J.P. Myers 1974 Journal 10 January (Cont'd) Rte. 1. Pond at Farmhouse Rd., Estancia Medelar, Ptdo de Madariaga, Pcia de Bs Aires, Argentina (species account). Collected one timbrid (Federal #065) and one timbrid whistling (066) at 1645 then drove back along farmhouse road Grid 4 (Tower Llanos), Estancia Medelar, Ptdo de Madariaga, Pcia de Bs Aires, Argentina On the way back from Rte. 1 pond we checked out the path to Grid 4 in order to see if it was accessible. Many golden plopped in the 'Jawbone' field, but only a few buffle. Immediately pushing through the gate at the end of the corn field, and entering into the Llanos, started to see more buffle. However, the numbers were not very impressive (>100). The Llanos, for the first time since our arrival, show no sign of growth above the 1-2" level (in the non-thrift contaminated area). But it is ragged + sparse, and apparently just overlapping seed heads of old Juncus, perhaps a few more. The ditch proved to be comparable for the carriwader still flowing swiftly despite no substantial rains for several days, and excellent singing condition (abundant wind, sun + warm). Indeed the lower areas of the Llanos still have a film of standing water. We pitched a campsite at the edge of the ditch on a direct line between the gate and the tower, and will return this evening so that tomorrow morning will be in good position for netting. Tower Llanos Grid 1, Estancia Medelar, Ptdo de Madariaga, Pcia de Bs Aires, Argentina Passed through Grid 1 and Grid 9 acres via Farmhouse Road in car at 1830. No Shorebirds on Grid 1, and now apparent on Grid 9. Whump Yellow Right is again in the middle between (Grid 1) and the Farmhouse Road gate before reaching the farmhouse. Grid 4 (Tower Llanos), Estancia Medelar, Ptdo de Madariaga, Pcia de Bs Aires, Argentina (temporarily) Returned to campsite shortly after sunset. We are right beside a small pond (70' x 20') that earlier in the past been dry. One timbrid we on it, and possibly others, also possibly burrowing) on a larger (4 x 20) pond about 50m up the dale. 11 January Up at 0215 to chase cows from around the tent. Moon just passed full, and at 0215 quite high. Temp lower than in other recent evenings (7°C at dawn). Wind did to a very slight breeze. At 3h 3m we marked down to finally get the cow away, forgot. Up at 0530 to place nets. Walked from camp to tower, and found considerable trouble with the nets because of the loose substrate - I put the first net on Grid 7 on the Llanos
