Grid 9, & Farmhouse Puddle, Estancia Wedeland, Pcia de B.A., Argentina 1450 23 December Lois drove me to the observation post and walked away from the car. It was immediately apparent that the grid had changed from its condition 20 December, at least as indicated by the distribution of birds. In (3,0), when 20 December there had been Pectorals and White-rumps, there were a few gulls present with more of the others. Weather on arrival was typical of the last few days - clear, (10% cloud cover), warm (24°C) with a moderate NW wind. Grid totals: Pectoral 415 (27-65) 360; White rump 42 (4-42) 91; Micropalama 8.5 (0-68) 68; Cylegs 0.75 (0-1) 6; Lylegs 1.9 (0-3) 15; Golden Plover 11 (6-16) 88; Wilson phalarope - (0-1) 1; S Lapwing 1.5 (0-2) 12; Ybquitail - (0-1) 1; W Faced lark - (0-1) 2; Pizururo pujon - (0-1) 1; Speckled tyrant 1 (0-3) 8; Forktailed tyrant -0 (0-1) 1; Kiskadee - (0-1) 1; Molothrus bonariensis - (0-1) 1; Correndera pipit 3.6 (0-7) 29. The shorebirds struck me as being more congregated from the when I arrived than they had been during the last observation period, and I was fairly sure that my arrival did not cause a significant disturbance on the gird. Lapwings activity was again a significant feature of the dispersion, especially in the (0,0) area. I was unable to obtain sample birds past 1940 because of light levels. A large thundercloud to the SE observed the sun prematurely. 1930 a flock of Micropalama plus a few with Stewart grid. They remain (less than 10 minutes fortunately at a sampling time). After they left the other shorebirds began flicking and taking short flights, returning to the grid. One flock of WR did this twice. It looked as if they were preparing to leave. However, by the time that I left (2000) they were still on grid foraging. Throughout the observation session there was a small group of resting (offing ground) shorebirds in the area immediately to the E of the grid (Little Lagoon (5,0) approximately) - Golden, White rump and a few Pectorals. Temperature down to 26°C at departure, coincided with good NW, 50% cloud cover.
