membrane extends beyond the second. There is a tendency to 

 hexagonal subdivision in the bare portion of tibiae anteriorly. 

 The tail is doubly emaTginate. 



Two species are known, the common Semipalmated Sand- 

 piper or ''Peep," and a northwestern relative.

HAB. The whole of North and Middle, and a considerable portion of South America; 

 throughout the West Indies, Bermuda; south to Colombia and Brazil; breeding chiefly, if 

 not exclusively, north of the United States. 



SP. CHAE. Adult, breeding plumage: Upper surface light grayish brown, the sidesofthe 

 pileum and edges of some of the scapulars and interscapulars tinged with pale buffy cinna- 

 mon, but this sometimes almost wholly absent; pileum heavily streaked, and dorsal region 

 heavily spotted with black, the latter color occupying the central portion of each feather. 

 A streaked white superciliary stripe, and dusky loral space, the latter usually very dis- 

 tinctly denned along its upper edge, the lower part broken into streaks, which extend back- 

 ward across the cheeks ; auriculars streaked grayish brown. Lower parts pure white, the 

 jugulum and breast tinged with ashy and streaked with dusky. Winter plumage: Above 

 brownish gray, relieved by dusky shaft- streaks; superciliary stripe and lower parts pure 

 white, the jugulum faintly streaked. Young: Similar to the summer adult, but jugulum 

 tinged with pale grayish buff, and without well-defined streaks or spots, the scapulars and 

 interscapulars bordered terminally with white, and the brown usually less rusty. Downy 

 young: Forehead dingy white, divided by a mesial line of black; crown light chestnut, 

 marbled posteriorly with black and white; occiput mottled whitish. A distinct loral line of 

 black, forking just before the eye, the upper branch running toward the anterior corner of 

 the eye, the other inclining downward. Throat fulvous-white; other lower parts whitish, 

 nearly pure on the abdomen. Upper parts pale fulvous-brown laterally, black centrally, 

 the whole surface thickly bespangled with fine white tufts, terminating the down- filaments. 



Wing, 3,50-4.00(3.88); culmen, .6S-.92 (.77); tarsus, .80-. 95 (.86); middle tee, .55-.65 (.61). 

 [Eighteen summer adults measured.] 



This is perhaps the most abundant of the Sandpipers during 

 the migrations, when several hundred may sometimes be seen 

 in a single flock. Its habits are so much like those of other 

 species that no special description is required.
