Marks tor field iDENTiriCATiON — Small size, needle-like bill (fig. 58), 

 slender head and neck, white under surface, and, in summer plumage, absence 

 of conspicuous streaking or barring on back of head and back, and reddish 

 sides of neck. Frequents open water, either salt or fresh; swims gracefully 

 and with quick movements. Among Phalaropes, distinguished by smaller size, 

 short, slender bill, dark rump, and in summer plumage by blackish head and 

 back. The phalarope most commonly met with on inland waters. 



Voice — A plaintive "pe-et, pe-et, " or "pleep, pleep, " or "wit, wit." As 

 the birds take wing from the water, these notes may be uttered at intervals 

 of one or two seconds. 



Nest — On banks of sloughs or near shores of small lakes; a depression 

 molded in grassy sod and situated on top of a small hummock; sometimes a 

 small collection of marsh grass, but arranged with little care. 



Eggs — 3 to 4, pear-shaped, measuring in inches, 1.10 to 1.30 by 0.75 to 0.85 

 (in millimeters, 28.0 to 33.0 by 19.1 to 21.6), and averaging 1.20 by 0.82 (30.5 

 by 20.8) ; ground color greenish-olive, light or dark buffy, or even grayish olive, 

 with either large or small markings of dark brown, sometimes aggregated 

 around larger end to form a dark zone, or else rather evenly distributed over 

 the whole egg (authors). Slightly smaller and less coarsely or deeply marked 

 than those of the Eed Phalarope. 



General distribution — ^Both hemispheres. In North America breeds from 

 northern Alaska, Melville Island and central Greenland, south to the Aleutian 

 Islands, valley of the upper Yukon, northern Mackenzie, central Keewatin,
