Aires, Argentina 31 May 1615 drove from Farmhouse to Tower Llanos to N. end of Linear grid. Moderate NE wind, 98% clouds, temp ≤ 15°c. According to the Estancia residents, it has rained only twice since we departed from here in early May; once soon after we left, and then again only a few days ago. Weather rain were very substantial, as they said, but the land is obviously wetter now than it was when we left: standing water by the road, thick mud in some place, + the Arroyo is flowing. It's narrowest point in Potreros 19 chico and 20 is now by linear grid subunit 4, which it is 1/3 across. My route this afternoon entailed driving along Farmhouse Rd to the turnoff to Tower Llanos, S of the entrance gate, then N into Tower Llanos, over the ditch around the main thistle patch, past the Tower and grids 4 and 7. Then after leaving the Llanos I entered the Arroyo Chico at subunit 4, and followed it N to the end of Potrero 19 chico (i.e. the Nord of the linear grid). Here I turned around (~15:30-17:30-sunset) and followed the Arroyo back to the End of Tower Llanos (Potrero 20), and returned to the farmhouse, spp observed; (sp., total #, #in Tower Llanos, # in Arroyo) Magnani stork 4,0,2 Tringa [illegible] melandruca - 3,0,3 Thelitis caudatus 4,0,0 Gallinago 6,6,0 S. screamer 4,2,2 Cynus melanocoryphus 2,0,0 Anas flavirostris 4,0,4 Anas georgicus 2,0,2 Polyborus plancus 2,0,0 Milvago chimango 5,4,0 Vanellus chilensis 34,7,12 Charadrius falklandicus 64,0,64 Zonibyx modestus 141,32,9 Oreopholus [illegible] 91,79,3 Thincorus ruficollis 175,175,0 Larus dominicanus 1,1,0 Zenaida auriculata 25,0,0 Columba picaguro 5,0,0 Colaptes campestroides 3,0,0 Fornaris rufus 2,0,0 Reoistha cucularia 3,3,0 Cinclodes fuscus 20,5,15 Teguara [illegible] 11,3,8) Anthus concolor 3,3,0
