JPMyers 1974 Journal Mouth of Canal 7 into Laguna Mar Chiquita, 21 km N of Mar Chiquita, Pteide Bs Aires, Arg 24 August (con't) Larus dominicanus Agelaius thilius Circus buffoni Pseudoleistes virescens Cinclodes fuscus Zonotrichia Gallus Plurocyptes Eubernagra Athene sp. Estancia Meduland, 35 km S. of Juanjacho by road, Pteide Madariaga, Provincia de Bs Aires, Argentina 25 August (morning - see camp list p19) 1530 drove w/east NE from the Farmhouse camp out past the first two windmills (see map journal Aug 23). Weather 13°C, N wind (flight) and total overcast. Vegetation out in this direction from camp trampled and only beginning to show green. Solanum not yet growing. Beginning just approximately 1500m SW of the second windmill, however, and ranging beyond the point where we were stopped by impassable conditions, is water!! Beautiful pectoral and Gallinago habitat - a filled drainage area varying between 100% surface water, an intermediate stale with grass emerging out of the water and occasional clumps of dirt, and grassy green areas out of the water but obviously saturated. Snipe were common, with second displaying (see ap. accent) and others moving in groups of 2-4. Transtillarostis were in the water, and a flock of pectorals came by near the end (see ap. accent). I suspect that this area is so wet because it is a shallow but extensive hollow with a large draining area. Unusual bird for Mtdeland: Xolmis dominica. 26 August BOW Dawn cloudy, 9°C at 630. Left camp at 0730 and followed route taken 8-23, as far as the Rte 11 Bridge (see 8-23 map). Then crossed Arroyo Chico, went through gates E,F,G, and H, and returned to camp via farmhouse road. Drizzled several times for a short period. Moderate N wind developed through the morning. 100% clouds throughout, sometimes quite low. As I returned along farmhouse road, it was obvious that the ploining of Towerllanos had started. Anyway. Thinocorus almost gone. Zonotrichia still heavy in upland. Oreopholus very common, 300-400 easily. Somegolubus ~15 Baird's upland, a few along the Arroyo, >10 CW in Arroyo. Ch. fallaxlantius and Acanthiornis in both habitats, but in neither abundant. See app. accounts.
