Its breeding range is in Arctic America, whence it migrates to the tropics of America for the winter, and presumably those examples that visit us have come _via_ Greenland, Iceland, and the Faroes. The upper parts are brown, with lighter margins to the feathers; chin and throat whitish; breast buff, streaked with brown. Length 8 in.; bill 1·1 in.; wing 5·3 in. THE SIBERIAN PECTORAL SANDPIPER Tringa acuminata (Horsfield) The Siberian Pectoral Sandpiper is very closely allied to the above. It breeds in Eastern Siberia and is found in winter down the Asiatic coast. Two examples have occurred in England. It differs from the American form in its smaller size and more rufous coloration, while the markings on the breast are arrow-shaped. Length 7·4 in.; wing 5·25 in. BONAPARTE’S SANDPIPER Tringa fuscicollis, Vieillot This is an American species, breeding in Arctic regions and migrating in winter along the whole of the Atlantic sea-board of America. About a dozen examples have been procured in England and one in Ireland. In appearance it is like a small Dunlin, but may be recognised by its smaller size, shorter bill, and white upper tail coverts. Length 7·25 in.; bill 0·9 in.; wing 4·75 in. THE DUNLIN Tringa alpina, Linnæus Of all our shore-birds the Dunlin, or, as it is sometimes called, the Ox-bird, is the most numerous. At all times of the year and round all our coasts it may be seen running about and feeding on the animal life to be found among the rocks or in the soft muddy ooze recently left by the ebbing tide. It is almost always found in flocks, which are often made up of thousands of individuals, and when disturbed from one place they may be seen twisting and turning on the wing in graceful flight, preparatory to settling again on some rich feeding-ground. At times it is most absurdly tame, so that it is possible to walk right among a flock, which will continue feeding or resting as though unaware of the presence of a stranger. Suddenly an individual will sound the little alarm-note, and the whole flock will rise as though governed by one mind, even those who were asleep flying off in full possession of their faculties as though they had been on the alert all the time. In summer many leave us to nest in Northern Europe, while others betake themselves to inland moors or salt marshes round the coast on which to breed. It cannot be called a common nesting species with us, but it has been found in suitable places throughout the United Kingdom, becoming more numerous in the north. The nest is a shallow “scrape” among heather, rough grass, or some other cover, and during the nesting season the male has a pretty little trill, which is generally uttered on the wing as he flies over the nest.
