J.P. Myers 1994 Journal (2,3) La Orqueta, Estancia Medaland, 35 Km S. of Javendo by road, Ptdo de Madariaga, Pcia de Bs. Aires, Arg. 'withering away' - narrowing to a thin <5 m strip in the center of oogy mud. Peeps occur here and along the border of open water areas in other portions of the pond. The shorebird community has changed considerably: Baird's sandpipers are essentially gone, so are Charadrius falklandicus. I saw the following species: Calidris paerdi 3 Calidris fuscicollis 164 Limosa haemastica 8 Tringa flavipes 15 Himantopus himantopus 4 The change in Baird/WR ratio is striking (as previous exp. to La Orqueta) I began to observe WR, especially searching for banded birds (none) but was deflected by a tremendous spoonbills in the sandpipers, alerted by pernicious Vanellus and Larus maculipennis. As I approached the birds they would continue foraging, but slowly gather into a tightish + tight flock. Finally, almost invariably, they flew. (8,12) & (11,17) Arroyo Chico, Estancia Medaland, 35 Km S. of Javendo by road, Ptdo de Madariaga, Pcia de Bs. Aires, Arg. 1740 drove toward Arroyo Chico, passing through the (9,10) quite and entering the Arroyo in (8,12). Strong S wind blowing all day, 100% clouds, temp ~ 9°C. Arroyo level was down lower than it was just previous to the last major rain, i.e. lower than it has been all spring. We drove after an subadult of (4) fuscicollis / paerdi flock, Reducing reaching the north fence of Torres llanos at 1749. See fuscicollis accent re: flocks seen (see a new, returned banded bird!) (13,13) Estancia Medaland, 35 Km S. of Javendo by road, Ptdo de Madariaga, Pcia de Bs. Aires, Argentina. Parked in 13,13 within 200 m of the 20 September Tryngita roosting site at 1745. N/L at that time = 750 ft. We remained in that vicinity until 2030 trying to capture Tryngita with a portable Car headlamp which I borrowed from our car + rigged for hand carry. Late during the session, just before it was too dark to see flying birds, we lost track of the major traffic flock. Although we did find it again later, it was only by accident, as we stumbled across them in the dale. As a result, we caught none. Details of the evening roosting flight: 1757 we saw Major
