Casual. One specimen was observed through a glass by Mr.. 

 G. R. White, perched on a flag-staff at the rifle range at Ottawa 

 prior to 1881. (Ottawa Naturalist, Vol. V, p. 38.) Mr. Hay reports 

 one as having been seen at Port Sidney, Ont., on July 15th, 1897 r 

 it sailed several times about his place, and was distinctly seen. 

 I have also an old specimen taken many years ago in Ontario.

Circus kudsonius (Linn.) Vieill. 1807. 



Rare in Newfoundland. Only once seen at Cow head. {Reeks.} 

 Rather uncommon at Humber river, Newfoundland. (Louis H. 

 "Porter.) Audubon, saw it in Labrador. (Packard.) The following 

 are our most northern references to this bird : Spreadborough found 

 it abundant on both" sides of James bay in July and August, 1904; 

 Preble saw it at York Factory and Fort Churchill ; Dr. Robert Bell 

 records it from York Factory, Hudson bay; Clarke mentions its 

 occurrence at Fort Churchill, on the west side of the bay, and Rich- 

 ardson places its northern limit at Great Bear lake, in lat. 65°. 

 Bernard Ross, on the other hand, places its northern Umit at Great 

 Slave lake, and says that it is scarce there. 



It is a summer resident and generally distributed in Prince Edward 

 Island, Cape Breton Island, Nova Scotia, New Brunswick, Qi^ebec 

 and Ontario, and is very abundant throughout the whole prairie- 

 region, breeding as far north as Great Bear lake. 



Rare in the mountains, but not uncommon in the Columbia 

 valley from Revelstoke south. Rather common westward, and 

 becoming abundant at Sicamous and westward to Spence Bridge,.
