JPMeyers 1974 Journal Grid 9 (Farmhouse Paddock) Estancia Meceland 35 Kms. of Juanadas, Partido de Madariaga, Provincia de Buenos Aires, Argentina 1 January (cont'd) In addition to those I netted 2 Slapwinga and 1 Sicalis. Rained (briefly) about 2200. During the night (in wind) became steadier. 2 January Rained continuously most of the night, and steadily all morning until 1330. Accumulated 41mm. At 1330 sky cleared 100%, and remained that way without wind until 1830 when Cumulus started pouring in from the west. Still little wind. At 1900 I walked to grid 9 — the rain filled the area (grids 1+9) up to a point similar to that achieved by the rains of 4-6 December. [illegible] Few birds on the grids. Found one dead banded white-rump (Right Orange, Left Yellow B21 52017) and one live bird that couldn't fly (orange orange) [illegible] -050,059 Picked them both up. Unfurling rats, headed a ball more + encourage away, and retired to a vantage point. Compared to last night's abundance of shorebirds, tonight's paucity is alarming. Did activity change the roosting area? Or did they move because of the rain (incurved water level making other roosts more desirable)? The only birds which lighted were a group of hudsonian godwits and another of Gylp. Heard very few white-rumps and fewer Pectorals. Caught one Southern lapwing — nothing else. Grid 3, Estancia Meceland, Partido de Madariaga, Provincia de Buenos Aires, Argentina 3 January 1700 walked from Farmhouse north through Grid 3 and to the first windmill, ~500 m W of Farmhouse. Warm (in high 70's) with the wind not strong enough to keep away hordes of mosquitoes. No clouds. I went to secure the area after yesterday morning's defense; the effects were obvious but not quite so overwhelming as I had expected. Water level near that of 6 December. I had not been in this area for over 2 weeks, and was struck by the luxuriance of the lowland vegetation — nearly 6'8" grasses and sedges (Juncus spp.). Spoke several (all male) from the flooded grasslands. Few shorebirds — one flock (<10 birds) of Lygge, a few Gylp, and 3 Pectorals on the grid. At the northeast of the grid the brush edge "hedge" [which serves to separate the gridded wider body from a large lake swamp to the west] juts out — and the gridded pond almost reaches the lake swamp. Here, on the frond of the swamp, was a flock of 15 WR, a
