J.P. Myers 1974 Journal Tower Llanos, Estancia Medaland 35 Km S. of Juan de la Cuesta by road, Pto. de Madariaga, Provincia Bs. Aires, Argentina 20 September 1700 drove to Tower Llanos in order to search for Tryngite roosting areas. Last evening from 19.45 we had seen buffins apparently landing in the (0,12) region. Accordingly, we drove to the area, parking in (15,11) in order, hopefully, to observe without being a disturbing factor. Temperature: 17°C, 100% cloud with a NE breeze. We reached (15,11) at 1720, at which time IVC = 500 ft. Shortly after we arrived intense rain (sprinkling) began, continuing until 1930. Both sp. tetramor (Rhynchobotes refusus) and Nithura muculosa are very active, calling all evening. Dawn: During the early morning we watched the western + southern horizons for shorebirds, recording sighting records. By 1745 T. tryngite appeared regularly, most flying in from the SW (IVC at 1745 = 400 ft). At that time a large flock of buffins (50?) came in from beyond Tietepars Cornfield i.e. the NW and the (0,18) region. See Tryngite sp. accent. When the buffin flock landed in (14,13) we moved to within 180 m (1806). From that site we found not only the roosting buffins, but also saw large flocks of Pluvialis flying, and small groups of buffins flying low in many directions over the lances. [See Tryngite sp. accent for tale of mobile rest aggregations]. Banded 2 buffins [see banding schedule]. The vegetation in the (14,13) → (15,11) region is marked a transition from short grass → dry patches → very thick high grass → swamp and bare mud → thick, high grass → short grass. The buffins were on the edge of the short grass zone, moving into the taller + thicker grass. These transition zones are a common habitat on the Estancia, so there would not appear to be a shortage of roosting areas. (23) La Orqueta, Estancia Medaland, 35 km S. of Juan de la Cuesta by road, Pto. de Bs. Aires, Argentina 22 September 1215 drove to the nearest point on Medaland to La Orqueta and walked to the holding pond (see map 13 September). A moderate SW wind blew throughout the evening, continuing into afternoon. Clouds increasing from 10% cover. Temperature ~13°C. The holding pond has dried beyond its state beyond the last rains, making it drier than I have ever seen it. In one place, several hundred makes of the toke stand, dried low ascended and dried across the surface. However there is no other as guanaying crossing, but the prime areas of shorebird feeding (prime 10 days ago) appear to be
