S P Myers 1979 Journal Estancia Meekland, 35 Km S. of Juancho by road, Ptdo. de Maclariaga, Provincia de Buenos Aires, Argentina February 11 January cont'd Weather during this outing was generally overcast, with low clouds coming in a wind out of the W. Temperature was warm, in the low - mid 70's. February 12 January Up at 4 to met-raid) picked up + drizzle started with a sharp drop in temperature 30 I decided not to. Instead walked S from camp in the Pampas grass beyond the poplar stand and collected a juncariid (074) Arrago Chico, Estancia Meekland, 35 Km S. of Juancho by road, Ptdo. de Maclariaga, Provincia de Buenos Aires, Argentina. 1500 drove from camp through Tower Llamas to the Arrago, coming out on it at the tower. Drove from the tower to the far end of the linear grid, 3 km N along the arrago, looking for banded WR. Then returned via the same route (driving on the edge of the sand along the arrago), searching again + at the same time making a careful count of WR along the water's edge. In the 3 km found 64 WR foraging, just beyond the S most unit of the gird, i.e. at the bend in the Arrago visible to the S from the tower, came upon a flock of 17 roosting, feeding, preening and feeding WR. 3 banded birds: R Yellow L Green (was where I found them yesterday); defending a territory on one of the grid units; R Red L Red - banded 27 January Grid 30 was in Grid segment #2; R Yellow L Red - banded 3 January Grid 31 - was in Linear Grid sub-unit #1 by the tower. Also, a small flock We remained by the flock of WR for over one hour, trying to catch a glimpse of their legs as the raking sun passed, judged etc. No more banded birds apparent. A boffice came down to the Arrago from the E to drink + bath during this time period. Many Brown-headed gulls present, 2 B-N Skimmers, a small flock of BN Stiks, and over 30 Chalcoiris fallenderian were in the close vicinity of the WR flock. By the time we left the WR flock had dwindled to a total of fewer than 30 birds - thus having apparently flown to the E, departing in small flocks of up to 10 birds. Before reaching the flock we had seen 2 Prolaeis & squatarola ! - a first for the Estancia Hingan, and 4 other players. Tower Llamas Estancia Meekland, Provincia de Bs. Aires, Argentina From the Arrago wedrove E across the Llamas ~ 2 km until reaching the swamp where I had been yesterday (although on the opposite side) Parking the car, I got on the roof to watch for shorbirds. Temperature in low 70's, wind from S, with low dark clouds coming in with the wind. From the NW a high cloud cover also was approaching, making light levels darker than they normally are by this hour. Many shorbirds were at the swamp when we
