pale tawny; outermost upper tail coverts white, streaked with brown; inner 

 tail feathers dull dark brown, lateral ones drab; outer surface of closed wing

 feathers of throat and breast thickly marked with brownish black shaft streaks 

 on whitish or buffy ground; rest of under surface abruptly white; sides with 

 a buffy tinge and dark shafts; flanks white, with narrow shaft stripes; feet 

 greenish. Total length 8.00-9.62 inches (203-242 mm.) (two specimens, from 

 Alaska and Florida). Males: folded wing 5.37-5.61 (136.5-142.5); bill along 

 culmeu 1.15-1.20 (29.1-30.5); tarsus 1.09-1.14 (27.8-29.0) (five specimens from 

 California, Alaska and British Columbia). Females: folded wing 4.79-5.05

 28.1) (nine specimens from California, Alaska and British Columbia). Adults, 

 ioth sexes, in fall and winter: "Similar to summer plumage, but the rusty tint 

 above almost or wholly absent, and the black markings less sharply defined" 

 (Baird, Brewer and Ridgway, 1884, I, p. 233). Juvenile plumage: Similar to 

 that of adults in summer but longer scapulars and other feathers of back 

 margined extensively with bright tawny and white; general buffy tone on 

 breast more intense. Natal plumage: Forehead and sides of head, buffy yellow; 

 chin and throat, white; stripes up middle of forehead, from bill to eye, from 

 bill to below eye, and from above eye to ear region, black; bill dusky, slightly 

 paler at base; top of head, back and wings, of mixed pattern, the down 

 feathers reddish brown at bases and black near ends and some with buffy 

 white tips; breast buff; belly chiefly white; legs and feet (dried) pale straw 

 yellow; nails blackish. 



Marks poe field identification — Medium small size (slightly smaller than 

 a Killdeer), short bill about as long as head, white chin, buffy foreneck and 

 breast finely streaked with dark brownish (this area constituting a broad, rather 

 abruptly outlined, pectoral band), and blackish rump and upper tail coverts. 

 More common on meadowland and less so on open flats than other sandpipers. 



Voice — A single, rather rasping tweet or TcreeTc ; in the breeding season a 

 deep, hollow, resonant, yet musical, too'-u, to6'-u, too'-u, too'-u (Nelson, 1887, 

 p. 108). 



Nest — In grass in dry situations though often in the vicinity of water; a 

 depression lined with a little grass. 



Eggs — -Usually 4, pointedly pear-shaped, measuring in inches, 1.42 to 1.58 

 by 1.02 to 1.11 (in millimeters, 36.1 to 40.2 by 25.9 to 28.2) ; ground-color drab, 

 with a greenish tinge in some specimens, spotted and blotched with umber 

 brown, variously distributed; deeper markings pale purplish gray (Murdoch, 

 1885, pp. Ill, 112). 



General msTEiBtrnoN — North and South America. Breeds commonly on 

 the Arctic coast of Alaska from the mouth of the Yukon to Point Barrow, 

 rarely in Mackenzie, aud probably on the Arctic coast northwest of Hudson 

 Bay. In migration occurs abundantly south to southern Alaska, and throughout 

 the United States east of the Eocky Mountains; in limited numbers on the 

 Pacific coast from British Columbia southward. Winters in central South 

 America in Chile, Bolivia and Argentina, up to 12,000 feet altitude (Cooke, 1910, 

 p. 35; et al.). 



DiSTEiBUTlON IN Calipobnia — Rather rare migrant coastwise; has been 

 recorded from: San Francisco Bay (Cooper, 1868, p. 8); Mill Valley Junction,
