Isle a la Crosse; flocking with crows on Buffalo lake. (J. 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. (oss.) Abundant everywhere about Great Slave 
lake. Once saw 28 together on the Barrens. (E. 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 1894; 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 cliff about two miles from Elko, B.C., May, 1904; one 
seen west of Midway, B.C., May 16th, 1905; saw three at Penticton, 
B.C., April, 1903; occasionally seen near Chilliwack in the summer 
of 1901; 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 sinuatus, 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
