CATALOGUE OF CANADIAN BIRDS. 7 



Stercorarius parasiticus. 



PARASITIC JAEGER. 



This species was formerly called Richardson's Jaeger. It 

 summers in the Arctics, and during winter goes as far south as 

 Brazil and Chili, occurring as a regular visitant to the Bay of 

 Fundy in its migrations. 



Stercorarius longicaudus. 



LONG- TAILED JAEGER. 



This species is quite common in the Bay of Fundy during 

 its migrations, though reported as " rare " between that locality 

 and the Arctics. A few have been taken in Hudson's Bay. 



Gavia alba. 



IVORY GULL. 



An Arctic species that has been seldom seen in the temperate 

 latitudes of Canada. A few examples have straggled, accidentally, 

 to the Bay of Fundy and to Lake Ontario. 



Rissa tridactyla. 



KITTIWAKE. 



It is rather misleading to give the habitat of this species as 

 "Arctic regions," for, though KUMLIEN did find it abundant in 

 Cumberland Bay and at Disko, and Dr. BELL found it " especially 

 numerous at Cape Chudleigh," it has been found breeding in num- 

 bers on the islands of the Gulf of St. Lawrence by VERRILL, CORY, 

 and BREWSTER, and COMEAU reports its breeding near Point des 

 Monts ; while it is known to breed; also, along the Atlantic coast 

 of Nova Scotia and in the Bay of Fundy. 



It has been taken during winter in the vicinity of Montreal, 

 and in the Great Lakes.
