74 GEOLOGICAL SURVEY OF CANADA. 
Common on the Missinabi and Moose rivers, breeding on both 
rivers. (Spreadborough.) Common in Muskoka and Parry Sound 
districts. Regular winter resident at Toronto, Ont. (/.H./leming.) 
A flock of young seen on the west coast of the Bruce peninsula in 
June, 1889, and old birds are often seen there in summer. (W. 
Saunders.) 
_ Breeds in the northern part of- Manitoba and northwesterly to 
the Barren Grounds. (Macfarlane.) Breeding at Jasper House, 
Alta., 1889; afew seen along streams in the Peace River district; 
noted at Elk river and Kettle river, B.C. and breeding at Osoyoos 
lake, B.C. (Spreadborough.) Though Nelson and Turner say that 
it is only a visitor in Alaska, Grinnell found an adult female in 
Prince William sound and Bishop a pair breeding on Lake Tagish 
and adults, usually in pairs, at several other places. Both Brooks 
and Fannin report it breeding in British Columbia and wintering 
abundantly on Okanagan lake. Found breeding at Canmore and 
Banff, Rocky Mountains, May, 1891. 
BrEeEpING Notes.—Mr. A. P. Low found it breeding on the 
shores of small lakes in Labrador; eggs were taken with the bird 
from under small spruces on the upper part of the Hamilton river, 
in the summer of 1896. 
Fairly common in Alberta, downy young killed June 24th, 1896, 
at the forks of Blindman river and the Red Deer. (D2fpze.) 
Breeding on the streams and larger lakes but absent from the 
smaller lakes that are devoid of fish in the Cariboo district, B.C. 
(Brooks.) 
This is a summer resident at Norway lake, Renfrew co., Ont., 
although I never obtained the nest; I have seen the bird, however, 
fly into a cavity in a pine tree about forty feet from the ground. 
I have learned that a pair breed every year in the bole of a decayed 
pine tree on an island in Bolis lake, Frontenac co., Ont. I have 
reason to believe that this species prefers, in Ontario, inland lakes 
bordered by woods and not large expanses of open water. (Kev. 
C.J. Young.) A pair of mergansers was breeding on a small rocky 
island in Lake Tagish at the entrance to Windy Arm. The nest 
was found by Osgood in a crevice in the cliffs about 15 feet above 
the water. It was made of down, and contained seveneggs. (Bzshop.)
