Stercorarius longicaudus. Long-tailed Jaeger. 

 Very rare or casual off the Long Island coast. 



It has long been the custom to include this species in State 

 and other local lists, probably properly so, though there is
