J.P. Myers 1973 Journal Farmhouse Road from Arroyo Chico to Farmhouse, then N across country into Estancia Meekland, Aviande Buenos Aires, Argentina 24 November cont’d Yllags, WR, and Redshanks. A definite suggestion — more than a suggestion — of territoriality in the latter species on their ponds. Also 13 Still Sandpipers. The ponds are in the process of drying — well along in that process, with several feet of caked mud along the periphery; Several type of thrushes in a field of the short grass variety, and have around them a type of emergent vegetation spread sparsely along them. The cross-country trail we took parallels a continuation of these ponds. But the contour does appear to become a much more substantial body of water (not visible from trail) because of the presence of large water birds — e.g. coomorants, swans, storks etc. Tule, plus the edge which is so abundant near the sea around here. The trail itself is in a slightly rolling field of short grass, complete with buffle and goldens. Fit drink & oat on top of the roof of the car and remained there until binoculars were no longer functional (7:30-8:45). Could sleep alone if I could spot white bud were rooking, or at least the direction. No birds flew east over me. Many goldens flew over to Rio V, and dropped out of sight — perhaps a kin or feather. Over 100 Goldens were feeding! until I could no longer discern their movements, in the field around the car. No suggestion of roosting, except for the fact that they appeared to be more closely packed (and that there were “roosting flights”). Buffies could be seen roosting less than 100 m away in the middle of a small short grass field (see sp. acct.) 25 November I got up at 0530 and took a short walk to the N from camp where I had seen WR flying over the night before, [illegible] Dawn was clear, windy and cold (34°F). Sunrise ~ 0530. Less than 500 m from camp was a small pond with a large development of tule on its N shore. Nothing looked like prime shorbird habitat, although thought I heard a [illegible], WR and Yllag flying overhead. Several spp. of duck, Philomachus, etc. To the NW of this pond, less than 200 m, was a much larger body of water. Again nothing like prime shorbird habitat. Rollands and Great Grebes. Several Maguari storks along the edge. Agelaius philippei fledging in the tule. Several flights of WR, Yllags, and Haploptila. Both Coscoroba + B-necked swans
