JPMyers 1973 Journal Arroyo Chico, from Farmhouse Road Bridge to Rte 11 Bridge, Estancia Mendoza, 35 Km S of Tumaco, Ruta de Buenos Aires, Argentina 24 November cont'd Thermals up to 10m. We followed the Arroyo ~4 miles to where it goes under or north Rte 12. During the entire trip, there was a strong wind out of the SE, the continuity of which increased during the afternoon, and also during one 20 minute squall at about 2:30. That was the only significant rainfall of the afternoon. However, most of the time 75% of the sky was covered by heavy cumulus. We followed the same route back (although cutting corners) arriving at the car by ~1900. The nature of the Arroyo does not change dramatically along the length that we covered (see yesterday's description). The surrounding fields are also fairly similar, most of them being short grass with thistle, or the woody plant described yesterday, or occasionally stands of short bunch grass. Buff breasted sandpipers, golden plovers, and southern lapwings could be found everywhere. White rumps, goldens, and Andean godwits were scattered along the length of the arroyo. One unidentified Charadrius plover in winter plumage; the bill was extremely short and I think it was probably scolopacidae. Species seen: neotropic cormorant, spotted nothura, Maguari stork, southern screamer, speckled teal, Milvago chimango, Southern lapwing, golden plover, semipalmated plover(?), WR sandpiper, buff-bellied pipit, H-godwit, brown headed gull, burrowing owl, blue and white swallow, wr swallows, [illegible], fork-tailed flycatcher, cornebundo pipit, Pseudoleistes virescens, Molothrus bonariensis, Sicalis sp., Bontrichia capucina. It was amplyed by the paucity of species. Farm house road, from Arroyo Chico Bridge to Farmhouse, and then W across country 2km Estancia Mendoza, 35 Km S of Tumaco by road, Ruta de Buenos Aires, Argentina After returning to the car (above) we drove E toward the Estancia farmhouse, turning left (N) just at the last fence before the compound. There is a dirt track that goes ~100 m, then W, then headed slightly S of W along the East side of the farmhouse marsh, following contours toward the first windmill and gate. Passing by here we continued on N till almost reaching the only tree in this direction (which is by a coral). We turned into the tall branches of scotse (?) and found a campsite. The wind kept up during the whole late afternoon, although noticeably decreasing in velocity. Cloud coverage dropped down under 50%. Of particular interest along this route was the series of ponds on Farmhouse Road just before reaching the farmhouse. There we found
