JP Myers 1973 Journal Grid 3, 500 m N of Farmhouse, Estancia Midland, 35 km S of Tucumano by road, Pucia de B.A., Argentina 12 December cntd is now passable in auto, the first time in a week plus. Much of the surrounding grass, especially in hollow [illegible] is in shallow ponds of water. In the major pond along which Grid 3a-b-c, in grand view was a large flock of shorebirds, mostly between 3a-b and 3c. In the fields were Lyleg (100+), C4L (30), WR (<30 - most near 3c, on the S west side at the edge of the lagoon), Pectorals (50+). On the way out tapping did their thing, moving our incorrectly. They are a definite obstacle to any study, as the other shorebirds appear to pay attention to the movements of the tapirings, and go off. This was the major problem this morning. Birds were on the grid, but on all but two instances they began giving alarm calls before I could get close enough to sample. L & G Lyleg are much spookier than Pectorals. As I was concentrating on approaching the birds, especially near c, several times I flushed small groups or solitary individuals out of tiny puddles, a few fat actors with no open water - just half-submerged grass. Also 3 Gallinago g. And one flock of ~30 Pectorals. The actual counts in the grids were not that profitable, despite the abundance of birds in the vicinity. I am sure that, had I not been spooking them, and had I remained longer, eventually in all the grids flocks of Lyleg would have appeared. The actual tallies: Grid 3a: Lyleg 2 samples of each subgrid (3a, 3b, 3c) between 0745 and 0815. 3a: Lyleg 0.5 (0-1); Kiskadee 0.5 (0-1); Spectacled tyrant 0.5 (0-1). 3b: Lyleg 1.5 (0-3) ; Pectoral 0.5 (0-1); Spectacled tyrant 0.5 (0-1). 3c: Lyleg 2 (2-4). On 3a the birds seemed most sensitive to my presence, especially for the second sample. 3b was least sensitive. Other shorebirds seen flying near grids - william phalacrope, golden plover. Tower Llamas and Arroyo Chico, Estancia Midland, Pucia de B.A., Argentina At approximately 1300 we drove out to the tower in order to grid areas on the adjacent arroyo. No traffic visible on Grid 9, but many between the road and the tower. Large flocks of gulls still evident, and we scared pectorals out of puddles in the fallow cornfield. There is still much surface water in the Llamas. Cows were all around the tower and on the grid, scratching. Our activity here may have incurred the attentions of the immediate area cattle because we have provided convenient scratching posts. The cattle obviously use them, as the
