Collier's New Encyclopedia (1921)
the Strepsilas, a small genus of birds of the plover family (Charadriidæ), intermediate between the true plovers and sandpipers. The common turnstone (S. interpres) appears in Great Britain as a winter migrant, but is not known to breed there; its breeding places being the shores of the Arctic Ocean in Europe, Asia, and America, though it breeds on the coasts of Scandinavia down to Denmark, laying four eggs of a greenish-gray color, spotted and streaked with bluish-ash and brown, in a shallow depression lined with a few dry leaves and bents. In winter the turnstone is found on the seashore all over the world, being probably the most cosmopolitan of all birds. It derives its name from its habit of turning over stones with its bill in search of its food, 1000 which consists of small crustaceans and mollusks. The common turnstone is nine inches in length, and is handsomely marked with black, white, and chestnut; the last-named color is reduced in autumn, when the plumage becomes duller; the legs and feet are orange. Another species, the black-headed turnstone (S. melanocephalus), breeds in Alaska and winters in California; and some place the surf-bird (Aphriza virgata) in this genus.
Aiton's Encyclopedia (1910)
a bird of the snipe kind. It is a shore bird. It gains its name from a habit of running along the shore of the sea turning stones over with its bill in search of insect food. Several distinct species are found along the seashore everywhere. Some of the local names are surfbird, calicoback, maggotsnipe, tanglepicker, chuckatuck, jinny, etc. The turnstone is closely allied to the plover and the sandpiper. See Snipe ; Sandpiper
