DIVERS—COLD-WEATHER DIVERS. 41 
Lake of the Woods, thence to Leech, Cass and Red 
lakes, etc.; also from Lake Winnipeg down the Great 
Red River of the North; rare south of Southern Min- 
nesota. 
They associate with the harlequin duck among the 
rapids; and are like G. clangula, expert divers; al- 
most impossible to catch when wounded. 
They nest, like clangula, in holes and rocky places, 
and their general habits appear the same. Length 
22.00; wing 9.50; tarsus 1.60; extent 31.00; middle toe 
2.50. 
GENUS Histrionicus. 
Histrionicus histrionicus—HARLEQUIN DUCK.—Hab- 
itat—British North America, coastwise ; rare in the in- 
terior, except in the Rocky and Sierra Nevada moun- 
tains, where rapids abound. 
This little duck, named from its fantastic and clown- 
like habits and coloration, is of irregular distribution; 
chiefly found in the interior, in the whirl of the rapids 
as much as the eddies; no water appears too rough or 
too rapid for it, and it seems to live more under water 
than upon the top. It comes south as far as Rainy 
River, hanging around the rapids near the lake; but 
few are seen together, generally one. They nest like 
G. clangula preferring isolated places. 
Little is known of this duck in the interior, owing 
to its retired habits in almost inaccessible places. 
Length 17.00; wing 7.50; tarsus 1.50; extent 26.00; 
middle toe 2.00.
