Elanotdes forficatus (LINN.) COUES. 1875. 
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; 
it sailed several times about his place, and was distinctly seen. 
I have also an old specimen taken many years ago in Ontario. 
(J. H. Fleming.) Only one individual has been seen at Aweme, 
Man., in 23 years. (Criddle.)

Circus hudsonius (LINN.) VIEILL. 1807. 
Rare in Newfoundland. Only once seen at Cow head. (Reeks.) 
Rather uncommon at Humber river, Newfoundland. (Lows 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 limit 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, Quebec 
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,
