126 GEOLOGICAL SURVEY OF CANADA. 
April, 1892. Seen passing over Revelstoke, B.C., from 18th to 20th 
April, 1890. This is the most common swan in the interior of the 
North West Territories. It breeds as far south as Lat. 61°, but 
principally within the Arctic circle and in its migrations generally 
precedes the geese by a few days. (Azchardson.) North to the 
Arctic circle, on the Mackenzie River, breeds along the river. 
(Ross.) Very rare in Alaska, but is not uncommon in northern 
British Columbia, according to Fannin. 
BrEEDING Nores.—Several nests of this species were met with in 
the Barren Grounds, on islands in Franklin Bay, and on the beach 
one was taken which contained six eggs. It was composed of a 
quantity of hay, down and feathers intermixed, and this was the 
general mode of structure of the nests of both swans. (Mac- 
farlane.) A pair remained at Sumas Lake, B.C. throughout the 
summer of 1891 and swans (apparently this species) winter on 
Lake Okanagan, B. C. (Svooks.) It occasionally breeds in 
Assiniboia, although its natural breeding-grounds are much 
further north. A pair was found breeding at Buffalo Lake, Alberta, 
on April 7th, 1891. The nest contained five eggs. Mr. Spaulding 
described the nest as being a large structure, three feet in diameter, 
composed of sods, grass and rushes and lined with feathers and 
down. Mr. Sanderson who has lived all his life in Assiniboia and 
Saskatchewan informs me that wild swans used to breed on some 
of the lakes in Northern Assiniboia and Saskatchewan before the 
Canadian Pacific Railway was built. The last nest he found was 
during the spring of 1885, during the Northwest rebellion. It 
was at Sounding Lake in Assiniboia, and contained four fresh 
eggs (Ratne.)
