J.P.Myers 1974 Journal (2416), Estancia Weedland, 35 Km S. of T. vauchoby road, Pte de Madariaga, Ricia de Bs. Aires Argentina. 17 September (cont'd) climbed to the platform just below the whelb, 5m above ground (and 6 m above average local level). Remaind on top until 1815, censusing shorebirds. From the wind will are das an excellent view of the surrounding area (but we must look either east or west, as the platform forces a choice). I looked to the western half of the day, and counted all birds flying in the sky the NE-SW fence line running beneath the windmill (see 23 August may). Habitat overlooked from the wind will include a flint stretch of NE-SW flooded grass - Solanum swamp, extensive Spatina. (also NE-SW) in some places several hundred meters wide, some tide savannas, partly distributed along the W side of the Spatina grove, and the extensive grass fields which extend for over 1.5 km E to Arroyo Chico. Directly along the NW fence line beginning at the windmill, ~2 km NW, are the fields where during 2 recent evenings (14,15 September) we watched upward shorebirds may before going to roost. The 15th I had traced some flocks to the vicinity of the 2nd Wind mill. At 1700 only a few fluvialis were visible ~300m to the W from the wind will.

However I found that a considerable number may have gone undetected because by the time that
