This bird inhabits both the old and new continents, being known in 
England by the name of the Dunlin ; and in the United States, along 
the shores of New Jersey, by that of the Red-back. Its residence here 
is but transient, chiefly in April and May, while passing to the arctic 
regions to breed ; and in September and October, when on its return 
southward to winter quarters. During their stay they seldom collect 
in separate flocks by themselves ; but mix with various other species of 
strand-birds, among whom they are rendered conspicuous by the red 
color of the upper • part of their plumage. They frequent the muddy 
flats, and shores of the salt marshes, at low water, feeding on small 
worms and other insects which generally abound in such places. In 
the month of May they are extremely fat. 
This bird is said to inhabit Greenland, Iceland, Scandinavia, the Alps 
of Siberia ; and in its migrations the coasts of the Caspian Sca.f It 
has not, till now, been recognised by naturalists as inhabiting this part 
of North America. Wherever its breeding place may be, it probably 
begins to lay at a late period of the season, as in numbers of females 
which I examined on the first of June, the eggs were no larger than 
grains of mustard seed. 
Length of the Red-back eight inches and a half, extent fifteen inches ; 
bill black, longer than the head (which would seem to rank it with the 
Snipes), slightly bent, grooved on the upper mandible, and wrinkled at 
the base ; crown, back and scapulars, bright reddish rust, spotted with 
black ; wing-coverts pale olive ; quills darker ; the first tipped, the 
latter crossed, with white ; front, cheeks, hind-head, and sides of the 
neck, quite round, also the breast, grayish white, marked with small 
specks of black ; belly white, marked with a broad crescent of black ; 
tail pale olive, the two middle feathers centered with black ; legs and feet
