It is a rather remarkable fact that the Dunlin is the only species of _Tringa_ that nests in the British Islands. It breeds sparingly and locally in Cornwall, Devon, and Somerset, perhaps in Wales, and thence northwards, more generally, over the remainder of England, and in Scotland up to the Shetlands. Dunlins begin to move from the coasts in March and April, and to resort to their breeding places, which are situated on the marshy moorlands and mountain swamps, often at no great distance from the sea, or at least from tidal waters. The nest is a mere depression, often in a tussock of grass or rushes, or beneath a small bush, or even in a patch of thrift on bare sandy soil, lined with a few scraps of withered vegetation, or enclosed with a few twigs or roots. The four pyriform eggs are pale olive or pale brown, blotched and spotted with reddish- and blackish-brown and gray. We remark the same extraordinary difference between summer and winter plumage, as we have already observed in the Knot and some others. In summer or breeding plumage, the Dunlin is rich reddish-brown above, striped with dark brown; lower breast or gorget, deep black; remainder of under parts white. In winter the upper parts are chiefly ash-gray, and the under parts white, except the gorget, which is now grayish-brown. Outside the British Islands the Dunlin has a very wide distribution, breeding not only in the Arctic regions of both hemispheres, but in many temperate latitudes of the same; in winter it is dispersed over North Africa, Southern Asia, the Southern States of America, and the West Indies. At Heligoland, flocks of Dunlins invariably indicate bad weather. PURPLE SANDPIPER.
