JP Myers 1973 Journal Farmhouse Eucalyptus Grove, Estancia Medeland, 35 km S of Juancho, Pcia de B.A., Argentina species within the woods live as soon as identify some of the tyrants. During this today's rain several deep puddles have appeared within the grove, suggesting that there may be a significant change in the shrewbird habitat as the process may be in progress. Farmhouse pond (Grid 1), Estancia Medeland, Pcia de B.A., Argentina 5 December 0700 walked down the campsite in the Grove out to Grid 1 during a break in the rain. During the night it continued to rain, accumulating 10 mm. Grid 1 has been completely covered with water, the pond now refilled to the edges of its mud banks. Previously, yesterday at dawn it was broken into 3 distinct puddles separated by stretches of dry or almost dry mud. This morning it is a continuous pond; all of the muddy areas where Pectorals and we were foraging previously have been covered. Along the road in this stretch between the farmhouse and the first gate, the many puddles that had dried or were almost drying have filled to the point of overflowing. Stretches of grass are an inch deep in water. And thus morning the rain is continuing, although intermittently. Huici tells me that last year of 23, 24 and 25 December there was a similar storm that dumped considerable amounts of rain. There are shrewbirds foraging in the newly inundated grass areas—Nothing on the grid, but along the edges is a flock of WR, a) about 30 m to the W in a small puddle (grass lined) is a group Pectoral, a wr and a Veg. In another more extensive but newly formed puddle is a flock of WR, Ibis, Agelaius, Xiphias. 500 m W of Farmhouse, Estancia Medeland, Pcia de B.A., Argentina 1500 we walked W from the farmhouse toward the windmill. Drizzling, the precipitation driven hard by a strong SE wind which continues unabated. From Farmhouse road all the way to the windmill is now an almost continuous puddle, 700 m wide in some places, and reaching 0.3 m in depth. Flora are WR, Veg (mostly lesser), Pectorals, Stilt Sandpipers, Terns, WFBird along the length, distributed unevenly. A few spots, one in particular at the W end of the biggest pond in the series (on the downwind side) was notable for the number of WR
