WHISTLING SWAN 
180. Olor columbianus, 54 in. 
Nostril situated at a greater distance from the eye 
than it is from the end of the bill; a small yellow spot 
on the bare space in front of the eye; plumage entirely 
white; bill and legs black. This is the swan that is 
found on the Atlantic coast, and is most abundant in 
the Miss. Valley. It is rare north of Chesapeake Bay, 
but it is abundant from there southward, in winter. 
They make a beautiful sight against the blue sky, their 7 
immense white wings slowly fanning the air and their 
long necks extended. 
Notes.—A peculiar, flageolet-like “Who, who, who.” 
(Elliott). 
Nest.—A mass of weeds, grass and feathers on the ! 
ground; 3 to 6 greenish buff eggs (4.00 x 2.75). 
Range.—Breeds within the Aretie Circle; winters 
south to the Gulf of Mexico; rare north of Va. on the 
Atlantic. 181. TRUMPETER SWAN (Olor bucinator) 
is larger (65 in.) and is found west of the Miss. It 
breeds from Ja., northwards. Nostril midway between ~ 
eye and tip of bill.
