JPMyers 1974 Journal Grid 5 (Tower Llano), Estancia Medland, 35Km S. of Janela by road, Ptdo de Madairaga, Pcia de Buenos Aires, Argentina 15 January Up at 0245 - had to drive 3 or so bulls away before putting out nets. Their three following quads were 15 mins. before the alarm was to go off. 2 Nets up - one (brown, 7'x42') immediately jumped out from tower on average at "mouth" of the little wash that drains in here - 1 to arrayo. Another 50 m downstream, again 1 to Arrayo. When I went out to put up net, 2 lapurings, and also found one solitario WR along the mouth of the wash. Moon was full (decreasing) and at 0245 was ~ 1100 in sky. Temperature at 0400 - 8°C, clouds 0%, wind very light from NE. Charadrius falklandicus heard calling between 3+9 am. Aragus sybillinus (along with lapurings) most vocal app. all their hours. Red winged tinamou began calling just before 0400. 0415 first detectable increase in light level along E horizon. 0430 - first G. down. By 0445 shorebirds sounds were thick, esp. 6 p.m. + lapurings. To my surprise I heard only one WR before light got high enough. Yet at 0530 there was a flock of WR feeding - either they had roosted there, or they had flown in quietly. Bridge WR the other common bird along the shore was Chrysolophus By 0545 I had caught 1 WR, and walked along the shore + managed to herd 6 more into the net (60'). Before dawn (0445) caught a lapuring in 60' net. Grid 4 (Tower Llano) Estancia Medland, Ptdo de Madairaga, Pcia de Buenos Aires, Argentina After coffee returned to the car (0630) - surprised to find we almost surrounded by a flock of 10 Buffin (~20), Golden (5) and WR (!!--3) foraging in the grass. They spooked at mystery close approach (<20') and flew onto Grid 4, joining others there previously already there. 20' buffin on the grid !! And on Grid 7, also short-grass Veneros, then were more buffins interspersed among the cows. 3 more WR foraging with them in the dry grass. Facultad de Agronomía (1 km W of Farmhouse on Farmhouse road), Estancia Medland, Ptdo de Madairaga, Pcia de Buenos Aires, Argentina 1540 driving along road toward turnoff to Tower Llano we spotted a flock of ~10 WR in puddle on N side of road. The puddle was formed several months ago by the Estancia's tractor digging out fill in order to increase road height in the area. If (the puddle) had been dry, but
