[Illustration: FIG. 96.--STONE-CURLEW. ⅐ natural size.] Beak black, yellowish at the base; irides, orbits, legs, and feet yellow; upper parts mottled pale brown; wing-coverts with white tips, forming two narrow bars; quill black; throat and stripe beneath the eye white; neck and breast buff streaked with dark brown. Length, seventeen inches. Sexes alike. * * * * * The stone-curlew owes its name to a superficial resemblance in its size and pale brown, mottled plumage to the common curlew, and to its preference for a sandy or stony soil. It is also called the thick-knee, from the curious conformation of its knees, which are very massive, and have a somewhat bulbous appearance. Its other common names are big plover and Norfolk plover, Norfolk and Suffolk being now the headquarters of this species in England, although it is still found in small and, sad to say, diminishing numbers in suitable localities from Hampshire and Dorsetshire in the south to the wolds of Lincolnshire and the East Riding of Yorkshire in the north. It does not occur in Ireland. It is a bird of a somewhat singular appearance, and is the sole representative of its family in Europe. It is a summer visitor to England, a few birds remaining to winter in the southern counties, and inhabits extensive heaths where there are patches of stony or pebbly ground; and it also frequents fallows and downs. In its habits it is semi-nocturnal, feeding principally by night; it is by night that its wild, clear, ringing cry is usually heard. Its breeding-time is about the middle of April, when it deposits its two eggs in a slight hollow in the ground, among the flint pebbles and scanty vegetation. The eggs are buff-coloured, spotted and streaked with grey and brown, and are very hard to discover, so well do they harmonise in hue and markings with the sandy and pebbly ground on which they are placed.
