Calidris bairdi
(10,13) Arroyo Chico, Estancia Medaland, 35 Km S. of Juanelo by road, Ptdo de Madariaga, Provincia de Bs. Aires, Argentina
5 September
(Cont'd)
There is an aggregative fascicella there with it. 1690 - no I must admit that it isn't territorial. behaviour, etc.
suggest both in terms of space-limitation or foraging and the topography of the behaviour (has seen
a helter-skelter-type supplant flight accompanied with cherr cell) but other behaviours aren't present and it
is not constant in supplanting. 1740 - slightly albinistic bairdi at curve; two several large white patches on
the wings.

0925 Several bairdi feeding in the water flew into the short-grass uplands and resumed feeding.
i.e. there appears to be interchange between the two groups of bairdi. 15 bairdi
feeding here on mound outside of Arroyo (see diagram in journal 5 Sept.)

0951: (See grid data book, journal, we sppacent). Baird's flew into feeding (clos 6 3 WR. at 0951 another
baird's flew in, chased as began to land, but the original one flew up, called, and the "intruder"
flown off. The first bird flew 15 m upstream but did not go with the "intruder". I put intruder in
quota (because I don't know if the chaser is territorial, or even if it actually chased the other bird off).

0825 (5,13) Small flock of mixed peeps, including the albinistic bairdi first seen 5 Sept. 6 bairdi
and 16 WR. downstream were smaller groups of n10 bairdi and 2 WR. 10 mow bairdi
slightly upstream between subunit 1 and # of the linear grid (n 2100 m of Arroyo). I found
several small groups of peeps. They were composed as follows:
