JPMyers 1974 Calidris fuscicollis 09 Tower Llanos, Estancia Medeland, 35 km S. of Tucumano by road, Dtpto de Mendoza, Provincia de Bs.Aires, Argentina top of the corn pile and working around it. 23 January control 27 January See Journal - banded one WR after catching it on Grid 10 11 February found banded WR (R Yellow L Green - [illegible] banded 1 January Grid 9) in Arroyo Chico at N end of Tower Llanos. The bird has a territory on the section of the linear grid which extends through the fence. Bird is defending 20 m on both sides of Arroyo. See journal WR 12 February Attended surveyed the linear grid for WR between 1700 and 1738 - found 64 foraging birds in 3 km, then a flood of 59 birds just at the end of the grid; these latter birds were mostly resting + preening up off the water in the mud (attacking in depressions caused by cow tracks). 3 banded birds - R Yellow L Green (1 January Grid 9; seen yesterday) - territorial in same spot; R Red L Red (27 January Grid 10) - in linear grid subunit #2; R Yellow L [illegible] (1 January Grid 9) - linear grid subunit #3. 13 February Netting + banding WR at the swamp at the E end of the Tower Llanos. I estimate there to be over 200 cormorants, but that in a very rough estimate as I've seen the whole flock (or what is probably the whole flock) flying once only twice, the WR are not approachable. (Solar Sunset). Instead of coalescing completely into one area, they are spread spottily in small groups over a 200 m stretch of swamp. At this time there is much movement, with small groups wandering along the channels of the swamp, low through the openings (between tufts). Small groups continue to come in from away from the swamp - must that I have seen flying from the W. 2115 - went to unfurl nets after 2100 sunset; 2 WR already in nets. 2300 - total of 7 WR banded, one salvaged from net (082) 14 February 1830 above length of Arroyo Chico farm fence at S end of Tower Llanos to Fence at N end of linear gird - a winding distance of ~4 km. We counted WR en route: between the first fence + the end S end of the linear grid (~1 km) - 37 WR now banded. Along the linear grid (3 km) - 24 WR, one banded. [R Yellow L Green - this bird is still territorial in the same location, on both sides of the Arroyo on both sides. This is the 3rd time in 4 days he has been there (every time we've looked he has been for +1 days).] Birds were spottier today than 12 February + their movements - a result of the sparrows - probably caused a slightly higher count. We found no large roosting group as 12 Feb, but there were indications that such a group was forming as we left. 15 February counted WR along the Arroyo between the fence at the S end of Tower Llanos
