78 NORTH AMEBICAK FAUNA. [No. 22, 



AUe alle (Linn.). Dovekie. 



This species is recorded as abundant in Baffin Bay, Davis 8trait, and 

 other parts of the Arctic seas, and it winters southward on the coast, 

 hence it probably occurs, at least in migrations, about the northern 

 part of Hudson Ba.j. 



Megalestris skua (Briinn.). Skua. 



JLunis keeasJi of Latham," stated to inhabit Hudson Bay, and based 

 on Hutchins's 'Esquimaux Keeask,''' probably refers to the present 

 species. Though it has apparentlj^ not since been recorded from 

 Hudson Bay, the facts of its presence in Hudson Straits and its 

 breeding at Lady Franklin Island, north of the straits, render its 

 occurrence on the waters of the Bay probable. 



Stercorarius pomarinus (Temm.). Pomarine Jaeger. 



Several seen near the mouth of Churchill River July 21. They 

 were pursuing the terns and small gulls with remarkable agility, 

 evidently to rob them of their prej'. A male was collected below 

 Cape Eskimo, where the birds were common August 3 to 8. They 

 were generally flying about over the tundra somewhat after the manner 

 of a marsh hawk, frequently hunting in small, noisj^ companies; but 

 sometimes several would be seen standing on a small knoll, apparently 

 asleep. Thej were easily decoyed by the imitation of the cry of a 

 bird in distress. Despite the frequency of melanism in this genus, I 

 saw no black jaegers of any species, though my Indian guide reported 

 seeing one at our camp '25 miles below Cape Eskimo. 



Richardson records the species from Igloolik, Melville Peninsula.'^ 



Stercorarius parasiticus (Linn.)., Parasitic Jaeger. 



First met with about 50 miles north of York Factor}', where several 

 were seen, and a female was shot Jul}' 19. The species was common 

 on the Barren Grounds below Cape Eskimo, August 4 to 13. In habits 

 it resembles ^S*. pomarinus. 



Clarke records a melanistic specimen from Fort Churchill.'* 



Stercorarius longicaudus Vieill. Long-tailed Jaeger. 



Edwards's plate of the 'Arctick Bird ' represents this species. In 

 his description he says the tail feathers are 13 inches long.*' Dr. Bell 

 records a specimen which was shot near York Factory bj' Dr. Matthews, 

 who presented it to him.-^ The catalogue of birds in the U. S. National 

 Museum collection records a specimen of S. I'/cIidrdsoin taken at Fort
