Calidris fuscicollis Arroyo Chico, Estancia Medeland, 35 Km S of Juncal by road, Ptd de Madariaga, Pcia & Bs As, Arg. point where one van at the other, pushing the other out (literally) 25 April (cont'd) due Mekland Tajamar, 1.5 Km W of Farmhouse, on Estancia La Atlantida, Ptd de Madariaga, Pcia de Bs As, Argentina 1130-1200 see map in journal. 150+ WR foraging in the Tajamar, which contains a surprisingly amount of water in comparison with the Arroyo. A considerable % of WR are territorial; I would estimate 50% plus perhaps 80-90% along the narrow mud border, and a smaller % (for maybe the same) where habitat appropriate for WR's opens up into a broader area, + where there were more WR. While walking around the Tajamar I kept the population in a constant view; the presence of ten individuals was very apparent. One band heard Ro Lago. No other bands, despite a diligent search. 26 April Arroyo Chico, Estancia Medeland, Ptd de Madariaga, Pcia de Bs As, Argentina Ryloo with Ro Lory and 20 other WR between subunits 9 and 3 at 0930. Ryloo was in a flock on subunit 6, along with Rplr and RyLpy, RoLrr. There are other bands (wide present - one Chf. [Rylo]) and one Zorilpyx (Ro) which had likely been territorial on 7 or between 8+7; they later became now day, suggesting that the flock moved downstream. Flechero Bay, 1 Km S of Punta Canos by beach, Golfo San Jose, Peninsula Valdes, Chubut, Argentina 6 May 20 or so WR foraging on the broad sand-mud flat with a few sanderling and many Charadrius falklandicus. Very little sign of any body molt. Skittish. 27 May 1 WR at the 3s near low tide line this morning, foraging near a few falcklandicus
