J.P. Myers 1993 Journal 2 December cont'd Arroyo Chico Bridge, Estancia Medeland, 35 km S of Juancho by road, Pcia de B.A., Argentina After the last count we went to Grid #2 at Rte 11 Pond in order to finish placing stakes and painting numbers. Several Pectorals (see ap accent); little else. On the way back to camp We stopped at the bridge over Arroyo Chico on Farmhouse Rd. Looking N in the arroyo Observed a flock of LY legs, Hogdirls, and we, sitting on the mud by the water. There were ~15 WR (although blue may have been snow; they would be picked out), most of them preening Rte 11 Pond (Grid #2), Estancia Medeland, 35 km S of Juancho by road, Pcia de B.A., Argentina First sample 0630 At Grid observation post 0600. Temperature mild 57° with a slight NNE breeze. Clouds NE horizon ~20%. Stayed taking grid counts until 0830. 8 samples taken at 15 min. intervals. During that time temperature rose slightly to 70°, the wind picked up sharply, and cloud cover increased to 80%, with a low threatening cover coming from W. Totals (format = sp, even/amount, total) range Pectoral Sandpiper, 3, 2-4 (24); white rump, 0.25, 0-1 (2); LY legs, 2, 0-5 (16); GY legs, 0.25, 0-1 (2); Southern Lapwing, 1.25, 0-3 (10); White-faced ibis, 0.95, 0-4 (6); Neotropic carmorant, 0.18, 0-1 (1); Sicalis, 0.18, 0-1 (1); Phleocryptes, 0.13, 0-1 (1). These totals are made without consideration of the possibility that the individuals recorded in different counts may be the same bird. For example, I am fairly certain that no more than 4 Pectorals were feeding on the grid during the whole observation period. In addition to species recorded on the graph, within the vicinity were roseate spoonbill, southern screamer, golden plover, buf-breasted sandpiper, Carrancho (4 flew over during 2 hrs, each time being chased vigorously by lapwings), chimango, Anthus correndera, Kiskadee flycatcher, Farmhouse pond (Grid #1), Estancia Medeland, 35 km S of Juancho by road, Pcia de B.A., Argentina 4 December we camped on the observation post. Up into blind at 0530, first sample taken 0600. Temp 62°, clouds 100%, wind strong from NE. It rained lightly between 0400-0515, and continued to sprinkle intermittently while down in the blind. 3 counts made - 0600, 0700, 0730. Temp dropped 1°. totals (format as above): Pectoral 1, 1 (3); white rump 2.3, 0-4 (3); Stilt sandpiper 0.67, 0-1 (2); Golden plover 0.3, 0-1 (1); LY legs 0.3, 0-1 (1); Brown-headed gull 1.3, 0-3 (4). I was very discouraged by the paucity of shorebirds using the grid this morning. There was only one Pectoral present; I was able to follow
