Hab. Eastern Province of North America, breeding in the high north ; in winter, the whole 
of Middle America, South America, and the West Indies ; Falkland Islands ; occasional in 
Europe. 
Sp. Char. Adult in summer : Above, light brownish gray, much tinged, particularly on the 
crown, back, and inner scapulars, Avith light rusty buff or ochraceous, all the feathers black cen- 
trally, these markings largest and somewhat Y-shaped, or sagittate, on the scapulars, streak-like 
elsewhere, the streaks broadest on the crown and back ; rump dusky blackish, the feathers bor- 
dered with light gray ; upper tail-coverts pure Avhite, in marked contrast, some of the feathers 
having irregular sagittate, mostly concealed, spots of dusky. Tail brownish gray, the middle 
feathers blackish, and all slightly edged Avith whitish. Wing-coverts and tertials brownish gray, 
lighter on edges and dusky centrally, the shafts nearly black. Superciliary stripe and entire lower 
parts pure Avhite ; auriculars light buff, indistinctly streaked ; sides of head and neck, foreneck 
jugulum, and upper part of breast, streaked or dashed with dusky; sides and flanks Avith larger 
irregular markings of the same. Adult in winter : Wings, rump, upper tail-coverts, and tail as in 
summer plumage ; rest of upper parts continuous biwnish gray, relieved by rather indistinct 
mesial streaks of black; streaks on jugulum, etc., less sharply defined than in the summer plu- 
mage. Young, first plumage : Back and scapulars black, the feathers bordered terminally with pure 
white, and laterally with ferruginous, those of the middle of the back also tipped with this color ; 
feathers of the pileum and rump, as Avell as the tertials, also bordered with rusty ; Aving-coverts 
bordered with pale grayish buff. Otherwise as in the winter plumage, but breast, jugulum, etc., 
suffused with pale fulvous. 
Total length, about 7 inches ; Aving, 4.90 ; culmen, .90-1.00 ; tarsus, .95-1.00 ; middle toe, 
.70-. 75. 
Specimens from South America are exactly like northern ones, among Avhich there is the usual 
amount of individual variation. In midsummer the black of the back and scapulars increases in 
relative extent, partly by the wearing away of the rusty borders to the feathers, until, in some 
examples, the dorsal aspect is chiefly black.
