This is the smallest of our Sandpipers, being under six inches in length. Except for size, they are similar in appearance to Baird's Sandpiper, only the back is browner. A very abundant species during migrations, being found on the seashore or in marshes, nearly always in company with other species of the family. Their nests are the same as other Sandpipers, and the eggs are grayish, thickly specked with brown. Size 1.15 × .80. Data.--Peel River, Arctic America, June 20, 1899. Nest simply a depression in the river bank, lined with grass. [Illustration 150: White-rumped Sandpiper. Baird's Sandpiper. Least Sandpiper.] [Illustration: Grayish.] [Illustration: left hand margin.] Page 149 242.1. LONG-TOED STINT. _Pisobia damacensis_. An Asiatic species accidentally found on the Alaskan shores. It is a very similar bird to the Least Sandpiper, and about the same size. As implied by its name, it has unusually long toes. 243. DUNLIN. _Pelidna alpina alpina_. A very common Sandpiper in the British Isles and in Europe, but only casually occurring as a straggler along the Atlantic coast. Very similar to the next species, but a trifle smaller. The nest and eggs do not differ from the following. 243a. RED-BACKED SANDPIPER. _Pelidna alpina sakhalina_. Range.--Whole of North America, breeding from southern Greenland, Labrador, Hudson Bay and the Yukon, northward, wintering from the Gulf States southward. This handsome species is similar to the Pribilof Sandpiper, but is smaller (length 8 inches), the upperparts are more reddish, the breast more heavily streaked, and it has a black patch on the belly instead of on the breast as in ptilocnemis. Their nesting habits are similar to others of the family; they lay three or four eggs with a brownish or greenish buff color, heavily blotched and spotted with shades of brown and chestnut. Size 1.40 × 1.00. Data.--- Peel River, Arctic America, June 30, 1899. Nest a simple cavity in the ground, lined with a few grasses and three or four leaves. Collector, J. O. Stringer. 244. CURLEW SANDPIPER. _Erolia ferruginea_. Range.--A common Old World species, but regarded as rare in eastern North America and northern Alaska. A bird of slighter build, but similar coloration to the Knot; smaller (length eight inches) and with a slightly decurved bill. Until within recent years, eggs of these birds were rarely seen in collections, and I believe they have not yet been taken in this country, although a few pairs nest along our Arctic coast. Their eggs are very similar to those of the Red-backed Sandpiper, but average somewhat larger. Size 1.50 × 1.05. Data.--Kola, northern Lapland, June 15, 1898. Four eggs laid in a grass-lined hollow in the ground. Collector, J. Ramberg. [Illustration 151: Greenish buff.] [Illustration: Red-backed Sandpiper.
