The Golden Plover appears to be most abundant on the pampas between the thirty-fourth and thirty-sixth parallels of latitude, but how far south its range extends has not yet been ascertained. The return migration begins early in March, and yet Mr. Barrows met with it in the neighbourhood of Bahia Blanca and on the Sierra de la Ventana from February 8 to March 19. During most of this time he says it was abundant in flocks of from twenty to two hundred birds, which appeared to be moving uniformly _south_ or _south-west_. 388. EUDROMIAS MODESTA (Licht.).

[Illustration: WINTER PLOVER. (Seebohm's 'Plovers,' p. 105.)] _Hab._ Antarctic America. This species in its gait, flight, and general appearance closely resembles the American Golden Plover, but is smaller than that bird, and its sober upper plumage is unrelieved with flecks of golden colour. It breeds in South Patagonia and the Falklands, and migrates north in autumn, appearing on the pampas in April, and being met with there throughout the winter; hence the vernacular name _Chorlito de invierno_ (Little Winter Plover). In its winter dress the upper plumage is greyish drab colour; the breast dark brown; the belly white. It is shy and active in disposition, has a very rapid flight, and is seen in flocks varying greatly in number, from a dozen to two or three hundred individuals. When feeding the birds scatter very widely, running swiftly over the ground in all directions. When on the wing it frequently utters its cry, which has not the mellow tone of the Golden Plover's note, but it is wonderfully clear and far-reaching, and impresses the listener with its wildness and melancholy. Their return migration takes place in August. 389. ÆGIALITIS FALKLANDICA (Lath.). (PATAGONIAN SAND-PLOVER.)
