J.Phillips 1974 Journal (3,13), Estancia Medeland, 35 km S. of Juancho by road, Pato de Madalinga, Proia de Bs. Aires, Argentina 22 September (cont'd) flock of Tryngite + Ploviatis, presumably) take off from (9,18) region. 1VC at that time = 600 ft. They whirled over that area for several minutes and then apparently landed in that vicinity. There were at least two large groves, visible from that distance (2.5 km) against a sitting soup. 2 obvious size clears. 1803 5 Tryngite appeared in front of us (1VC = 500 ft.), flying around, apparently holding but not landing in the 20 Sept. roosting site. 1865 Cinereous harrier going over. 1VC at 1810 = 2400 ft. 1810 - 3 Tringa f. going over and 10 Tryngite beginning to circle, going down in the roost site and last year at the edge of a patch of Salamanca, in trampled short-grass. 3 more Tringa at 1815. Buffle at 1816. 20 buffle going toward Tower (Viano) swamp and beyond - 1816, going down beyond now fence butt before Sparkina. 1820 1VC = 260. golden going over them and a Tringa, 1825 6 WR. Flying toward 2nd windmill, 7 Tringa at 1826. 1827 4 WR. + 8 Tringa. 1828 6 Tryngite. 1829 big flock of peces over tower (Viano) 1830 5 buffle went down exactly on last year's roost site. 1VC = 130 ft. at 1830. 1832 30-40 Tryngite flying low over 22 Sept. roosting site. 20 WR flying by in distance. 2 Ploviatis with buffle flock, which is still flying low over area used 20 September. Described as figure 8, flying 200 m + beyond. 1835 (1VC = 80 ft.) the buffle flock went down of 20 Sept site. 1836 18 WR going off toward 2nd windmill. 1838 buffle group allows started to feed after sitting quietly all Sunny E. 1838 the flock took off. At this point I stopped doing anything but following the major buffle flock. They eventually landed ~ 500 m E from the car, just W of a bare-mud part of Tower (Viano) swamp in Distachio. It was approximately at 1840 that goldens became very numerous in the air, including a flock of 30-40 which landed where the buffles had been. At ~ 1910 4 Rheas scared the buffles, and I lost them as they flew. We found much later, that they had landed in the same area. 10/13 (8,10) Fe (3,24) Arroyo Chico, Estancia Medeland, Pato de Madalinga, Proia de Bs. Aires, Argentina 23 September 0640 lift for Arroyo Chico via 8,10 gate. Sun up before 0644. Slight-mod E wind, 100% cloud cover, temps 79C at 0600. Reached (10/13) at 0655. see sighting records. The wind has receded; bared water in the Arroyo, exposed a corner hat, exposing a few new areas, throughly shifting the water edge from E->W by several horizontal circles. But in
