LAMELLI ROSTRAL SWIMMERS 
155. Harlequin Duck. Histrionicus 
histrionicus. 
Range. — Northern Hemisphere in America, 
breeding from Newfoundland and the Rocky 
Mountains in Colorado, northward. South in win- 
ter to California and New England. 
A beautiful and most gorgeous bird, not in col- 
ors, but in the oddity of the markings, the colors 
only including black, white, gray and chestnut. 
Either sex can be recognized by the small short 
Greenish buff 
bill. They breed mostly in single pairs along 
swiftly running streams, placing their nest, which 
is woven of weeds and grasses, in the ground 
near the water. It is also claimed that they some- 
times nest in hollow trees. They lay from five 
to eight eggs, yellowish or greenish buff in color. 
Size 2.30 x 1.60. Data. — Peel River, Alaska, June 
13, 1898. Seven eggs in a hollow in river bank, 
lined with down. Collector, C. E. Whittaker. 
Harlequin Duck 
Labrador Duck 
156. Labrador Duck. Camptorhynchus labra- 
dorius. 
This bird, whose range was from Labrador to New Jersey in the winter, 
has probably been extinct since 1875, when the last authentic capture was 
made. It is a strange fact that a bird of this character should have been 
completely exterminated, even though they were often sold in the markets. 
Only forty-one specimens are known to be preserved at present and nothing 
is known in regard to their nesting habits or eggs.
