JPMyers 1973 Journal Arroyo Chico near Tower Llanos, Estancia Medeland, 35 km S of Juancho by road, Pucia de Buenos Aires, Argentina 17 December contd Came to tower 1200 to place [illegible], repair Grid 4, and enlarge it. Most of the surface water through which I've been shidley for the last few days en route to the tower is now good gore. [illegible] However, as near camp, and around Grid 3, the mosquitoes in the Llanos are becoming a [illegible] trial. Absence of wind this morning accentuates their [illegible] perverseness. Buffalo and galdons both very apparent on the Llanos, but winter are traveling in the large flock seen during the last week. Few WR were on the gridded area nearby from the towers in the Arroyo; 2 buffaloes were bathing. There were Gplover, Hgadwit, Lykaga, Ch. Falklandica. Water in the Arroyo has receded ~ 2 horizontal feet, or several inches of vertical. This is partly due to the absence of the usual S wind, which seems to pick up the water. From the tower, I went back out to the road, I saw the Bridge, and then N again to a point on the Arroyo across from the towers, in order to mark observation post for the linear transect in the Arroyo, Grid 8. Lapwings were extremely annoying; at one time I had 6 hounding me, plus two brown- headed gulls. They will make walking the transect very difficult. Grid 9, Farmhouse Puddle, Estancia Medeland, Pucia de B.A., Argentina Lais drove me out to the observation post, me in thigh on top of the car in the blind, at @ 1615. Slight rain, moderate - strong wind from NE, very dreary and low clouds, temp = 65°. Took quist count at 1630. Our arrival did not appear to affect the birds whatsoever. Two flocks, one of WR, and another of LYL, remained foraging between the car and the grid. A few speckled teal flew but returned shortly thereafter. Totals (species are #/sample [range], total #): Pectoral, 9.6 (0-20), 67; Whit-rump, 5.1 (0-20), 36; Microspalax, 0.3 (0-2), 2; Lykaga, 6.4 (0-14), 45; Gplover, 1.7 (0-5), 12; S. lapwings, 0.9 (0-2), 6; S. screamer, 0.3 (0-2), 2; Speckled teal, 1.6 (0-5), 11; Kiskadee, 0.1 (0-1), 1; Speckled tyrant, 0.1 (0-1), 1; Cattle tyrant, 0.1 (0-1), 1; Anthus correndera, 0.2 (0-1), 2. Chimangos (Milvago chimango) and ~30 w. thalarpops feeding in (0-1) WR swallows flew overhead frequently. A flock of Hgadwit foraged in the 360 area between- swampers. The Pectorals observed on the grid evidenced no territoriality, although one in the (-1,-1) area appears to be so [see op. accent]. In the -1,1 and -1,2 area a pair of
