J.R. Myers 1974 Pluvialis dominica (3,2) Estancia Medaland, 35 Km S. of Juanday by road, Pto de Madariaga, Provincia de Bs. Aires, Argentina dawn up to 10am 3 hrs, stopped, and as usually resigned myself to waiting for 10-20 minutes as they took their time in habituating to my presence. It takes so long - and frequently after 10-20 minutes, during which time they have been sitting standing, head bobbing, and calling enough to scare anything else off, instead of returning promptly to foraging, they too fly. Why wait so long? (18,7) Estancia Medaland, Pto de Madariaga, Provincia de Bs. Aires, Argentina more golden than as reflected in sighting records. However it is difficult to know, with golden hues particularly, how to count flocks, the land so patchy that the birds all dispersed, and the majority appear to be territorial. Thus, though from any given hummock I might see 5-10 Pluvialis, the whole 'flock' could extend for 500 m. Usually, however, I never see more than 3-5 flying together at a given time.

Aires, Argentina - good following data on a territorial golden plover grid (ba this morning - see grid data book. Territory occupied ~ 500 m² supported about 3 flocks. One interesting event occurred when a Kiskade (nesting on the tower) flew at this particular golden when the golden faced a large 1" long, thick grub (very typical fare for goldens here - see them taking the grubs often). The golden flew, with the grub, over 150 m to NE, landed, and was supplanted twice in succession. It then flew past us, 150 m to the SW side of the tower, circled, + came back to land on the territory. It then ate its grub. (2,17) Estancia Medaland, Pto de Madariaga, Provincia de Bs.
