It is rather a remarkable fact that this species, the _Strepsilas interpres_ of naturalists, does not breed in the British Islands. Some naturalists have suspected that it does so on the Hebrides, and it has been said to nest on the Channel Islands, but no direct proof has yet been obtained. Under exceptional circumstances the Turnstone may be met with inland, especially during the season of its migrations, but otherwise it is strictly a coast-bird, as much so as the Oyster-catcher, and rears its young upon the shore. This somewhat singular bird is met with on the British coasts, most commonly during its passage north or south, comparatively few individuals remaining upon them for the winter. The Turnstone cannot readily be confused with any other coast bird, its mottled black and chestnut upper parts, black throat and breast, and white belly, being very distinctive. The wings and tail during flight exhibit a good deal of white upon them. Turnstones, chiefly young birds, begin to arrive on the British coasts at the end of July, and the migration of the species continues through August and September; the return passage in spring may be remarked towards the end of April, and lasts for about a month. Mud-flats, slob-lands, and salt-marshes are not frequented much by the Turnstone; it always prefers the low rocky coasts, and seems specially fond of haunting rocks and islands. Social to a great extent in summer, in winter this bird is more or less gregarious; but many odd individuals attach themselves to parties of other shore-frequenting species. An example now lying before me was shot from the company of Common Sandpipers. The Turnstone is a restless little creature, ever on the run in quest of food. It may be watched hunting about the beaches, or running amongst pebbles, and over the piles of drifted rubbish that the tide washes up in a long irregular line along the shore. In watching the actions of this bird, the observer cannot fail to remark its singular habit of turning over shells and other objects, in quest of the small marine creatures that lurk under them, with its conical shaped beak, and perhaps occasionally with its breast as well. This peculiarity has gained for the Turnstone its trivial name. Not only does it run about the sand and rocks, but it frequently wades, and has even been seen to swim just outside the line of breakers, rising from time to time, flying a little way and then settling upon the water again. The flight of this bird is not very rapid, and generally taken close to the ground; its note is a shrill whistle, resembling the syllable _keet_. During the love season this note is run into a rapid trill. The food of the Turnstone is composed of sand-worms, crustaceans, molluscs, and other small marine animals.
