126 GEOLOGICAL SURVEY OF CANADA. 



April, 1892. Seen passing over Revelstoke, B.C., from i8th 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. (^Richardson.) 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 Notes. — Several nests of this species were met with in 

 the Barren Gruunds, 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. (Brooks^ 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 (Raine.)
