JPMyers 1974 Journal Estancia Medaland, 35 Km S. of Juancho by road, Ptdo de Madaniaga, Pcia de Bs Aíres, Argentina 8 September (cont'd) From Grid II we crisscrossed the fields between the Arroyo and Rk II as far north as Rk II bridge. Then we forded the Arroyo, and explored the uplands from (24,30) SW to (21,27). There were only a few Zenilbyx and Oreophobus, mostly quite near the inmunde which border Arroyo Chico. Some areas in here appear as if they are suitable for Tryngite. At 17,27 we crossed through a gate, and followed the Arroyo (again in the surrounding upland fields) SW to the next fence, paralleled that as required to reach a gate to the SE, returned NE to the Arroyo, and continued this tactic to Tower Llanos north gate (17,17) and then struck SE out across the llanos, skirting the plowed field. Finally, we passed through TL south gate (9,10) and returned to the camp mate. Returning, the only areas where we saw Oreophobus were in the fields around (14,22) [see journal 26 August]. There were also Zenilbyx and baardii hue. Nothing on tower Llanos in the way of shorebirds except several Vanellus pairs. Peeps common in the Arroyo along the water. Note: the very strong S wind is having great effect on water distribution in the arroyo bed. Water level at the grid has receded 5 m!! to where it cuts through the middle of (n,1). (2,3) La Orqueta, the Estancia Medaland, 35 km S. of Juancho by road, Ptdo de Madaniaga, Pcia Bs Aíres, Arg. 10 September reached banding site 0445, the same set of mud where I banded 5 September. Sky clear, very light N breeze, temp = 33° at 0400 but decreased to 0° by 0700, at which time the dawn the nets froze. C. fuscicollis, and C. baardii, and Charadrius falcklandii, roosting in La Orqueta area; we specked birds out of depurarios in the mud as soon as we got there. As far as I could tell there were roosting solitarily, and we never came upon a center. Numbers of proper storm from 5 September, with less than 75 total. 16420 10-15 Ch. falcklandii. After Charadrius melanotos, >10 Pluvialis flying over; 2 Steganopus tricolor. No Zenilbyx. Netted 1 fuscicollis, 1 melanotos, 1 falcklandii. Water level down slightly, but the mud is still half-deep. It appears that the shore birds are not becoming very active until past the time when they can detect the net. Do this because of the low temperature or the fact that because they roost there they don't have to fly and therefore can afford a later start
