Range.--Whole of North America, breeding in the Arctic regions, and wintering south of the United States, most abundant in the eastern parts of the United States during migrations. This species is blackish brown above, with light brown edgings to the feathers, and white below, except the chest, which is brownish, streaked with black. A very peculiar species, having the power, during the mating season, of inflating the throat to a great extent, making a balloon-like appendage, nearly the size of the bird. They have more the habits of Snipe, than do most of the Sandpipers, frequenting grassy meadows or marshes, in preference to the seashore. Their nests are grass lined depressions, and the eggs are grayish or greenish buff, blotched with brown. Size 1.45 × 1.00. Data.--Cape Smythe, Alaska, June 1900. Four eggs in a hollow in the ground, lined with grass. [Illustration 149: Sharp-tailed Sandpiper.

Range.--North America, breeding from Labrador and southern Greenland, northward and wintering from central to Southern South America; most common on the Atlantic coast. This species is 7.5 inches in length, and has white upper tail coverts; otherwise it is marked similarly to the preceding Sandpiper. Its nesting habits are the same as those of the majority of the family, and the three or four eggs that they lay cannot be distinguished from those of the following species. Size 1.30 × .90. These are one of the most common of the beach birds along the Atlantic coast during migrations; they are very often known as Bonaparte Sandpipers. 241. BAIRD'S SANDPIPER. _Pisobia bairdi_. Range.--North America, chiefly in the interior, breeding along the Arctic coast and about Hudson Bay, and wintering south of the United States. A very similar species to the preceding, but without the white rump. Their nests are hollows in the ground, generally concealed in a tuft of grass, and lined with grasses and a few leaves. They lay three or four eggs having a grayish colored ground, and marked with different shades of brown, and also with some faint markings of lilac. Size 1.30 × .90. Data.--Peel River, Arctic America, June 18, 1898. Four eggs, taken with the bird by an Indian. Eggs in a slight hollow on the river bank. 242. LEAST SANDPIPER. _Pisobia minutilla_. Range.--North America, breeding from the southern parts of the British Provinces northward; winters from southern United States southward. Common in the interior and on both coasts.
