166 BULLETIN 133, UNITED STATES NATIONAL MUSEUM Aires, on June 29, 1920. At Zapala, Neuquen, on December 8, I shot a juvenile specimen just able to fly from a family that was runninf^: about in the closely cropped grass of a pasture near a tiny stream. Two broods were recorded at Ingeniero White, Buenos Aires, on December 13, while on December 15 and 16 several were seen on the shore of Lake Epiquen, near Carhue. An adult male was taken on the 15th. Between Montevideo and Carrasco, Uruguay, a few were recorded on January 9 and 16, 1921, on sandy beaches where they fed at the water line by thrusting the bill quickly in the sand. One was noted at La Paloma, Uruguay, Januar}^ 23. Near Guamini, Buenos Aires, they were fairly common on the muddy shores of the Laguna del Monte from March 3 to 7, in company with sandpipers. Two immature females were shot March 4. Half a dozen were seen at Concon, Chile, April 25. The Falkland plover inhabits sandy beaches on the seashore or the borders of open lagoons inland. In habits and appearance it is similar to related species and like them frequently squats and hides to avoid detection. The ordinary call is a sharp jnt fit. PLUVIALIS DOMINICUS DOMINICUS (Muller) Charadrius dominicus Mullee, Natursyst., Suppl., 1776, p. 116. (Santo Domingo, West Indies.) Golden plover arrived at Kilometer 80, west of Puerto Pinasco, Paraguay, on September 6, 1920, and continued in southward pas- sage until September 25. The birds came to the open shores of lagoons with other sandpipers, but were more often seen in flocks of 30 or 40 scattered over open savannas where the grass was not too long. At this season they were rather silent and were very wild. On September 16 cold weather in the south drove many back on their route, and birds passed north during the entire afternoon, not pausing to alight though the weather at the point of observation was not unfavorable. The return southw^ard began two days later. On September 24 and 25 flocks were seen at Laguna Wall, 200 kilometers west of the Paraguay River. The Anguete Indians called this species pill toil. On October 23, near Conessa, Buenos Aires, small flocks were scattered over the open pampa and the number seen was estimated at 260. On November 6, 7, and 8, golden plover were scattered over the open camp back of Cape San Antonio and a number arrived from the south. On November 13 and 15, I found a considerable number near the mouth of the Rio Ajo and on November 16 about 30 were recorded in crossing from Lavalle to Santo Domingo. December 13 a golden plover was seen on the mud flats near Ingeniero White, Buenos Aires; December 14 thirty were seen near Saavedra, and from December 15 to 18 a few were noted near Carhue.
BIRDS OF ARGENTINA, PARAGUAY, URUGUAY, AND CHILE 167 The species was not found west of these points and seems to be restricted during the resting period to the better watered grassgrown eastern pampa. The northward migration began with a flock of nine seen January 23, 1921, at a little fresh-water pool on the beach near La Paloma, Uruguay; when flushed tliese passed on to the west. Single indi- viduals were seen near San Vicente, Uruguay, in flight toward the northwest on January 24 and 30. At Lazcano, Uruguay, birds in passage north were seen in early morning on February 7 and 8, and one was recorded February 18 at Rio Negro, Uruguay. On March 8 at Guamini, Buenos Aires, 15 'came in at dusk to roost on a little mud bar in company with Hudsonian godwits. The migration seemed almost at an end then, as later I saw only four at Tunuyan, Mendoza, on March 23 ; and on April 5 only a few were heard calling with other shore birds in flight northward over Tucuman, Tucuman. An adult female shot September 6 had renewed part of the body plumage but had the flight feathers still worn. Another, shot November 15, was nearly in winter plumage and had begun the molt of the inner primaries. OREOPHOLUS RUFICOLLIS RUFICOLLIS (Wagler) Charadnus 7-uficollis Wagler, Isis, 1829, p. 653. (Canelones, Uruguay.) The spelling of the generic name for this plover as proposed by Jardine and Selby ^^ is Oreopholus, as given above.^* Brabourne and Chubb ^^ state that no type locality has been given for this species and suggest Patagonia. In Wagler's original description, however, is the statement "Habitat in America. {Canelonnes.) {Miis. Berol. ),'''' which indicates Canelones, Uruguay, as the source of his type. Uruguay has not been included usually in the range of this species, but Oreopholus 7-uficollis was seen by Aplin^^ at Santa Ana, and is recorded by Tremoleras^^ in Montevideo and Canelones. On December 8, 1920, near Zapala, Neuquen, while traversing a sandy area with a thin cover of low bushes my attention was at- tracted by a low plaintive whistle, lohees tur tur. As I watched to determine the source of the sound one of these plover ran forward a few steps and then stopped to watch me quietly. In this bird, an adult male, the tarsus was pinkish vinaceous, and the toes black.
