J.P.Myers 197- Calidris fuscicollis (15,23), Estancia Medaland, 35 kms. of Tandil by road, Pto. de Madariaga, Provincia Bs. Aires, Argentina 27 November returning from (23,32) [Land airport, on the way up, too] we passed by the WR area described 13 November. today it is a bit drier and the mat of algae has broadened considerably. Birds here are territorial. They have been that way the last several times (which I passed. [as noted 14 November]) There is no central concentration of birds showing mixed behaviour territorial, pure + simple 23,32 Armyo Chico, Estancia Medaland, Pto. de Madariaga, Provincia de Buenos Aires, Argentina 29 November 08:30 we are at site where 27 November Rylg and a flock were scrabbling (see wr sp. accent) today the water is up, slightly (very slightly). We are at the site described for 27 Nov., and birds spread over 100 m S + 200 m Worth. All or almost all are territorial, exceeding 50, with territories of 5m + in length, some extending up to 20-40 m + both sides. However, I can't find Rylg A. Instead Ryly? to hue ~ 50 m S of Rylg's area. Ryly is territorial. It may have been there yesterday 27 November [note - it now reads Ryly as the orange has fallen off. I read its USP+WS # -042 - + was cut in of the reading]. Thus the territory size here is somewhat reduced when compared to that which we see in climatic conditions. (13,21) (sub 8-9) Armyo Chico, Estancia Medaland, Pto. de Madariaga, Provincia Bs. Aires Arg. 1020 - in contrast to all other areas of the armyo received this morning (from 23,32+ south 6 here), there is a flock foraging in an isolated drying stretch of the Armyo. Looks like another 'central area' type dispersal pattern. Plus (ca. birds are at least moderately 5-5, with surrounding birds being more so (10,13) Estancia Medaland, Pto. de Madariaga, Provincia Bs. Aires, Arg. 1120 - Rylg A to hue ! instead of at (15,23) - with a flock behaviour in mixed fashion ¿Que paaa ?
