JRMyers 1974 Calidris melanotos 25 Km S of Clorinda by road, Pucia de Formosa, Argentina 3 August 6!! six pectorals flying south into a S wind at about 10:30, flying at a height of [illegible] meters. today is the first day of S wind for our 2 weeks. In fact, the last 2 days have been clouded by very strong W winds. The pectorals did not continue in a S direction, but after a few minutes began circling, and finally they flew W out of sight away from the road. They were not acting like birds that were accustomed to that area — rather that they'd just arrived and were exploring. Whoopee. 40 Km NW of Victoria by road, Pucia de Entre Rios, Argentina 13 August at dawn found pectorals foraging along the edge of vast river-swamp systems, in an area muddled by cow prints, creating a mosaic of mounds + valleys just larger than the birds body. The Pects were concentrated in an area where there were considerable Indian weed, + reeds worked into the gilled substrate. Very spooky, no sign of intra-specie aggression. Estancia Medaland 35 Km S of Tucacho by road, Pob de Madariaga, Pucia de Bs. Aires, Argentina 23 August Pectoral habitat dry - absolutely (see journal 22 August). But at 11:30 found 3 Pects foraging in a shallow spot in the middle of the Arroyo. Promptly collected one. (45) 6 Km NE of Farmhouse, Estancia Medaland, 35 Km S of Tucacho by road, Pucia de Buenos Aires, Argentina 25 August # a fantastic stretch of pectoral habitat (see journal). When we first found it at 15:30 there were only ballinago. But at 16:30 a flock of 10 pectorals flew by as we were beginning lunch right in front of the 2nd Windmill. The pect's turned, flew downstream (SW) 150 m, turned again, whirling up past us. They continued moving back + forth, touching down every few minutes but taking off immediately. They finally landed in the driest (i.e. no surface water) area, stayed alert for 15 min, and then began feeding. The flock remained fairly tight on the ground. We watched them feed for 10 min when another flock of 7 flew by, then on the ground flown up + joined them, and then the 17 came down + landed where the others had been feeding. Within 2 mins they bolt off. No interactions with either the ballinago nor the Vanellus which were nearby.
