J.P. Myers 1974 Journal (11.) to (2,3), Estancia Medaland, 35 Km S. of Juancho by road Ptdo de Madariaga, Provincia de Bs. Aires, Argentina 26 September (See map 13 September) The Sun appeared on the horizon at 0634, temp 8°, 0% clouds, light wind. I left Camp at 0710 and walked fairly directly to La Orqueta (2,3). Today there was considerable water remaining on the surface from 24 Sept's rain. However, this was not enough to do more than leave a trace of water in many of the swamps and low areas. Curiously, in lighter lying puddles near larger lower areas which last year contained rainwater, there is more water down in the low areas themselves. The La Orqueta holding pond did rise noticeably, there now being a thin, almost continuous strip of open water running the entire length of the pond. Down below the earlier dam, the old Arroyo bed is also much fuller, covering most of the sand and mud that previously had dominated the area. Along the borders of La Orqueta holding pond, the 'ditches' inlets were saturated, some with standing water, and most, when crossed had trails, with micro mosaic ponds 3-4" across. I [illegible] arrived at La Orqueta at 0830, and remained until 1100. By then, a fine wind had come up out of the SW, making walking in that direction difficult. It is one of the strongest winds we have had here. Temperature rose to 17°C. Sky remained clear. See sighting records + camp list for species seen. Also see [illegible] fusciolla sp. accent (one new, returned WR-Loy) 19.9 Estancia Medaland, Ptdo de Madariaga, Provincia de Buenos Aires 1615 left for La Manga (19.9), driving from camp, with the intention of trying to spotlight roosting sandpipers. The wind had dropped somewhat from this morning's bluster, clouds <10% and temperature -14° at 1600. The area between Farmhouse Monte and La Manga show the effects of the last rain—several new puddles exist, most of them lying along the border between the hummocky, sand dune (vegetation covered [short grass]) and the Spantina lowland lying to the west. Reached La Manga at 1700 (see sighting records re [illegible] - Pluvialis melanoleuca, fusciolla, Tryngites) ATM I observed a Tryngites flock until 1800 (see sp. accent) and then began recording flights of shorebirds into the roosting area. See flocking accent re details and habitat description. Over 350 shorebirds roosted there. Failed to spot light any; it appears that the light is not bright enough.
