SPM Myers 1999 Journal 48 15 March (cont'd) Belo Arroyo Chico, Estancia Medland, 55 km S. of Juancho by road, Ptdo de Madariaga, Pcia de Buenos Aires, Argentina After having read the map, I must qualify it now - it seems only in a ranking system. But it does have local merit. So, I walked along the Arroyo from the Send of Paterno 19 to the Rt 22 Bridge, a distance (on way) of no more than 5 km. Beside the streambed already noted, found a small flock of thincocorus in the brigh on the raised bank of the Arroyo. Other than Shovelers, the dominant birds were ducks: 100+ YB Speckled teal, at least 50 YB Pintail, some Area versicolor, and some Shoveler. But on the Arroyo were rhea, southern screamer, burrowing owls, cinereous + long-winged hammers, Rufous-backed negrito, Correndera pipit, Cliff + WR swallow. Of course Willet and Palyburs. 1 km E of Farmhouse by road, Estancia Medland, Ptdo de Madariaga, Pcia de Buenos Aires, Argentina Stopped by on route to camp when I spotted a flock of WR foraging by the road in a swamp just to the W. of the road. 20 WR, including RyLg. 9 Hudsonian godwit, 5 Lesser Yllega. This bird brings today's total of banded WR to 17!! Arroyo Chico, Estancia Medland, Ptdo de Madariaga, Pcia de Buenos Aires, Argentina 17 March Temp: 8° at 0800. (Began reading linear grid 0847. Wind had already risen from S (slight), the clouds = 0. Wiktrumps down today, but not reflected entirely by totals: White rump 7,29(36); Charadrius falklandicus 6,12(18); Hudsonian godwit 2,5(7); Greater Yellowlegs 3,0(2); Black necked Stilt 1,4(5); Southern Lapwing 0,5(5); Speckled teal 2,14(16); Shoveler 0,4(9); Brown-headed gull 0,3(3); Correndera pipit 1,0(1). Although the on-the-grid total is high, it is deceivingly to having picked up RyLr's flock on subunit 4, adding 18 birds to the 18 seen elsewhere. 'Running dawn' totals do not reflect the WR situation: (White-rump 28,49(7) between Charadrius falklandicus 23,27(50); Hudsonian godwit 6,1(7); Greater Yellowlegs, 2,0(2); Black necked Stilt 13(4); Southern Lapwing 0,2(2); Metropica crassirostris 0,10(0); Speckled teal 1,24(25); Shoveler 0,4(4); Cocoi heron 0,1(1); White-faced ibis 0,1(1); Southern screamer 0,2(2); Brown-headed gull 7,6(13); Rufous- backed Negrito 1,5(4); Correndera pipit 1,2(3). Only 7 banded WR found this morning. At least one territorial bird was gone (RyLop). As in the past 2 days, all Arroyo birds were spooky - taking off at the call of a trio. Was my collecting in the linear grid unwise? Or are the WR's getting away. Patagonia
