S.P. Myers 1974 Journal Linear grid: Arroyo Claro, Estancia Medallan, Peto & Nederiago, Pina de Bs. Aires, Argentoni 3 November We have been away from the estancia since 24 October, and approaching the riadumb it has not rained here since we left. It looks as much - the arroyo is a bare trickle in many places, although elsewhere it has even not shrunk horizontally. Dawn this morning at ~0545. I began reading the linear grid at 0629 - a slight NE wind was up, temp = 17°C, clouds 90% and an ave of ~2000 ft. grid totals: Calidris fuscicollis 31 (!), Calidris baicalensis 3, Calidris melanotos 1, Arenaria interpres 1 Tringa linosa harrimaniae 1, Tringa flavipes 2, Vanellus chilensis 1, Pluvialis dominica 6, Rhodostethia falklandicus 2, Ch. collaris 1, Himantopus 4, 8, Anas georgica 5, Anas flavirostris 2. The remarkable feature of today's grid reading was the large number of sandpipers and the species diversity. In addition to the number of fuscicollis present, the sample was remarkable for the number of territorial fuscicollis (which I saw while doing it). By the time that I had finished the sample the wind had shifted to out of the W and grown in strength to moderate. Running down totals: Calidris fuscicollis 31, 39 (110); C. baicalensis 5, 13 (18); C. melanotos 1, 2 (3); Thiacopelma 1, 2 (3) Tringa 1, 1 (2); Tringa linosa harrimaniae 1, 6 (2); Tringa flavipes 1, 4 (5); Vanellus chilensis 0, 1 (1); Pluvialis dominica 2, 2 (9); Charadrius falklandicus 1, 2 (3); Charadrius collaris 10 (6); Himantopus 3, 5 (8); Steganopus tricolor 2, 1 (3) Anas georgica 16, 0 (16); Anas flavirostris 8, 0 (8); Larus maculipennis 0, 3 (3). 5 old banded Cark one from this year (see roughing chart). During the count I found territorial WKA on 10+ 10, 10-9, 9, 8, 4-3, 3 and 3-2 (see running down data sheet). — general note. In the afternoon (~1530) a violent windstorm developed, quickly cooling down the excessive temperatures, and delivering early afternoon (30°C+). It developed into a lengthy thunderstorm. At some time during late afternoon winds reached sufficient velocity to tear the blind off of the tower placed in the 1/8 region. Oh well. When we found it the next afternoon it was hecho oil pedegos total. Every knot in the frame had found a way to break. I only hope that it fell on top of a cow. The storm produced a miniscule quantity of rain. 4 November The storm continues, still without rain but sufficient wind to fill any sail. We arrived at subunit 7 of the linear grid at 0834 and began sampling. Cloud cover was low and heavy, there were a slight drizzle and strong S wind.
