Isle a la Crosse; flocking with crows on Buffalo lake. (/. M. 

 Macoun.) This well-known bird abounds in the Northwest 

 Territories and visits the remotest islands of the Arctic sea. 

 (Richardson.) North on the Mackenzie river to Arctic coast; 

 abundant. (Ross.) Abundant everywhere about Great Slave 

 lake. Once saw 28 together on the Barrens. (£. T.Seton.) This 

 species is abundant at Fort Anderson and on the lower Lockhart 

 and Anderson rivers ; and although not seen by us there it may 

 possibly breed on the shores of the Arctic sea. (Macfarlane.) 

 One specimen was seen at Indian Head, Sask., in May, 1892; others 

 were seen at Medicine Hat in the spring of 1 894 ; observed from the 

 mouth of Lesser Slave river to Island lake, Alta., in 1903; appar- 

 ently very rare in the Rocky mountains; only one seen at Banff in 

 the summer of 1891 ; only a pair seen at Revelstoke, on the Colum- 

 bia river, in May, 1890; a few were seen at Deer Park, Lower Arrow 

 lake, and others at Robson on the Columbia river, in June of that 

 year; observed at Trail, Sheep creek and Coryell, near the Inter- 

 national Boundary, B.C., in the summer of 1902; a pair was breed- 

 ing on a high cUfif about two miles from Elko, B.C., May, 1904; one 

 seen west of Midway, B.C., May i6th, 1905; saw three at Penticton, 

 B.C., April, 1903; occasionally seen near Chilli wack in the summer 

 of 1 901; very abundant on many parts of Vancouver island, but 

 chiefly at Comox and Nanaimo in June and July; they must breed 

 in the neighbourhood; a few also were seen at Barclay sound, on 

 the west coast of the island. (Spreadborough.) 



A resident throughout the province, chiefly northward and 

 coastwise; rarer than formerly. (Fannin.) Resident. (?) Not 

 common at Chilliwack. The ravens found on the summit of 

 the Coast range, descending to the valley in winter, are much larger 

 than the commoner simiatus, and have a different voice. I have 

 no doubt they belong to the larger sub-species. I shot a female 

 during the winter that was much larger than a male of the other 

 form; a common winter resident in the Cariboo district, B.C.; 

 tolerably common in winter at Lake Okanagan, B.C. (^Brooks.) 



Everywhere throughout the entire territory of Alaska including 

 the shores of the Arctic ocean and Behring sea and the various 

 islands of the latter, this bird is a well known resident. 

 {Nelson.) This species is a resident throughout the whole of
