JPMyers 1974 Journal Estancia Medeland, 35 Km S. of Trenque by road, Pto de Madariaga, Pcia de Buenos Aires, Argentina. 20 March (contd) Charadrius falklandicus 2,11(13); Hudsonian Godwit 0,14(14); Greater Yellowlegs 0,1(1); Neotropic Cormorant 0,1(1); Southern Lapwing 0,1(1); Speckled teal 2,0(2); Brown-hooded gull 0,1(1); Correndera pipit 2,0(6). After completing the sample we scoured down the grid, searching for banded birds. Total: White-rump 13,29(37); Charadrius falklandicus 15,29(44) Greater Yellowlegs 0,3(3); Southern Lapwing 0,3(3); Neotropic Cormorant 1,7(8); Speckled teal 0,13(13); Southern Screamer 2,1(3); Brown hooded gull 0,1(1) 2,4(6); (cassitta 1,0(1)); Correndera Pipit 0,3(5). We found 6 banded WR, 3 banded falklandicus. The first Total (i.e. WR) is appalling, so is the total # of WR seen - 37, the lowest yet. At the same time, it is very interesting, because all but 2 of the WR found are known, familiar, and those two are too flocking birds which occur only irregularly. They, the main flock(s) in which such regulars as Ryllys cavori, are elsewhere. What remains to be seen. Tower Llanos, Estancia Medeland, Pto de Madariaga, Pcia de Bs Aires, Argentina. 1215 - Stock of 20 bufflits in llanos by S fence. Also found a few Thincorvis, but I did not search extensively for them. Estancia Medeland, Pto de Madariaga, Pcia de Bs Aires, Argentina I am writing this with a more general locality heading because the expedition involved several areas on the Estancia. At 01430 I set out from the farmhouse, slapping Srvit 1 km W along Farmhouse Rd in order to investigate the swamp which runs from due North. 15 March I found a banded WR there. Today there were none, only a solitary Lesser Yellowlegs. Water had receded at least 5', reducing the remaining surface water to less than 10's 40'. Borderd by a wide strip of caked mud. Sign of WR foraging eg footprints, was not overly abundant. From land continued out to Tower Llanos via the fallow cornfield, cir which, for the first time there I found Thincorvis, a flock of ~15. From here I continued to Tower Llanos Swamp only to be dismayed by the paucity of shorebirds - there were 14 Cadwitz, but less than 17 White-rumps total (no bands). Greater Yellowlegs and Lesser Yegs were also also reduced (~15 each). A few Nyctivaghus speared in unison from one area near the S end of the open water. The main body of water is now all accessible to foraging birds.
