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 

 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 (4.00x2.75). 



Range. Breeds within the Arctic 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 la., northwards. Nostril midway between 

 eye and tip of bill.
