INTRODUCED BREEDER. 
SUBFAMILY CYGNIN/E.—SWANS. 
GENUs OLorR. 
[180]. Olor columbianus (Ord.). Whistling Swan. 
[ Wild Swan]. 
Raner.—North America. Breeds from northern 
Alaska south to Becharof Lake, Alaska Peninsula, and on 
Arctic islands from about latitude 74° south to northern 
Mackenzie and northwestern Hudson Bay; in migration 
oceurs west to Behring Island; winters on the Pacific 
Coast from southern British Columbia, rarely south to 
southern California, and in the interior from Lake Erie 
and southern Illinois to coasts of Louisiana and Texas, and 
on Atlantic Coast from Delaware and Maryland to South 
Carolina, rarely north to Massachusetts and south to 
Florida; casual in northern Mexico; accidental in Scot- 
land and Bermuda.
