1891. (Winge.) Breeds in large numbers on Nottingham Island 
in Hudson Strait ; and at Churchill and York Factory, Hudson 
Bay. (Dr. R. Bell.) A rare summer migrant in Nova Scotia. Once 
captured a brood of young ones on Grand Lake. (Dowyus.) In 
New Brunswick, Quebec and Ontario, this is only a migrant, and 
I strongly suspect that some of the breeding stations mentioned 
above are those of the Greater Scaup, which is certainly a more 
eastern bird than this species. It is one of the commonest ducks 
in the prairie region and northward to the very edge of the Bar- 
ren Grounds. It breeds in all the ponds and by the little lakes 
from Lat. 49° to the Arctic Circle and beyond. Nelson says this 
is a very rare straggler in Alaska. Fannin and Brooks report it 
tolerably common in British Columbia. The latter says it winters 
on Lake Okanagan, B.C. 
BREEDING Notes.—This species was first seen at Deep Lake, 
Indian Head, Assa., on April 16th, 1892, at which time eight indi- 
viduals were observed ; they very shortly after came in great 
numbers, and a pair shot had their stomachs full of water-insects, 
which are very abundant in the lake. On June 23rd found a nest 
containing nine eggs. The nest was in the middle of a “ slough” 
in a mass of last year’s rushes (Scevpus lacustris), lined with down 
from the bird’s own breast. (Spreadborough.) Three sets of eggs 
taken at Burnt Lake, Alberta, June 14th and 15th, 1896; breeds 
also in Manitoba, but nowhere common. (Lizffie.) 
More numerous than the preceding species, breeding through- 
out northwestern Canada. In Assiniboia it usually nests on the 
small islands in the lakes. On June 15th, 1893, I found three 
nests on a small island where a colony of Avocets was nesting. 
The nests were built on the grass in hollows, lined with down. 
The eggs, like the preceding species, are dark drab, but of course 
much smaller in size. (Razne.) 
Over a dozen nests of this species were secured. They were 
usually found in the midst of aswamp,a mere hole or depression 
in the centre of a tuft of turf or tussock of grass, lined with more 
or less down, feathers and hay. Nine was the general number of 
eggs ina nest, though a few contained not more than six or seven. 
(Macfarlane.) 
On the 29th June, 1895, this species was found breeding in com- 
pany with the Pintail and Gadwell on an island in Cypress Lake,
