J.P. Myers 1971 Journal (1110) Estancia Medaland, 35 Km S. of Juancho by road, Pcto de Madariaga, Proia de Bs Aires Argentina 13 October (contd) the birds appeared to be coming into the coast area considerably later than 9 October, though not considerably so. Made for 9 October was the 1835-1845 period (incident vertical light ranges of 80-210 fc). Whether today modal movement occurred between 1845 and 1855 (IUC range of 10-50 fc). Thus, at least for these two samples, absolute value of light intensity do not appear to cause voicing flights earlier. If anything, they occurred somewhat later today total seen flying: Tryngite 559 Pluvialis 29. I suspect that the Pluvialis figure is so low because 1) we were near no extensive Pluvialis foraging areas (making early evening detection low) and 2) movements were occurring after light levels fell too low for us to make satisfactory sightings (see flocking accent). We remained in the vicinity until 2045, waiting for light levels to fall to a point where the night-light (strobe) would work — however, it began to rain steadily + we vacated. By dawn the next morning rain accumulated to 10mm. (1110) to (2215), Estancia Medaland, Pcto de Madariaga, Proia de Bs Aires, Argentina 14 October 1330 drove from Faranhouse Mount toward the 22nd Windmill with the intent of taking mininotopo data. It was a very warm afternoon, temperature reaching 24°. Modest NW wind, and a 5% cloud cover exaggerated by a heavy, threatening approaching haze. I encountered Pluvialis immediately upon leaving the mount, and began taking micro data immediately (see Pluvialis nightly record + spread). After getting 3 points from a series of Pluvialis groups between the mount & La Marga, I drove to the long stretch of Pectoral habitat near (2215). There was a good flock there (15 birds) and several Tringa flavipes 3 vagrants + 1 Tringa point. At 1745 I returned to the mount in order to pick up Lois so that we might night-light Tryngite. (1110) Estancia Medaland, Pcto de Madariaga, Proia de Bs Aires, Argentina At 1845 reached the (1110) region where we observed voosting Tryngite during 2 previous evenings. I quickly located several voosting flocks, and parked between them so as to facilitate finding them after dark. We waited in the car until 2045 when I could no longer detect any light difference between E-W horizon, and then began walking through the voosting area carrying a carbally hunting light, and hand net (0.5m diameter on 2m pole). Located 3 flocks, but netted only 2 birds, a Tryngite and a Pluvialis. (see flocking accent + band)
