Grid 9 (Farmhouse Puddle) Estancia Medland, 35 Km S of Juvanchoby road, Provincia de B.A., Argentina
17 December
(Cont'd)
No calibration wire left on the grid for the following count although they were in the [illegible]
(-1-0.5) area, being hassled by the lapwing pair. Small groups of shido continued to land
and fly away on the grid until the final count at 1930. Weather throughout
the afternoon was consistently cool (65-62°F), light rain during several of the counts, and
a moderate - strong NE wind.
18 December
Up at 0500 and on observation post over Grid 9 by 0530. First reading at 0600.
Weather as evening before, light rain, 62°F, mod-strong NE wind. Incident vertical light at
0530 = ~4 foot candles. Rain increased to heavy by 0645, at which point it became impossible
to use the spotting scope (rain on the lens) and I retired 2 samples, totals: [illegible] (sp; ave/cat,
(range) total): Pectoral, 3.5 (2-5)7; WR, 1.5 (0-3)3; Micropalama 2 (0-4)4; GYkep 0.5 (0-1)1;
S Lapwing 4 (4)8 - including 3 chicks/cat -; Speckled teal 3.5 (2-5)7; WFlbis 0.5 (0-1)1;
Anthus correndera 0.5 (0-1)1. I may have scared off a few lapwings upon arriving, as I believe myself
and had to climb into the blind upon arrival; however, the behaviour of other birds (five: 4 lapwings) on the grid
later during the morning suggested that the birds may have left for other reasons: It was not until the second
count (0630) that any of them stayed in our area for long. Most landing remained a few moments to minutes,
and then flew again. I do not believe it was a reaction to my presence, as there were no alarm notes, nor
alarm behaviour (bobbing) typical for birds that have detected me. One territorial pectoral in (3-4,-1)
Grid 3, 500m N of Farmhouse, Estancia Medland, 35 Km S of Juvanchoby road, Provincia de B.A., Argentina
After rain stopped (not as heavy as first appeared it would be) I had to drive out in the
blind to the Grid 3 area. First sample taken at 1300. Cloud cover still complete, with incident
vertical light ~500 FC. Temp = 68°F, wind moderate from 30°E of W. Birds received the car
and blind well as more flew, nor were we chased by foxes. totals (2 of 3a, 3 of 3b):
3a: Pectoral, 6 (5-7)12; WRump 0.5 (0-1)1; Micropalama 0.5 (0-1)1; GYkep 1.5 (15-16)31; GYkep 1.5 (0-3)3;
Goldenflower 0.5 (0-1)1; Shapwing 1 (0-2)2; Speckled tyrant 1 (0-2)2; Pseudoleide virecru 0.5 (0-1)1.
3b: Pectoral, 5.7 (2-9)17; GYkep, 2 (1-4)6; GYkep 0.3 (0-1)1; Cottamplorer 0.7 (0-1)2;
S Lapwing 0.3 (0-1)1; WFlbis 0.3 (0-1)4; Speckled tyrant 1.7 (1-3)5. [illegible] present thus
total despite the fact that I am not completely satisfied with the counts. Between samples, I followed.
